Corrosion protection of steel structures
Steel structure buildings usually need anti-corrosion treatment after the completion of construction to protect the steel from corrosion and extend the service life of the building. Common anti-corrosion methods include:
Spraying anti-corrosion coating: the anti-corrosion coating is evenly sprayed on the surface of the steel structure to form a protective film to prevent air and water erosion.
Hot dip galvanizing: the steel structure is immersed in the molten zinc liquid, plated with a layer of zinc protective layer to improve the corrosion resistance of the steel.
Electrogalvanizing: Through an electrochemical reaction, a protective layer of zinc is plated on the surface of the steel to play an anti-corrosion role.
Anti-corrosion coating: Anti-corrosion additives are added during the coating process to improve the corrosion resistance of the coating.
By selecting the appropriate anti-corrosion methods and materials, the steel structure building materials can be effectively protected from the erosion of atmosphere, moisture and chemical substances, and the service life of the building can be extended.
