Hot-Dip 55% Al-Zn Coated Green Steel Sheet In Coil (RC-GL)

- Hot-Dip 55% Al-Zn Coated Green Steel Sheet In Coil (RC-GL) are produced by coating the surface of cold-rolled steel coils with 55% Al-Zn coating. This process utilizes the principle of the potential difference between 55% Al-Zn and iron to provide corrosion resistance to the steel product. The 55% Al-Zn 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 55% Al-Zn coating with sacrificial anode protection mechanism, the product's lifespan is extended, offering excellent characteristics such as weather or corrosion resistance, adhesion, and formability. Additionally, it presents advantages like lower maintenance costs and reduced environmental pollution.

- Our products comply with the following standards: JIS G 3321\EN 10346.

- The general service life time of Yieh Phui (China) Hot-Dip 55% Al-Zn Coated Green Steel Sheet In Coil (RC-GL) is about 10 years or above depend on coating mass.
