Prefabricated buildings, exploring in depth
Many steel buildings used as offices, houses, and churches use the steel frame building design. Steel pole buildings typically use steel posts and trusses in place of wood. Metal sheathing may then be used for finishing walls and the roof, although wood sidings are often used as well. Steel pole buildings are also often known as pole barns, particularly when they are used for agricultural applications. Steel arch buildings are commonly seen in agricultural and industrial applications.
