Steel structure is a structure composed of steel, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and zinc plating are adopted. Welding, bolts or rivets are usually used to connect components or parts. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures rust easily. In general, steel structures should be derusted, galvanized or painted, and maintained regularly.

Heat preservation and energy saving technology Light steel structure In order to ensure the heat preservation effect, the heat preservation materials used in the external walls and roofs of buildings can be used for a long time and can be used for heat preservation. Generally, light steel houses are filled with glass fiber grid cloth between the wall columns, and a layer of thermal insulation material is pasted on the outside of the wall, which effectively isolates the thermal bridge from the wall columns to the external wall panels. Joists between floors are filled with glass fiber to reduce heat transfer through floors; Glass fiber is filled between the wall columns of all interior walls to reduce the heat transfer between walls.
Fire prevention technology One of the most critical problems of light steel structure is the application of fire prevention technology. The fire resistance rating of light steel structure residence is Grade 4. Fire-proof gypsum boards are attached to both sides of the wall and the ceiling of the floor. The common firewall and the residential wall are protected by gypsum boards with a thickness of 25.4 mm (1 inch), which meets the fire protection requirements of 1 hour. In addition, the glass fiber filled between the wall column and the floor joist also plays an active role in fire prevention and heat transfer.
