JIS G3125 SPA-H Weathering Resistant Steel

    SPA-H Steel Specification:
    Thickness: 0.5-20mm
    Width: 100-2000mm
    Length: 100-2000mm

    JIS G3125 SPA-H Introduction:
    SPA-H resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of the metal SPA-H can form a coating of dark brown oxidation, which inhibits deeper penetration, so SPA-H steel saves the cost of need for painting and costly rust-prevention maintenance over the years.
