Pre-Painted Galvanized Steel Coil (PPGI) and Pre-Painted Galvalume Steel Coil (PPGL) is a kind of building materials, with galvanized sheet and aluzinc sheet as the substrate, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then firing and cooling, finally the palte steel is called pre-painted galvanized steel coil (PPGI) or pre-painted galvalume.

As the layer bears different colors, it is also known as color coated steel sheet. Through the combined use of diverse paints and base substrates, we select colors and material properties that meet the specific needs.
Painting information as following:
Top Paint: PVDF, HDP, SMP, PE(Polyester), PU.
Prepainted Galvanized Steel Coil has many functions like decorative (color ) machinability, weather resistance, scratch resistance, stain resistance, chemical resistance and adhesion resistance.
Primer Paint: Polyurethane, epoxy, PE.
The functions of this layer including machinability, corrosion resistance, adhesion and scratch resistance.
Back Paint: Epoxy, modified polyester.
ROGOSTEEL is a prepainted steel coil supplier and manufacturer in China. We supply all RAL colors and special patterns can be made, such as wood grain, flower print, camouflage, and brick.
We manufacture thickness is 0.13-0.8 mm, width is 600-1250 mm, and PE, SMP, and PVDF painted steel coil to meet customer needs.
Top Finish Coating (PE/HDP/PVDF, etc.), When the thickness is above 20um, it can effectively prevent the damage of ultraviolet rays and harsh environments to the coating.

The top coating is larger than 20μm to prevent the intrusion of corrosive media. Due to the different anti-corrosion mechanisms of primer and finish coating, not only the total coating thickness should be guaranteed, but also the thickness of primer (>5μm) and finish coating (>15μm).
PVDF pre-painted steel coil requires a thicker coating. It provides a longer service life. The requirements for the backside paint coating depend on the application, and the sandwich panel only requires a layer of primer. The formed steel plate requires two coats. The thickness is at least greater than 10 μm.
The protective film is a transparent or colored plastic film coated on the surface of the pre-painted galvanized steel coil. The purpose is to prevent scratches on the painted surface paint during cold roll forming. Our plastic film thickness is 30 microns, 40 microns, 50 microns, 60 microns, and 80 microns.
The metallic coating of color coating for construction is hot-dip galvanized. The greater the thickness of the metallic coating, the better the corrosion resistance.
The thickness of the metallic coating mainly affects the cut corrosion performance of the pre-painted galvanized steel coils, and the influencing factors include the finish coating, primer, substrate thickness, and metallic coating thickness.
We produce pre-painted steel coils for galvanized steel substrates with metallic coating of G40, G60, and G90. Please select the appropriate one according to the use environment.
We mainly use PE, SMP, and PVDF three kinds of coatings to produce PPGI Coil.
Polyester (PE) coating is suitable for ordinary residential roofing, the price is the cheapest, and it cannot withstand harsh environments. Silicone Modified Polyester (SMP) coating contains high weathering and super high weathering paints which can be applied in areas of high heat and cold, humid heat, and extreme cold. Polyvinylidene Difluoride (PVDF) coating has strong corrosion resistance, strong heat resistance, and the highest price. It is used in countries with humid heat, high temperatures, s and more rain.
We work with beckers, Valspar, and Akzo.
Application：
Constructions: Roofing, wall, water fender, warehouse walls, doors, shells etc.
Household appliances: Refrigerator, washer, shower, dust collector etc.
Auto Industry: Car shell, spare parts, oil box, water box etc.
