    Zero spangle Galvanized Steel Sheet in Coils Introductions


    Hardness: soft (normal), hard, full hard
    Zinc coating: 30-275 G /M², or on request
    Zinc pattern: large zinc pattern, small zinc pattern, no zinc pattern
    Surface finish: fingerprint resistant, chromate, oiled, unoiled

    Zero Spangle Galvanized Steel : In hot dip galvanising, only a certain amount of aluminium is added to the zinc solution and no lead-free, antimony or tin is added to produce a non-bright product.



    Influence of Plating Weight (Thickness) on Corrosion Resistance

    The weight of the coating is the most important guarantee of corrosion resistance. The greater the thickness of the coating, the better the corrosion resistance, which has been proved by many accelerated tests and exposure tests. The thickness of the galvanised layer usually refers to the thickness of both sides, under normal circumstances, the commonly used galvanised layer on the market are double-sided equal thickness hot-dip galvanised.

    Classification of zinc spangle

    Large / Big zinc spangle (regular spangle): zinc spangle formed by free growth of zinc crystals in the normal solidification process after hot dip plating of steel plates in conditions where the zinc solution contains antimony or lead.

    Minimum zinc spangle : because of the control of the growth of zinc flower crystallisation, so the surface grain structure is fine; because of the surface uniformity, so the surface quality after painting is excellent; paintability is better than conventional zinc flower.

    No zinc spangle (zero zinc spangle): because the growth of zinc particles is completely controlled during the molten zinc fixing process, it is difficult to see zinc spangles with the naked eye; because the surface is uniform, the surface quality after painting is excellent.

    Skin passed zinc spangle: the molten zinc is cured and then smoothed to obtain an extremely smooth surface; because the surface is smooth, the surface quality after painting is excellent.
