Hot-dip zinc-coated steel strip products

  • POINT01

    Excellent corrosion resistance

    Even if the zinc coating is broken, partly exposing the iron base, the surrounding area is protected from rust by the sacrificial anticorrosion effect of zinc until the area reaches a certain size.

  • POINT02

    Beautifully finished surface

    Zinc is excellent in coating adhesiveness and uniformity. The lubricating effect of zinc makes it easy to mold and provides gracefully finished surface.
