For more than 100 years, hot dip galvanized steel has been utilized extensively to combat corrosion in major industrial environments including petrochemical, transportation, and public utilities.

The hot-dip galvanized steel is more corrosion resistant than bare iron and steel, similar to steel, zinc corrodes when exposed to the atmosphere, however, zinc corrodes at a rate approximately 1/30 of that for steel.

Different Types of Hot Dip Galvanized Steel Sheet (GI Sheet):

We are able to make galvanized sheet to further processing, such as embossed sheet metal, checker steel sheet, perforated steel metal, corrugated roof sheet, and prepainted galvanized steel sheet. We provide various patterns for those different types. Please check the metal sheet types's table below. All of our metal sheet types are custom-manufactured. 

The GALVANIZED STEEL SHEET PRODUCTS forming process consists of three basic steps: surface preparation, galvanizing and inspection.

Surface preparation consists of three steps: degreasing, acid pickling and fluxing.

Galvanizing is completely immersed in a bath of molten zinc.

A variety of simple physical and laboratory tests may be performed to determine thickness,uniformity,adherence, and appearance.
