What is GI sheet?

 

The full form of GI sheet is galvanized iron sheet. It is a kind of steel sheet that has been coated with zinc to prevent corrosion and prolong its service life.

 

GI steel plate is a composite material of steel and zinc. Galvanized steel plate combines the advantages of the two materials. The composite material has the strength and plasticity of steel and a corrosion-resistant coating. It is widely used in construction, home appliances, automobiles, etc. It has a wide range of uses in industry.

 

Zinc is a chemical element, its chemical symbol is Zn, its atomic number is 30, and it is located in the 4th period and Group IIB of the periodic table of chemical elements.

Zinc has excellent resistance to atmospheric corrosion and can easily form a protective film on the surface at room temperature. Therefore, zinc is most commonly used in the galvanizing industry. It is mainly used for surface coating of steel and steel structural parts (such as galvanized sheets), and is widely used in automobiles, construction, ships, light industry and other industries.

Product categories and features


Classification: According to the type of coating, it is divided into GI (pure zinc coating), GA (zinc-iron alloy coating), 55%Al-Zn (GALVALUME), 5%Al-Zn (zinc-aluminum coating, GALFAN), Aluminizing (plated Aluminum), Zn-Al-Mg (zinc aluminum magnesium coating).


Hot-dip pure zinc products (GI)
Features: Beautiful surface, good corrosion resistance, and good processability.

By adding elements such as lead or antimony to the zinc solution, large and beautiful zinc flowers can be obtained.

 

Hot-dip galvanized alloy products (GA)
Features: The zinc-iron alloy coated steel plate has good paint adhesion, good corrosion resistance and good weldability after painting.


Hot-dip aluminum zinc products (GALVALUME)

Features: Good corrosion resistance, 2-6 times that of hot-dip galvanizing. This is a conclusion drawn from comparing samples with galvanized steel plates after exposing them to different environments for more than 15 years; Good temperature resistance, can be used at 300 It will not discolor when used at ℃. If discoloration is allowed, the use temperature can reach 700℃. Has an excellent heat reflective surface.
