The heavy steel structure we refer to in daily life is a high-strength steel structure with good fire resistance and corrosion resistance. Due to its high strength, good rigidity, high temperature resistance, and wear resistance, it is widely used in fields such as aerospace, automotive manufacturing, and wind power generation.

Heavy steel structures are mainly composed of plates, connectors, and fasteners. The steel plates are usually made of low-carbon steel or alloy steel, and the connecting materials are steel pipes or welded steel pipes; Fasteners generally use bolts, nuts, or rivets; Fasteners also include connecting rib plates, gasket plates, lock nuts, sealing washers, and so on. Due to its reasonable design, convenient installation, and low maintenance costs, the heavy steel structure has been widely welcomed in many engineering applications.

Heavy steel structures have strong compressive strength and tensile strength, and are widely used in industries such as construction, shipbuilding, and bridges. Its main role in application is to comprehensively reduce the damage caused by earthquakes to buildings, increase the seismic performance of buildings, reduce wind load effects as a whole, and prevent capsizing accidents of ships at sea.

Heavy steel structure includes steel pipes, profiles, and steel plates. According to their purpose, they can be steel or wood used for bridges, housing construction. It can also be used as the main load-bearing component of mechanical equipment components. In the industrial field, heavy steel structures are mainly used to make large parts (such as machine parts). For example, engine frames, car bodies, etc. require the use of heavy-duty steel materials for production. In addition, heavy steel structures are widely used in various infrastructure construction projects, such as roads, bridges, power engineering, water conservancy dams, and so on. These construction projects have high quality requirements due to their large scale, high investment, and high technical requirements.

Heavy steel structures have good performance and durability, and can withstand large load forces. Therefore, its application in the construction industry is very extensive.
