Hot-Dip 55% Al-Zn Coated Steel Coils using electric arc furnace materials (GL)

Hot-Dip 55% Al-Zn Coated Steel Coils using electric arc furnace materials (GL) are produced by coating the surface of electric arc furnace hot-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.
