Each type of steel joist and steel girder are custom engineered for each project. Nucor Corporation, the parent company of Vulcraft, mills the steel sheet in their plants in Indiana and Arkansas from scrap material. They also buy steel sheet from integrated mills that have a much lower recycled content. Vulcraft fabricates the sheet through a cold-rolling process into a full range of metal deck products, such as roof deck, floor deck, composite deck, and cellular deck. Vulcraft encourages specification of uncoated or primed finish on the metal deck.
All steel framing is manufactured with a galvanized coating.
The steel framing system is suitable for use in residential and small commercial projects. They custom engineer the steel studs, joists, and trusses for each project. The framing packages are intended as an alternative to traditional wood framing. Van Port Steel and Supply has a subsidiary, Van Port Homes, that uses the steel framing package for at least half of the homes they build. The high cost and low quality of wood studs in today's marketplace make steel framing increasingly attractive as an alternative.
