HOT DIP GALVANIZED ( HDG )
Hot Dipped Galvanized (SDG)
SDG briefly; production is the coating process which is done by immersing the finished iron and steel products in the molten zinc bath about 450 degrees. In this way the entire surface of the material, including the enclosed volumes, is completely covered with zinc. The zinc, which has a strong structure, forms metallurgical bond with the steel. Protects itself against corrosion and extends the life of steel.
In contrast to other barrier protection methods, even if there is impact wear on the coated area, the underlying steel is not affected by this because the zinc on the surface of the product continues to function with cathodic protection. In other words, he sacrifices himself to protect the steel.
