Hot-dip galvanising is a process in which steel objects are protected against corrosion. During galvanising, a zinc coating is applied to steel to protect it against corrosion.
During hot-dip galvanising, steel is immersed in liquid zinc at a temperature of about 450 degrees Celsius. This creates an alloy of steel and zinc.
After galvanising, crude zinc ashes (zink skimmings) are left behind in the galvanising bath. These are removed after each cycle. Rezinal processes the zinc ashes generated during the hot-dip galvanising of steel structures, steel wire and steel pipes.
