1.1 General Introduction
Prefabricated steel structure buildings are pre-designed metal structures widely used in workshops, warehouses, supermarkets, entertainment centers, and other types of buildings. These structures are known for their ease of installation, structural stability, seismic resistance, water resistance, and fire resistance. Due to the high strength grade of steel, steel structure buildings require less raw materials compared to concrete and wood structures, and they possess high fire resistance and strong corrosion resistance.
The main load-bearing components such as steel columns, steel beams, frames, and trusses are connected through welding, bolting, or riveting. Roofs and walls can be made with composite panels, where galvanized metal sheets effectively prevent rust and corrosion, and the use of self-tapping screws ensures tight connections between the panels to prevent leakage. The core materials of composite panels, such as glass fiber and rock wool, have good thermal insulation, heat preservation, and fireproofing properties. Although brick walls can also be used for wall maintenance, their cost is higher than that of galvanized steel roofs and walls. Steel structures have been widely applied in modern construction due to their high strength, light weight, fast construction speed, and strong plasticity.
