Steel framed house would normally be built on a reinforced concrete ground floor slab. The ground floor wall panels would then be fastened and held down to the ground floor slab. The second storey floor bearers would then sit on the top of load bearing walls. These bearers would connect and carry the floor joists. The floor joists would in turn carry the floor boards and the wall panels above. The roof trusses would then sit on the wall panels to carry the roof system and roof loads.
There is a misconception by some that cold formed steel (CFS) should only be used for interior framing or non-structural building elements - but that’s not the full extent of its capabilities. Far from it. CFS delivers many advantages in the construction of structural, load bearing walls as well.
Cold formed steel, also known as light gauge steel or LGS, is deployed worldwide for structural framing, in buildings of all sizes and purposes. These include multi-story projects, meeting engineering compliance to local design and building codes and to last as long as any building erected using traditional materials.

Because CFS, with the help of technical software, can be engineered and designed to be load-bearing, and because of its unique physical characteristics, CFS makes for a superior structural framing material.
