Steel

In general, steel framework supports all loads. In this type, all columns, beams and girders in the framed structure are of steel section. Adequate bracing is needed for these structures in order to resist the wind and earthquake forces.

For these structures, fire-proof and other light materials are used for partitions and exterior walls if it is a building. Steel framed structures are capable of sustaining greater load in a given space. In steel framed structures, circular or curved work should be avoided.
