Joist and Joist Girders

Steel Joists and Joist Girders

Open web steel joists are an engineered, truss-like construction component used to support loads over short and long spans alike. Typically used in non-residential construction, steel joists and joist girders provide an economical system for supporting floors and roofs. All Vulcraft joists and joist girders are designed and manufactured in accordance with the exacting specifications of the Steel Joist Institute.


Steel Deck

Steel decking is used in many applications but is particularly well suited to roofing and flooring. Steel roof and floor decks have long been recognized for their economy because of their light weight and high strength-to-weight ratio. They provide a durable and attractive roof or floor system for fast all-weather construction, and they offer excellent lateral diaphragm action thus reducing the necessity for structural bracing. Vulcraft steel deck products are designed and manufactured in accordance with the exacting specifications of the Steel Deck Institute.
