cold formed steel construction
does anyone know about the appropriateness and economic viability of doing a three story office block in cold formed steel sections. i believe this is a popular construction method in some parts of the world. i know there are some proprietary systems but here in botswana i would be relying on using standard cold formed channels and angles.
has anyone used this in conjunction with composite steel sheet faced foam panels as insulation and a stressed skin?
