    Surface Treatment of the Galvalume Steel Sheet

    Surface Treatment

    Feature

    Chemical Treatment

    minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface
    retain the bright metallic luster for a long period

    Oil

    minimize the tendency for humid-storage stain

    Chemical Treatment and Oil

    The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations.

    Dry

    must be transported and stored with special precautions to preserve low-humidity conditions.

    Anti-finger print

    minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface
