Hot Dip Zinc-Coated Steel In Coil (GI)

- Hot Dip Zinc-Coated Steel In Coil (GI) are produced by coating the surface of hot-rolled or cold-rolled steel coils with zinc coating. This process utilizes the principle of the potential difference between zinc and iron to provide corrosion resistance to the steel product. The zinc coating acts as sacrificial protection, corroding first to shield the underlying steel or iron. According to the potential difference principle, when two different metals come into contact, the metal with lower potential will corrode faster, while the one with higher potential will be protected. 

- Due to the zinc coating with sacrificial anode protection mechanism, the product's lifespan is extended, offering excellent characteristics such as weather or corrosion resistance. Additionally, it presents advantages like lower maintenance costs and reduced environmental pollution. 

- Our products comply with the following standards: JIS G 3302\ AS 1397\ EN 10346\ ASTM(M) A653(M)\ GB/T 2518.

- The general service life time of Yieh Phui (China) Hot Dip Zinc-Coated Steel In Coil (GI) is about 10 years or above depend on coating mass.
