The hardness of the alloy layers formed on the steel surface is higher than iron and zinc. This makes galvanized steel more resistant to wear. The rate of formation of the alloy layer is 1 ยต / sec and the thickness increases as the dipping time gets longer.
Thickness of the alloy layer should be approximately 50% of the total coating thickness. Due to the hard and fragile structure of the alloy layer, if the layer thickness is excessive, the coating may break and spill.
In terms of cost, it is understood that hot dip galvanizing is more economical than other applications. A product that is hot dip galvanized can be used for years without any maintenance or repair. For these reasons, the most accurate and economical solution for the protection of iron and steel against corrosion is the hot dip galvanizing method.
