Zinc Dross

Hot-dip galvanising is a process that helps protect steel objects against corrosion. During galvanising, the steel objects acquire a protective zinc coating that renders them corrosion resistant.

The galvaniser immerses pre-treated steel objects ​​in liquid zinc, at a temperature of about 450 degrees Celsius. The zinc reacts with the steel, thereby forming a protective coating. After galvanising, crude zinc ashes and zinc dross are left behind in the galvanising bath.
