Are the same foundations and footings that are used when building in concrete suitable for construction with cold-formed steel?
Cold-formed steel is much lighter than concrete. It weighs approximately 5 psf (0.24 kPa) while concrete ranges from 30 to 70 psf (1.45 to 3.35 kPa). In most cases, using cold-formed steel means the amount of concrete used in the foundations can be reduced. Your structural or foundation engineer should be made aware of the loads acting on the concrete so that the foundations can be designed accordingly.
