Steel structure is mainly made of steel structure, with high strength, light weight, fast construction and so on. It is commonly used in low-alloy high-strength steel such as Q345, and is constructed by welding and bolted connection. In the field of plant, it can achieve large span, flexible space layout, strong bearing capacity, but it is necessary to do a good job of fire prevention and rust prevention, good durability under normal environment, and is widely used in the construction industry
