A sheet steel surface needs to be prepared as there are several non uniformities and impurities that adheres to the surface which acts as a hindrance for protective coating. Hence the surface is prepared, in order to ensure a good bonding between the metal and the protective coat by various methods like shot blasting, liquid dipping, before final surface coating of sheet steel assembly. Powder Coating allows more protective and decorative layer that increases durability of material. Zinc Plating acts as a barrier and as a sacrificial anode when this barrier is damaged. Zinc is the best ally of steel to combat its natural enemy, corrosion. Epoxy Painting provide optimum protection against abrasion, turbulence, corrosive fluids and extreme temperatures.
