Hot dip galvanized steel coil production line.

Hot dip galvanizing is one of the methods for chemical and electrochemical protection of steel and cast iron materials.

Galvanized anti-corrosion principle, in the humid air, in contains carbon dioxide and water containing oxidation, galvanized layer surface will be covered a layer of mainly composed of alkaline zinc carbonate type white, because the galvanized layer in hot galvanizing production line potential than steel pieces of basic potential (potential value of zinc - 0 -. 76 v, the potential value of the iron - 0.43 v) is low, so in the process of hot galvanizing production line production when form a galvanic coating and the magnesium substrate, zinc steel base erosion and protected, this way of protection is often referred to as electrochemical protection.
