How to maintain the steel structure?

Steel structure is mainly composed of steel materials, which is one of the main types of building structure. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.


Steel structure must pay attention to protection, especially thin-walled components. Therefore, steel structure is not suitable for buildings in strong corrosive medium. The steel structure shall be thoroughly derusted before painting, and the paint quality and coating thickness shall meet the requirements of relevant specifications.


In the design, it is necessary to avoid dampness and rain leakage of the structure, and the dead angle of inspection and maintenance should be avoided as far as possible. Newly built steel structures are usually repainted at regular intervals.
