Since the late 1940’s, A&S Building Systems has been in the metal building product business. Our modular buildings, steel buildings, prefab shelters, and storage buildings are offered only through our Authorized Builder Network with a “team effort” approach. A member of the NCI Building Systems team, A&S has the philosophy of “Real People...Real Products...Real Solutions.” Our Long Bay® Buildings are used for manufacturing, warehousing, distribution, or retail.
