There are three cases of steel pipe anti-corrosion treatment:
1) If it is used in a general warehouse or canopy or workshop, it is not required to be treated with antiseptic treatment;
2) If used in chemical workshops or in workshops or other structures with corrosive contact, anti-corrosion treatment is required;
3) There are special requirements for steel pipes;


The steel pipe anti-corrosion quota can be installed as follows
1, Enhance the adhesion of the topcoat to the substrate to prevent the coating from penetrating too much into the substrate.
2, anti-alkali. The enclosed base alkali penetrates into the coating to reduce erosion of the topcoat.
3, Anti-rust, to prevent the corrosion of the top paint after the iron products in the base layer are rusted. In addition, the use of a primer can also enhance the texture of the system, save the amount of topcoat and shorten the construction time. Direct construction without primer will affect the appearance and texture of the paint film, and may also cause problems such as chalking. Metal coating without primer can not achieve effective rust prevention.
