Galvanized Steel Coils is also called hot-dip galvanized steel coils
as it is produced by immersing steel in a zinc bath, which requires a
pretreatment process when steel passing through different baths for
preparing the surface zinc coating. First, use chemicals to clean
surface of the steel then another chemical treatment for the steel
coils passing through a bath of melted zinc at temperatures around 460
degree. When finished the products shows smooth and shiny appearance.
To store for a longer period, the hot-dip galvanized coils can be
delivered with a final oil coating, according to the customers demand.
If processed by further cold forming and bending processes, it will
has much better ability.
Where to use:
Galvanized steel coils are widely used in the construction industry,
as raw material for the production of corrugated panels, fencing
products, drywall panel profiles, ventilation systems etc. Recommend
for both outside and inside usage, galvanized steel has a high
resistance to corrosion in different environments, due to a protective
layer of zinc of 100 – 180 grams per square metre.
