Hot dip galvanizing is the best protective coating technologyfor steel.A 150-year-old practice, it uses zinc to protect steel from corrosion - providing long life, durability and beauty.It also matches the design and handling characteristics of steel. As galvanizing delivers a predictable,engineered performance, it helps to effectively reduce the cost of asset management by virtually eliminating disruptive maintenance. Hot dip galvanizing also meets all environmental responsibilities with processes that have low wastage, low emission and have high recyclability and reusable properties.About Hot Dip Galvanizing Essentially, hot dip galvanizing utilises zinc to protect steelfrom corrosion.A good understanding of how metal corrodes due to air and moisture, and how it can be protected through hot dip galvanizing technology is important.• Corrosion is caused by the inherent tendency of metals to revert to their original earthly ore-state form when subjected to the environment.• Measuring as big as 12.5M (Length) x 3M (Depth), galvanizer kettles are set at temperatures ranging between 435 °C and 455 °C, where the steel article is immersed in a bath of molten zinc. The zinc forms a metallurgical bond to the steel, creating a series of highly abrasion-resistant zinc-iron alloy layers. It is commonly topped by a layer of impact-resistant pure zinc..• The zinc coating on galvanized steel is uniform inside, outside on the corners and edges. The hot-dip galvanized reinforcing steel bond with concrete is at least as great as the bond of bare steel to concrete.
