Structures in which the members are made of steel and are joined by welding, riveting, or bolting. Because of the high strength of steel, these structures are reliable and require less material than other types of structures.

Steel structures are distinguished by the diversity of their shapes and by their architectural expressiveness. Fabrication and installation of steel structures are realized through industrial methods. The main disadvantage of steel structures is susceptibility to corrosion, which requires that protective measures, such as the application of special coatings and paints, be taken periodically, thereby increasing service costs.
