How should we do a good job of anti-corrosion measures for the steel structure?

1. The steel structure should fully consider the overall layout of the building. If there are areas in the building that produce corrosive media, they should be isolated and a layout scheme conducive to natural indoor ventilation should be adopted.

2. The steel structure should be as easy as possible to use, easy to check, brush, paint and not easy to accumulate, water accumulation structural form, when using the open section, the opening should be downward - especially the exposed outdoor parts should be more so.

3. The steel structure adopts members with a small surface area as much as possible.

4. When necessary, the steel structure can use steel with strong corrosion resistance.

Anti-corrosion can use different methods, the same method in the use of many varieties of materials, and performance is different, such as improper selection, not only can not play an effective anti-corrosion role, but will cause economic losses, the choice of anti-corrosion method is related to the following factors:

1. The

nature of the corrosion medium in the environment where the steel structure components are located is well classified

2. The importance of the structure and the position of the components

3. The

degree of surface treatment of components

4. Performance and quality of anti-corrosion measures

5. The steel structure should pay attention to making the sum of the first cost and the maintenance cost during the use period to the minimum

According to these factors, the selection principle of steel structure anti-corrosion method is:

1. It has sufficient corrosion resistance

2. It has good adhesion

3. Easy to construct
