1,steel structure


Refers to a structural form that can withstand and transmit loads by means of steel plates and hot-rolled, cold-bent or welded profiles joined by joints. The steel structure system has the advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery and less environmental pollution. Compared with reinforced concrete structures, it has “high, large and light”. The unique advantages of the development of the three aspects, in the global scope, especially in developed countries and regions, steel structures have been rationally and widely applied in the field of construction engineering. The steel structure industry is generally divided into five sub-categories: light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure. The company's current business is mainly concentrated in the first two categories.


2, light steel structure


Mainly made of light H-beam (welding or rolling; variable section or equal section) to form a portal frame, C-type, Z-type cold-formed thin-walled steel for purlins and wall beams, profiled steel or lightweight sandwich panels As a roofing and wall covering structure, it adopts low-rise and multi-layer prefabricated steel structure housing systems assembled with high-strength bolts, ordinary bolts and self-tapping screws.


3,high-rise steel structure


It is mainly a structural system made of steel or steel plate connected or welded into a member and then connected. High-rise steel structures often use steel frame structure, steel frame-support structure, steel frame-concrete core tube (shear wall) structure, etc. The latter is widely used in modern high-rise and super high-rise buildings, and belongs to steel-concrete mixed structure. To make steel and concrete complement each other and give full play to material efficiency.
