Why build with Cold-formed steel?
Cold-Formed Steel (also known CFS, Light Gauge Steel & LGS), is one of the most sustainable materials used in modern buildings and is increasingly popular due to environmental factors as well as cost and efficiency.
Named from its application as it is very malleable and does not require any heat to mold in its final form. Instead, the steel is bent into shape by a machine.
North American Specification for the Design of Cold-Formed Steel Structural Members
​
This Standard applies to the design of structural members cold-formed to shape from carbon or low-alloy steel sheet, strip, plate, or bar not more than 1 in. (25.4 mm) in thickness and used for load-carrying purposes in buildings, and structures other than buildings provided allowances are made for dynamic effects.
