Product Description

1.GI steel coil description
It is a special type of steel coil used in a number of different applications within fabrication&
manufacturing environments.GI coil is a process that involves coating metals such as steel
and iron with a thin layer of zinc.The pure zinc layer then turns into zinc oxide when it is 
exposed to oxygen, zinc carbonate after exposure to carbon dioxide.


2.GI steel coil technical processing
After cleaning and acid pickling, the steel coil is submerged in melted zinc, a chemical reaction
permanently bonds the zinc. The zinc actually permanently becomes a part of it and successive
layers are a mixture of zinc and iron.GI steel coil is a special type of steel coil used in a number
of different applications within fabrication and manufacturing environments

4.GI steel coil main usage scope:
widely used in the construction industry, as raw material for the production of corrugated panels, 
fencing products, drywall panel profiles, ventilation systems etc. Recommended 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.

5. GI steel coil advantages:
1) Zinc coating has good adhesion 
2) Resistant to corrosive factors 
3) High strength&quality 
4) Strict quality control system
5) Standard export sea-worthy packing
