The low anti-corrosion performance of steel members is a problem that needs to be paid attention to. In order to prevent the members from being easily corroded, various anti-corrosion treatments have appeared. The specific anti-corrosion methods should also be selected according to the actual needs. Steel members can be made of materials with good corrosion resistance, such as galvanized steel, which can be selected according to the actual needs, so as to improve the corrosion resistance of steel structure canopy.
In addition, anti-corrosion paint is also commonly used for steel structure canopy components. After rust removal, steel components shall be painted with a layer of anti-corrosion paint primer within four hours to protect components from secondary corrosion; after the primer is dry and solid, intermediate paint can be painted, and component anti-corrosion paint can be painted in sequence to improve the anti-corrosion performance of components
Secondly, different grades of anti-corrosion paint are used for painting. The selection of anti-corrosion paint is also very important, and we should attach great importance to the quality requirements of the construction process and other aspects.
Because many parts of the steel structure canopy are exposed outdoors for a long time, it is easy to be corroded by various media and produce rust, which leads to a great discount in service life. Therefore, the steel structure canopy will be treated with anti-corrosion treatment in advance when it is processed and manufactured, and it is also necessary to pay attention to the components not to be damaged in the process of transportation or stacking, for example, the components are damaged due to carelessness in the process of transportation or stacking, and the anti-corrosion paint is also required after the structure installation in the later stage, so as to ensure the service life of the steel structure canopy.
