The substrate with cold-rolled strip steel, galvanized steel strip (electric galvanized and hot-dipped galvanized), doing pretreatment (skim and chemical treatment) on the surface with the method of the roller coating, coated with a layer or multilayer liquid coating. Then bake and cool the plate.
Regarding the coating, there is a variety of different colors, customarily called color coating steel plate coating steel plate. Again because the coating was conducted before the steel plate forming process, it's called pre-coated steel sheet in foreign countries.
We are involved in delivering a wide series of PPGI color coated steel coil. Our presented range is available in diverse specifications that meet on client's demand.
The productive manufacturing of top-quality products and top choice machine according to your product requirements will be guaranteed by our engineering instruction
The molds will be examined to confirm optimum structure size and provide assistance in manufacturing and modifying tools. We have long-time online serviced by telephone, email, fax, the video for basic setup and repair and Long-term warranty for our machine and free technology support, which brings you a lot of convenience.
There are important nine tests regarding the standard of prepainted galvanized steel coil:
Coating thickness measurement
Coating mirror gloss measurement
Salt spray test
Accelerated climate test
The advantage of our PPGI color coated steel coil:
It has both the mechanical strength and formability of steel sheet, and has good decorative organic materials and corrosion resistance. Coating adhesion is strong but maintains the novel for a long time.
They are widely used in construction, household appliances, furniture, public facilities and transportation and other fields. PPGI color coated steel coil will play an important role in steel material fields.
