Cold-formed steel framing is sheet steel that is formed into shapes and sizes that are similar to what builders are accustomed to seeing in dimensional lumber.
Steel framing members are formed in a process called roll forming by passing sheet steel through a series of rollers to form the bends that make the shape, e.g. the web, flanges, and lips of a stud or C-shape. Because this process is done without heat (also called “cold forming”) the studs and joists are made stronger than the original sheet steel.
Steel framing can lower construction costs.
Warranty call-backs are minimized because steel does not shrink, split, or warp. As a result, there are no nail pops or drywall cracks to fix after the structure is completed.
Consistent quality means that scrap is drastically reduced (2% for steel versus 20% for wood). These savings also translate into lower costs for jobsite culling of wood materials and haul off and disposal of discarded material.
Discounts on builders risk insurance for steel framed structures can result in significant cost savings for builders.
Steel framing is easier to handle because steel studs weigh 1/3 less than wood studs, and can be installed at 24" to 72" on center.
Steel framing offers marketing advantages because consumers recognize steel as a superior framing product for its fundamental characteristics:
- Long term maintenance costs are reduced because steel is resistant to rot, mold, termite and insect infestation.
- Good indoor air quality is promoted because steel does not emit volatile organic compounds.
- Steel is “Green” because it is the most recycled product on the planet. Steel contains a minimum of 25% recycled steel and is 100% recyclable.
- Steel framing has proven performance in high wind and seismic zones. The non-combustibility of steel allows a significant density increase in commercial and multi-family structures, offering building owners with the potential for higher revenue.
