Chapter One – What is a Warehouse Racking System?

Warehouse racking systems, often referred to as storage or pallet racking, are essential material handling solutions developed to facilitate the large-scale storage of goods placed on skids or pallets. These systems enhance space efficiency and provide easy access to stored materials, leading to better inventory management. Such systems are especially advantageous for manufacturers that need to store large volumes of non-perishable products due to limited storage availability. While conventionally, palletized goods are safely stacked up to three tiers, a racking system enables stacking these palletized goods five to seven tiers high, contingent on the facility's ceiling height, thereby significantly boosting storage capacity.

Very Narrow Aisle (VNA) Racking

Besides managing finished goods, racking systems are also employed for storing raw materials and components. Selective racking systems are devised to optimize item accessibility, supporting a diverse array of products. Some distribution networks implement the FIFO (First-In, First-Out) inventory management strategy, ensuring the earliest-stocked items are the first to be accessed and shipped. This method aids in efficient inventory control and diminishes the risk of product obsolescence.

Chapter Two – What are the benefits of a racking system?

Aside from optimizing storage space, implementing advanced warehouse racking systems brings a wide array of advantages for inventory management and supply chain efficiency. The benefits of warehouse racking can be measured not only in terms of maximizing cubic storage, but also by reducing operational costs, improving warehouse layout, minimizing downtime, and supporting higher throughput. Companies installing modern industrial shelving, pallet racking, and storage rack systems often experience significant savings on leasing additional warehouse space, reduced workforce effort through improved accessibility, and a measurable increase in order processing speed. Additionally, ensuring compliance with OSHA safety standards and robust warehouse management protocols—while not always yielding immediate ROI—adds long-term reliability and value by reducing workplace accidents and product loss. Below are some of the key benefits of implementing a warehouse racking system:

Very Narrow Aisle (VNA) Racking

  • Efficient storage space utilization: As mentioned earlier, racking takes advantage of the available vertical space that is otherwise unused. Warehouses that are designed to accommodate racks are constructed with high ceilings to allow racks with higher bays, such as drive-in racking and very narrow aisle (VNA) pallet racking systems. This maximizes floor space and increases density, which is especially valuable for industries managing seasonal or high-turnover stock.
  • Easy inventory organization: Racks can be addressed easily in comparison to stockpiling. Storing goods with many distinct varieties is virtually impossible with stockpiling without consuming large floor spaces. A type of racking system known as selective racking allows storing different types of goods while keeping the consumed space to a minimum. Inventory tracking via a Warehouse Management System (WMS) is also more accurate when items are systematically organized on shelves and racks, supporting better SKU control, batch management, and FIFO/LIFO picking strategies.

    Separate Palletized Loads

Fewer Damaged Goods

The evolution of racking systems was driven by the need to prevent damage to goods and products during storage and handling. Originally constructed from wood, today’s advanced metal warehouse racking—such as steel pallet racking and cantilever racks—are engineered for high stability and durability, enabling businesses to safely stack goods several feet high, limited only by building structure and local regulations.

Palletizing materials not only simplifies shipment organization and supply receipt, but when paired with a professionally engineered racking system, ensures each load is securely stored to prevent mishandling, accidental contact, or dropping. Strong metal frames stabilize pallets, minimizing risk of tipping or collapse, and many systems include load beams and decking for additional support. With options ranging from push-back racking and double-deep racking to highly automated AS/RS (Automated Storage and Retrieval Systems), businesses gain both damage protection and operational flexibility. Racking systems also allow for easy access to each SKU, reducing the risk of disrupting surrounding inventory during retrieval.

Increased Employee Productivity

In a racking system, the location of empty or occupied pallets can be quickly identified and accessed thanks to improved labeling, barcoding, and digital inventory tracking systems. This streamlined process reduces unnecessary movements, such as excessive walking or searching, and promotes faster order picking and restocking. Over time, these incremental efficiency gains prevent minor inefficiencies from accumulating into substantial productivity losses, supporting higher workforce output and smoother warehouse operations. Additionally, clear aisle layouts and well-planned picking paths decrease congestion and enhance overall workflow, further optimizing labor costs.

Storage Automation

Adapting a racking system is the first step to warehouse automation and scalable storage solutions. By integrating smart conveyor systems, automated guided vehicles (AGVs), and automated forklifts and cranes, companies can automate pallet handling, replenishment, and retrieval processes. These high-tech integrations can lead to significant savings in manpower costs, reduce manual errors, and streamline the business process, especially for large distribution centers and e-commerce fulfillment operations. With the adoption of technologies like RFID tracking and AI-driven inventory control, racking systems become the backbone of a smart warehouse infrastructure.

Guard Rails

Increased Safety

Warehouse racking systems are intentionally designed to maximize storage capacity while upholding strict safety standards. Properly engineered racking facilitates organized storage, efficient space allocation, and quick retrieval of items through effective product cataloging and order picking strategies. Warehouse safety measures are critical to maintaining operational efficiency and are embedded in quality racking system design. Essential safety features—including sensors and alarms, guard rails, rack end protectors, rack guards, and column guards—protect employees, products, and physical infrastructure from common hazards.

  • Guard Rail Systems: Guard rail systems made of heavy-duty steel are installed in high-risk areas to provide physical barriers and shield valuable equipment and personnel. Their robust construction helps prevent accidents and reduce the risk of costly material damage from forklift collisions.
  • Sensors: Advanced sensors with visual and audio alerts improve awareness in busy warehouse aisles and intersections. These systems help prevent collisions by indicating the location of shelving, detecting approaching forklifts, and signaling the presence of automated equipment or staff.
  • Warehouse Software: Modern warehouse management software not only enhances inventory accuracy but also calculates optimal storage patterns, evaluates safety risks, and suggests the safest, fastest routes for moving goods. By tracking picking frequency and item popularity, these solutions automate product placement decisions and help reduce manual handling—minimizing workplace injuries.
  • Rack End Guards: Installed at the end of aisles, rack end guards absorb impacts from vehicles and equipment, protecting the base of racks. They are often brightly colored (e.g., safety yellow) for high visibility and designed with low profiles to accommodate safe traffic flow, clearly differentiating them from column guards.
  • Column Guards: Warehouse column guards come in various shapes and sizes to fit different racking systems. These floor-mounted guards wrap around the lower portions of upright columns to shield them from damage by pallets, forklifts, or pallet jacks. Their installation prolongs rack lifespan and prevents structural failures.
Integrated Fire Sprinkler

Clean and Contaminant-Free Handling

Racking systems improve access to all stored goods and create organized aisles for easier cleaning, dusting, and maintenance. This not only facilitates routine facility cleaning but also enhances product hygiene, which is crucial for food and pharmaceutical storage applications. Effective segregation of products allows for the separation of goods with different storage requirements, helping to prevent cross-contamination, spoilage, or damage to sensitive inventory. Moreover, elevated racks can aid in pest control by minimizing floor contact and exposure. Businesses seeking compliance with FDA or GMP warehouse standards can leverage advanced racking solutions to achieve sterility, traceability, and secure storage for regulated inventories.

    Chapter Three – What factors should be considered when designing a racking system?

    Before investing in a warehouse racking system, it’s crucial to evaluate a comprehensive range of factors to ensure the solution meets your operational needs and aligns with best practices in warehouse management. Although storage racks are engineered to maximize available space and improve inventory control, they do inherently occupy some square footage with their steel frames and necessary accessories. One significant limitation to consider is the potential difficulty and cost involved in modifying or reconfiguring commercial racking systems once installed. To maximize your return on investment (ROI) and create a scalable, efficient storage solution, keep the following key considerations in mind:

    Racking System

    • Available Storage Space: Assess the total floor plan available for constructing storage racks and verify whether the warehouse layout accommodates these structures while still allowing efficient traffic flow for forklifts and other material handling equipment. For existing warehouses, consider that the full floor area is rarely entirely usable due to fixtures or building constraints. Be aware that industrial pallet rack systems are typically manufactured in standard sizes, and their footprint affects net storage capacity. Additionally, evaluate if warehouse features—such as columns, partitions, or fire exits—may require modifications to fit rack systems securely and safely.
    • Vertical Clearance: Optimize not only horizontal floor space but also the available vertical clearance to improve storage density and cubic utilization. Rack-supported mezzanines can make use of vertical space, but must be planned with awareness of fire suppression system clearances, adequate lighting, and HVAC system airflow. High-density racking, such as drive-in racking or gravity flow rack systems, can exploit vertical room, but may require sacrificing a layer for necessary slopes or operational clearances. Overextending stack heights could impact critical warehouse infrastructure and may incur additional costs for compliance modifications.

      Fully Utilized Vertical Clearance Using Racking System

    • Unitized Load Dimensions: Evaluate the shapes and sizes of palletized loads to ensure the racking design aligns with your primary storage needs. Customizing racking beams or wire decking to accommodate standard pallet sizes, such as GMA pallets, euro pallets, or bulk containers, can increase storage efficiency and ensure both safety and ergonomics. If dealing with various SKU sizes, consider designing the system around the largest dimensions for flexibility, or use adjustable racking systems to maximize adaptability.
    • Load: Select racking materials and construction methods that match your operational requirements. Most industrial shelving is engineered from robust steel—cold-rolled for lighter loads, and hot-rolled or structural steel for heavy-duty warehouse pallet racks. Always verify the maximum load capacity per bay and per shelf to prevent overloading and to comply with OSHA and local building code regulations. For specialized inventory such as cantilever racks for long materials, or push-back racks for deep lane storage, choose structural components scaled to expected weights.

      Heavy Duty Racking System

    • Target Capacity: Determine your target warehouse capacity utilization by analyzing both current and future storage requirements. This includes understanding key performance indicators (KPIs) such as inventory turnover ratio, average days on hand, and stockroom flexibility for handling both steady-state and seasonal inventory fluctuations. Overestimating storage needs can lead to excessive investments and increased ongoing costs, while underestimating can create supply chain bottlenecks and loss of revenue opportunity. Ensure compliance with fire code capacity standards as well.
    • Volume of Incoming and Outgoing Goods: Calculate your warehouse throughput, including average and peak volumes for inbound shipments, outbound distribution, and reverse logistics. This throughput analysis will help you select between selective racking (for high pick frequency SKUs) and high-density systems like double-deep racking or pallet flow racks (for larger quantities of homogeneous products). Plan to accommodate changes in production schedules, e-commerce fulfillment demands, and any anticipated surges during promotions or holidays.
    • Number of SKUs: Identify the total number of stock keeping units (SKUs) your warehouse must accommodate. Higher SKU counts call for greater selectivity—such as selective pallet racks or carton flow racks—to ensure fast access, accurate inventory tracking, and efficient order picking. If the facility manages lower SKU diversity with larger volumes per SKU, systems like push-back or drive-in racks may deliver higher storage efficiency. Evaluate your WMS (warehouse management system) integration needs for real-time tracking and optimization of inventory locations.

      Rack Storage Systems

    • Type of Inventory Accounting Method: Clarify whether your inventory management is based on FIFO (first-in, first-out), LIFO (last-in, first-out), or FEFO (first expired, first out) principles. This impacts the optimal racking configuration. FIFO-assist systems such as pallet flow racks prevent products from aging, which is especially vital in food, beverage, or pharmaceutical storage. In contrast, LIFO systems, like drive-in racks, prioritize efficiency for non-perishable goods where inventory rotation is less critical. Select racking systems in alignment with your supply chain and inventory rotation strategy.
    • Investment and Operating Costs: Carefully forecast the total cost of ownership for the racking system, considering not just upfront capital expenditure on racking components, but ongoing maintenance, safety inspections, and potential disruptions during installation. Compare cost-per-pallet-position across system types; selective racking may range from $50 to $100 per position, while high-density systems can exceed $250, especially when factoring in automation or specialized storage needs. Factor in long-term value such as improved warehouse safety, enhanced productivity, compliance with OSHA standards and local codes, and the potential to reduce labor and space leasing costs. Explore all ROI opportunities, including energy savings, reduced damage or losses, and insurance premium reductions through improved risk management.

    When planning your warehouse racking system, also weigh secondary considerations, such as seismic zone requirements, forklift aisle widths for optimized material handling, future scalability of storage solutions, and environmental factors like temperature or humidity needed for climate-controlled storage. Choosing the right type of racks—such as selective racking, carton flow racks, cantilever racks, or automated storage and retrieval systems (AS/RS)—with a reputable racking supplier is vital for long-term operational efficiency.

    Ultimately, investing in the correct warehouse racking system helps increase inventory turnover, enhance workplace safety, and optimize material handling processes—all cornerstones of modern supply chain management. Careful planning and strategic selection deliver tangible cost savings and keep your warehouse operations competitive within the logistics industry.

    Chapter Four – What are the different types of warehouse racking systems?

    Racking systems come in various designs and configurations tailored to specific applications. Generally, storage racks are categorized into high-selectivity, low-density or low-selectivity, high-density applications. High-selectivity, low-density racks include selective, double-deep, and very-narrow-aisle systems. Conversely, high-density applications encompass push-back, drive-in, and pallet flow systems. Additionally, there are specialized systems, which are essentially adaptations or modifications of these standard configurations.

    Selective Racking System

    Selective Racking

    Selective pallet racking is designed for high SKU counts but offers lower storage density. It is often visualized as large shelves with space for a single row of items. Although racks can be arranged back-to-back to enhance storage density, the overall density remains low due to the space occupied by aisles. This type of racking is commonly used in warehouses for raw materials, parts storage, and distribution centers where there is a wide variety of products in low volumes. Selective pallet racking can be combined with other racking types to handle SKUs with higher volumes. Key benefits include flexibility for FIFO and LIFO inventory management, compatibility with standard forklifts, ease of cleaning and inventory management, and straightforward construction that allows for easy reconfiguration. Selective racking also features various frame and beam connection designs, including teardrop and slotted racks.

    • Teardrop Racks: Teardrop racking is a type of selective racking with modified frame and beam attachments that can be reconfigured and expanded easily without the use of machine tools. Upside down teardrop-shaped holes are punched along the upright frames, where pins attached to the beams are inserted. As the pin falls into the tapered opening, friction secures it in place without requiring additional fasteners. This connection has enough strength to be comparable with permanent joints. Adding heavier loads causes more friction to fix the beam in place. Wire decks are placed above the beams that become shelves for the pallets. Appurtenances such as pallet supports, crossbars, ties, and anchors are added to further strengthen the structure. Teardrop pallet racks are usually produced by roll forming in which metal sheets are cold-rolled into rectangular frames and beams.

      Teardrop Racking Components

    • Slotted Racks: These are sometimes referred to as structural racks. Instead of using upside-down teardrop-shaped holes, slotted racks have a pair of rectangular openings milled along with the upright frame. The frame and beam can be attached by hooks protruding from the beam or by bolts. The main advantage of using slotted racks over teardrop racks are their higher durability and strength. Slotted racks are produced from hot-rolled structural steel, making them more robust than teardrop racks. Higher gauges of sheet metal are used to allow a higher load-bearing capacity. The downside of using slotted racks is their higher cost and weight.

      Slotted Racking Components

    Double Deep Pallet Racking

    Double-deep pallet racking is an enhancement of standard selective racking, where each pallet shelf holds two rows of pallets instead of one. This modification increases storage capacity by 40-60% while retaining many of the benefits of traditional selective racking. For FIFO inventory management, adjacent rows must contain the same SKU, which improves storage density but reduces selectivity. A notable disadvantage is the requirement for specialized forklifts or standard forklifts equipped with double-deep handling attachments, leading to higher operating costs and the need for well-trained operators.

    Double Deep Racking System

    Very Narrow Aisle (VNA) Racking

    The concept of very narrow aisle (VNA) racking is to enhance space utilization while maintaining 100% selectivity, building upon the standard selective racking system. This is achieved by using a side-loading forklift, which allows pallets to be loaded and unloaded without the need for wide aisles. By minimizing aisle space, VNA racking can reduce the aisle width by up to 40%. However, a drawback of this system is the requirement for two types of equipment: a side-loading forklift for accessing the racks and a standard forklift for transporting pallets between the palletizing station and staging area.

    Side Loading Fork Truck (VNA Forklift)

    Push-back Racking

    Push-back racking involves loading pallets onto carts that rest on rails within each lane of the racking system. These carts are positioned at the front of the aisle and are designed to nest together. To load a pallet, a forklift pushes the pallet into the lane, causing the existing pallets to move further back. This dynamic system enables higher storage density compared to single or double deep racking. Each lane typically holds one SKU and can be configured to accommodate three to six pallets deep. Because the pallet being accessed is always at the front of the lane, specialized deep-handling forklifts are not necessary. The lanes are inclined to facilitate the rolling of carts towards the aisle. Note that this system operates on a Last-In, First-Out (LIFO) basis, as only the most recently loaded pallet is directly accessible.

    Push-back Racking Nested Carts and Rails

    Drive-in and Drive-through Racking

    In this racking system, pallets are supported by a pair of rails specifically designed to match the dimensions of the pallets. These rails enable the forklift mast and forks to access the pallet as it moves along the bay. Loading is performed by driving the forklift into the last available position within the bay. Once in position, the pallet is carefully lowered onto the rails. After loading, the forklift mast is retracted, and the forklift exits the bay. Each bay is dedicated to a single SKU and can hold multiple units deep, making this system suitable for high-density storage with lower selectivity. There are two primary configurations: drive-in and drive-through. In a drive-in system, there is only one access point for both entrance and exit, which supports Last-In, First-Out (LIFO) inventory management. Conversely, a drive-through system features two access points—one for loading and one for unloading—facilitating First-In, First-Out (FIFO) inventory management.

    Drive-through Racking

    Pallet Flow (Gravity Flow) Storage

    This racking design uses roller beds to move pallets into the last available position within a lane. The lane features two openings, one at the front and one at the rear, similar to a drive-through system. Pallets are loaded from the rear and roll towards the front of the lane due to the rearward incline of the lane. Off-loading occurs at the front side of the racks. Like drive-in and drive-through racking systems, pallet flow racks are ideal for high-volume, low-SKU applications. This system supports First-In, First-Out (FIFO) inventory management. Although it offers similar storage density to drive-through racks, it does not achieve the same density as drive-in racks due to the use of two lanes. Additionally, the pallet flow system is less susceptible to damage from forklifts, reducing the risk of structural collapse compared to other racking systems.

    Pallet Flow Racking

    Cantilever Racking

    This type of racking system is ideal for storing long products such as roofing materials, pipes, tubes, and lumber. It features upright columns with cantilever arms extending from one or both sides. The vertical spacing between the arms can be adjusted to accommodate the size and bulkiness of the products, and the angle of the arms can be adjusted to ensure secure load retention. Unlike standard selective racking, cantilever racks do not have front upright frames that obstruct loading, making them particularly suitable for storing long or irregularly shaped items such as appliances and furniture.

    Cantilever Racks

    Carton Flow

    This racking system operates on a principle similar to pallet flow racking. It features two access points: one for loading and another for off-loading. Manual loading and off-loading can be done without the use of forklifts, making it ideal for high-volume piece-pick applications, such as in cold storage and food warehouses. Carton flow lanes can also accommodate non-standard-sized items, enhancing flexibility and efficiency in storage.

    Carton Flow

    Mobile Racking

    This method requires shifting an entire rack assembly sideways to open up an aisle. This shifting is typically done using electric motors, though smaller racks might be moved manually or through mechanical means like handwheels. This system offers high-density storage and great selectivity but requires moving the racks to access stored items, making it ideal for warehouses with minimal traffic.

    Mobile Racking

    High-Bay Racking

    As the name suggests, this type takes advantage of having high bays. They are most suitable for automated distribution centers for high density, high selectivity, and high throughput storage. The racks can be single, double, or in some instances, multi-deep rows. Automatic cranes with telescopic forks or order-picking trucks stabilized by rails and supports move along the aisle. The crane picks up a pallet from the conveyor system and places it on its designated rack. Due to the complexity and high cost of this system, it is only viable for warehousing that hedges profits on efficient storage.

    High-bay Racking

    Chrome Wire Racking

    Chrome wire shelving offers great versatility and affordability while matching the strength of stainless steel. It boasts a sleek appearance and is suitable for storing various items, including trays, cartons, boxes, and storage containers, thanks to its robust durability.

    • Strength - Chrome plated wire shelves can hold up to 800 LBS when the shelves are under four feet tall. A standard four shelf unit can hold up to 3,200 lbs of products while shelves over four feet can hold 600 lbs.
    • Light Reflection and Penetration - Unlike standard gray metal shelving, chrome plated wire reflects light, which can brighten a storage area. Since the shelves are made of wire and not solid, light passes through the shelves to make it easier to identify stored items.
    • Sprinkler Effectiveness - In the case of a fire, the chrome plated wire shelving allows water penetration to the floor, a feature that is positively viewed by fire marshals.
    • Mobility - Chrome plated wire shelving can be turned into mobile shelving by adding casters.

    Multi-Tier Pallet Racks

    Multi-tier pallet racks take advantage of unused space in facilities that have high ceilings. Shelves are placed at different levels with aisles and stairs that make the picking process easier. Multi-tier pallet racks resemble mezzanines in that they take advantage of unused space and have different levels above the floor. The use of multi-tier pallet racks makes it possible to increase storage space while providing direct access to products. The typical use of multi-tier pallet racking is operations that store small items, such as auto parts, pharmaceuticals, and document storage.

    The forms of multi-tier pallet racking are pallet racking, shelving racks, and mezzanines. Of the three, pallet racking is the most common. It allows for palletizing at multiple levels. While multi-tier pallet racks can store palletized products, shelving racks are designed for smaller items arranged in multiple tiers. Mezzanine floors are usually additional work space. In the case of multi-tier racking, areas on a mezzanine can be used for storage racking.

    Multi-Tier Pallet Racks

    Chapter 5: Special Shelving

    Epoxy-coated shelving, available in colors like gray, black, or green, is perfect for damp and humid settings. Certain epoxy shelves come with antimicrobial properties to inhibit bacterial growth, making them particularly suitable for use in the food industry and healthcare environments.

    Automated Storage and Retrieval Systems (ASRS)

    ASRS (Automated Storage and Retrieval Systems) leverage software, computers, and robotics to streamline and enhance the efficiency of handling, storage, and picking processes. These systems can be tailored to accommodate various warehouse sizes and rely on a range of technologies to automate warehousing functions.

    Numerous types of ASRS systems are available, each designed to address different warehousing requirements. The most frequently used systems include:

    • Unit Load ASRS - are used for large cases or pallets including loads that weigh several thousand pounds. They have fixed and movable aisle cranes.
    • Mini-load ASRS - are smaller versions of unit load ASRSs and are used for lighter loads. They have shuttles and cranes designed for narrow aisles.
    • Horizontal Carousels - Horizontal carousels are a form of sorting device used with small parts and products. They can be activated by a computer program or an electronic switch.

      Horizontal Carousel

    • Vertical Carousels - Vertical carousels operate like horizontal carousels and have the same activation mechanisms but complete their function vertically rather than horizontally.

      Vertical Carousel

    • Vertical Lift Modules (VLM) - VLMs place or pick items from trays. They are the most flexible of the automated inventory methods and adjust when the inventory changes. Each tray is capable of holding a ton of parts. VLMs have two columns of trays for picking and placing.
    • Cube Based Storage - Cube based storage is the newest of the automated inventory methods. Items are placed in cubes that have robots that shuffle, sort, and pick bins to be delivered to workstations. Every cube on the cube grid works independently and is connected by a wireless system. Cube based systems are modular, which makes it easier for insertion and replacement of cubes.
    • Shuttles - Robotic shuttles move independently riding on narrow rails to different storage levels. They operate quickly and efficiently handling totes weighing 35 lbs. To 110 lbs. Their speed can be adjusted higher or lower to fit the needs of the warehousing system.

    Instead of carts or roller beds, this system employs remote-controlled shuttles for lifting, lowering, and transporting pallets. The lane length is not constrained by inclines, allowing shuttles to accommodate a large number of pallet positions per lane. This system supports both FIFO (First In, First Out) and LIFO (Last In, First Out) inventory management methods.
