Super- span Steel Structure is used as a major public buildings. Its quality directly affects the safety of buildings and the use of functions. In recent years, as domestic steel new technologies, new techniques' communication and promotion; high-strength profile and high anti-corrosion Coatings are successfully applied to steel building applications in the relatively rapid development. My company in particular, its light steel structure has high strength light weight, good seismic performance, factory automation production line manufacturing and assembly of construction,  installation and short construction period, beautiful appearance and other advantages, which has a wider applications in the large span industrial buildings and warehouses in applications. It undertakes the production of various types of building steel structure production, construction and installation. Technical expertise, reliable quality, timely delivery, reasonable prices, production and installation technology could meet all kinds of the steel structure designs requirements.
