Pre painted galvanized steel coil



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.

Pre Painted Galvanized Steel Coils Coating Layer

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.
Primer Coating
Pre Treatment (Chromate Coating)
Plating Layer (Zn, AL, 55%AL+Zn)
Base Metal (Cold Rolled Steel Sheet)
Plating Layer (Zn, AL, 55%AL+Zn, Sn, Cr, etc.)
Pre Treatment (Chromate Coating)
Functional Painting (Epoxy, Polyester )

Coating Thickness Selection

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.

Protective Film

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.

Metallic Coating

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.

PPGI Coil Production Process

Unrolling – Stitching machine – Entrance loop – Pretreatment – Initial coating – Bake – Cool down – Fine coating – Bake – Embossed film – Export loop – Inspection station – Cut – Coiling

In the above process, if the cleaning degreasing process is not handled well, the adhesion of the primer of the color coated plate to the galvanized sheet is not good, and it is easy to cause the topcoat of the color coated steel coil to fall off during the press forming process.

Pre-Painted Galvanized Steel Coils(PPGI Coil) Price

The price of pre-painted galvanized steel coils(PPGI Coil) varies depending on the raw material of steel, the weight of zinc of the galvanized substrate used, the type of coatings used, the thickness of the top coat and back coat, the width and thickness of the steel coil to influence the price.

PPGI Coil Uses

The main uses of pre-painted galvanized steel coils (PPGI coils) are home appliances and construction.

Home appliance uses are mainly side door panels for refrigerators, and shells for air conditioners, freezers, and washing machines. The construction field is more widely used than home appliances.

PPGI coil for construction is used for roofing, guttering, sandwich panels, industrial building facades, cold storage panels, and rolling doors.

Z275, Z150, and Z100 can be used for the pre-painted steel coils. For less demanding environments use Z40 zinc and polyester coatings.
