Prefabricated steel structure refers to the use of steel and hot rolling, cold-formed or welded shapes by connectors can withstand and transfer loads of international popular form of Portal steel frame light steel structure system. Portal frame steel structures housing activity in the domestic technology is mature, users generally accepted, currently the fastest growing as a popular form.
Gate type steel frame steel structure prefabricated houses can be made into large-span, large space, flexible internal layout and use. (Prefabricated steel structure Gate type steel frame system with single-span even up to 80 meters. Multi span can be up to 180 meters span even greater. ) Steel structure prefabricated houses is mainly used in high load bearing constructions.
Used light h steel (welding or rolling; variable section or, section) made door shaped steel frame supports, c type, and Z type cold bent thin-walled steel made purlins and wall beam, pressure type plate or light clip core Board made roofing, and wall surface enclosure structure, used high strength bolt, and General bolt and the since attack screws, connection pieces and sealed material assembled up of door type steel frame steel system. Steel plants on a global scale, particularly in the steel structure construction in developed countries and regions have more reasonable and widely used in the field. Steel structure workshop and can be widely used in industrial plants, purification plant, storage warehouses, supermarkets, Guild Hall.
