ClarkDietrich Cold-Formed Steel C-Studs (C-Series) Cold-Formed / Light-Gauge C-shaped framing members for axial load-bearing walls, curtain walls, tall interior partitions, floor joists and roof truss assemblies. Residential steel framing members are cost-effective, lightweight, easy-to-handle, and manufactured in conditions that allow strict quality control. When designed properly, the result is solid, non-combustible, and durable. Because steel can be pre-cut to desired lengths and is a stable material, you don't need to sort out defective pieces and can erect a frame faster. Also, steel scrap has value and can be recycled. With steel framing, walls will remain straight and true, preventing callbacks due to nail pops and shrinkage cracks. Steel framing can be designed to meet or exceed governmental energy efficiency standards. In addition, by staying straight and true, the steel framing helps prevent cracks due to shrinkage or warping, thus preventing air leaks that result in a costly loss of energy.
