Product Description
EN 10346 DX51D DX52D DX53D S250GD S355GD S550GD Continuously Hot DIP Coated Steel Flat Product Galvanized Steel Coil
Hot Dip Galvanizing Process
Hot dip galvanizing involves pickling steel to remove surface iron oxide, followed by cleaning with ammonium chloride or zinc chloride solutions, and then immersion in a hot dip plating tank. The molten zinc reacts with the iron matrix to form an alloy layer that bonds the substrate to the coating. This process is widely used in construction, appliances, automotive, and power industries.

Advantages of Hot Dip Galvanized Steel
- Complete steel surface protection with zinc coating that corrodes at 1/17 to 1/18 the rate of steel, providing exceptional corrosion resistance
- High hardness zinc layer resists impact and wear, with sacrificial anode protection that continues to safeguard steel even if the coating is damaged
