Galvanized Steel Coils

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 customer 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.

Galvanized Steel Coils

How to protect Galvanized Steel Coils?

  • Oiling–Putting oil on machine can reduce the corrosion of steel plate under wet storage conditions and then it is much more easier to store.  But when oiling, please make sure not damage the degreasing agent zinc layer.
  • Sealing–Put transparent organic thin layer coating on the surface of product can provide add additional protection against corrosion, especially fingerprint resistant. And when forming, this method can improve lubricity and then use the layer as bottom adhesion.
  1. Phosphating– phosphating treatment is fit for various galvanized steel, in addition to the normal cleaning, no further treatment needed for phosphating. Resistance and anticorrosion coating adhesion can improve this process, reducing corrosion of the danger when storage and transportation. After phosphating you can add some suitable lubricant, this method can improve the forming performance of galvanized steel coils.

Note: we will not take any protection methods stated above without getting customer permission.
