What is an arched building?
An arched building is a self-supported structure that does not require girders, beams or trusses. This building type can be used to satisfy nearly any building function, including housing, warehousing, storage facilities, maintenance facilities, aircraft hangars, agricultural and livestock housing, commercial facilities, recreational structures and more.

Durability and Resistance to Corrosion
Galvanized steel coils or colored steel coils feature a high corrosion resistance as well as a superior heat reflectivity. It reflects a high percentage of heat and can withstand nearly any weather condition with no surface discoloration. These coils are made from high tensile steel and come in a variety of colors in order to enhance the appearance, life and value of the building. The specially designed seaming machines eliminate the use of fasteners and ensure a 100% leak proof performance of the roof.
