MECHANICAL ZINC COATING IN SHARJAH

In Mechanical Galvanizing a thick coating of zinc provides sacrificial or cathodic protection to the steel fastener. Because zinc is more reactive than iron, the zinc coating "sacrifice" or corrodes first, protecting the steel substrate. The rate of corrosion of zinc is at least 10 times slower than that of steel, thus a thin coating of zinc can protect the steel for a long time.

Mechanical Galvanizing results in a very uniform coating thickness reducing thread fit issues at assembly, making it a preferable coating for structural applications. Not o
