Steel arrives at the forming station as a roll of flat zinc-coated steel.
The forming station forms the steel into the desired shapes and sizes (similar to lumber used for framing). The main difference is that each shape is square and true.
Each steel framing member is formed using a process called roll forming which passes the sheet steel through a series of rollers and dies to form the bends that shape the web, flanges, lips, or C-shape required. This heatless process known as "cold forming" results in studs and joists that are much stronger than the original sheet steel.
Walls, trusses, floors, etc. are assembled in the warehouse, clearly labeled, packaged and prepared for shipment to the jobsite.
