Roofing Sheet

    PPGL Steel Sheet

    PPGL stands for pre-painted galvalume steel, which is a kind of color-coated steel with GL as substrate. It combines the strength of steel with excellent anti-corrosion of Zn-Al coating. The galvalume coating is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their excellent corrosion resistance, PPGL sheets also have high thermal reflectivity, which makes them heat-resisting.

    Product Detail

    PPGL Steel Sheet

    PPGL is GL steel sheets coated with a colored paint layer.
    Characteristics: PPGL provides enhanced corrosion resistance along with a wide range of color choices. It is suitable for architectural and industrial applications in harsh weather conditions.
    Uses: Frequently used in the production of roofing, wall cladding, oil tanks, refrigeration equipment, and more.

    Advantages of Color Coated Plate

    Custom Colors
    You can choose any RAL color, as well as customize the pattern according to your needs. The beautiful surface makes the color coated board decorative. So it can be directly used in many fields.
    Tough Soating
    Color coated steel plate including PPGL plate PPGI steel, the use of continuous coil coating, the surface luster bright, no cracking, no peeling. In addition, it can keep the color for at least 10 years.
    Excellent Mechanical Properties
    The color coated plate retains the mechanical properties of the base metal, such as tensile strength. In addition, the application of the coating can protect the surface from rust, thereby extending its service life. Studies have shown that the service life of color-coated steel sheets is 50% longer than that of galvanized steel sheets.
    Easy to Use
    Different from the coil, the color coated plate is a kind of finished product. This means that it can be directly used in many industries. Considering its light weight, it is easy to carry and install. In addition, due to its aesthetic appearance, no additional decoration is required. Also, less maintenance is required during the service life.


    Coating Type

    In the coil coating, the durability of the role is the resin and pigment, the most commonly used finish polyester, silicon modified polyester, high durability polyester and polyvinylidene fluoride.
    Polyester PE
    Good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, low cost.
    Silicon Modified Polyester SMP
    The hardness, abrasion resistance and heat resistance of the coating film are good; as well as good external durability and powder resistance, gloss retention, general flexibility and medium cost.
    High Durability Polyester HDP
    Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good film adhesion, rich color, excellent cost performance.
    Polyvinylidene Fluoride PVDF
    Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited color, and high cost.
