Electro Galvanizing

Galvanized purpose is to prevent corrosion of iron and steel objects, improve the corrosion resistance and service life of steel, but also make products to increase decorative appearance, steel growth over time will be weathering, water, or soil erosion. Annual domestic corroded steel accounts for almost one-tenth of the whole steel volume, so in order to protect the life of steel or parts thereof, the generally used electro-galvanized steel to be processed.

Since zinc is not easy to change in dry air, and in a wet environment more basic zinc carbonate to produce a film, this film can protect the internal parts without being corrosion damage, even if the zinc layer is destroyed certain factors case, zinc and steel over time will combine to form a micro-battery, leaving the steel substrate becomes cathode protected. Galvanized summary has the following characteristics:
1, good corrosion resistance, combined with meticulous uniform, easy to be corrosive gases or liquids into the interior.
2, due to relatively pure zinc layer, both under acid or alkaline environment is not susceptible to corrosion. Long effective protection steel body.
3, after the chromated form a variety of colors to use, according to the customer to pick a favorite, galvanized beautiful, decorative.
4, zinc coating has good ductility, making all kinds of bending, handling and so will not easily fall hit.
