    Advantage:

    1.Anticorrosion durability

    The color coated plate has the effect of mirror coating. When it is added to the pressure roller in the production process of color plate, the protective film is more closely attached to the plate surface, which not only does not affect the bending and other processing procedures, but also can protect the plate surface from damage in the process of processing and assembly. The surface adhesion is stronger, and the durability is better, and there will be no shelling, cracking and cracking after long-term use The defects such as spalling and other powder sprayed plates are easy to appear, and can be strictly controlled according to the requirements of customers.

    2.Executive standard

    The company has passed IS09001, gbat24001, gba28001 quality certification, established and improved a set of quality assurance system. Under a complete set of quality assurance system, there are complete procedures from order to production and delivery, and the following standards are strictly implemented.

    • GB / T 12754 color coated steel plate and strip
    • JIS g3312 "pre coated hot dip galvanized steel sheet and strip"
    • En10169-1 continuous organic coated (coil coated) steel sheet products Part 1: general information (definitions, materials, tolerances, test methods)
    • En10169-2 "continuous organic coating (roll coating) steel plate products" part 2: building external products
    • ASTM a755 "pre coated steel plates for exterior use in buildings based on hot-dip metal coated plates and produced by roll coating process"

    3.Substrate

    The color coated substrate mainly includes cold rolled sheet, galvanized sheet and aluminized zinc sheet. The surface of cold-rolled substrate color coated sheet is smooth and has good processing performance, which is suitable for indoor buildings or household appliances. In addition to the good corrosion resistance of the surface coating, the zinc coating also has a good anti-corrosion effect on the substrate, and the protection of the cutting edge is better than other types of substrates. The coating surface of color coated board is smooth and beautiful; The weight of zinc layer can be determined according to your needs.

     

    The process flow
     Color coated steel plate usually the galvanized steel,GL after surface treatment on their surfaces coated with a certain thickness of the adhesive coating or layer of organic film,after curing,become a color plate,with excellent corrosion resistance,molding,decoration in the building,home appliances,light industry,transportation and other industries widely used as an ideal composite material.
