Products Definition

The GI sheet is an acronym for the first letter of the Galvanized Iron Sheet, which is derived from Western countries. In many developing countries such as China and Africa, it is called galvanized steel. Since the demand for galvanized steel sheets in African countries is mostly the roof of built houses, and the industry in Africa is underdeveloped, they will purchase processed corrugated steel sheets, so they will also be called GC Sheet (Galvanized Corrugated Steel Sheet).

Different zinc Spangle surfaces

GI sheet means the cold rolled strip or hot rolled pickled steel strip is immersed in the zinc pot in the continuous hot galvanizing production line and the zinc is no less than 99% in all elements. The width of hot dipped galvanized steel coil is no less than 600 mm in this production line.

Due to the difference in lead content and production process, we can provide customers with different zinc flower steel plates. It is obtained by adjusting the chemical composition of the zinc liquid and it is  without visible zinc pattern and uniform surface.

Zinc coating in Small Spangle

The zinc grains are artificially restricted to form as small as possible during the solidification process.

Zinc coating in normal and regular Spangle

The zinc coating is formed by free growth of zinc grains during the normal solidification process.

Zinc coating in non Spangle

Zinc coating

1、The mini zinc coating is 20g/m2 and max zinc coating is 275g/m2.

2、Finishing

Finishing is a kind of small changing the shape on the cold roll to improve the appearance of galvanized steel sheets or suitable for decorative coatings To improve the appearance of galvanized steel sheets or suitable for decorative coatings, so as to minimum the phenomenon of a fold produce.

3、Non zinc coating: obtained by adjusting the chemical composition of the bath without visible visible zinc pattern and uniform surface.

4、The resulting coating.

Poor thickness coating: the two sides of hot-dip galvanized steel require different zinc coating weight.

Finishing: finishing is one of the following and several purposes, and a small deformation of the galvanized steel cold rolling.

To improve the appearance of galvanized steel sheets or suitable for decorative coatings, so as to produce slipping lines (lends lines) when finished parts are processed.

A temporary reduction of the phenomenon of a fold to a minimum.

Tensile strain marks: the slip line and "orange" on the surface of steel plate or steel strip caused by aging.

Subcutaneous "and so on" and so on.

Passivation treatment: a chemical treatment for zinc coating. Can reduce the product during transport and storage due to humidity

Corrosion (Bai Xiu) is the most common surface treatment for zinc plating except for the surface finish, including general passivation.

And environmental passivation. Environmentally friendly passivated galvanized sheet can meet the requirements of the EU ROHS environmental protection act.

Fingerprint resistant treatment: a chemical treatment for zinc coating. Apply transparent organic coating on the surface of galvanized sheet
