0.4mm Ppgl In Steel Coils Dx51d Ppgi Strip Double Coated Ppgl
PPGI coil, also known as pre-painted steel or color coated steel, are composite materials
formed by applying protective and decorative coatings onto galvanize steel, through continuous
roll coating and baking processes. These products combine structural strength with superior
weather resistance for architectural, home appliance, and transportation applications.
A standard color coated coil consists of multiple functional layers
| Layer | Component | Function |
| Substrate | CR (Cold Rolled), GI (Galvanized), or GL (Galvalume) | Structural support |
| Conversion Layer | Chromated/phosphate treatment | Adhesion promotion |
| Primer | Epoxy/polyester resin | Corrosion protection |
| Topcoat | PE/PVDF/SMP | Color & weather resistance |
Product Classification
By Substrate:
1) Galvanized (GI)
Zinc coating: 40-275g/m²
Ideal for roofing/wall panels
2) Galvalume (GL)
55% Al-Zn alloy coating (AZ30-AZ150)
Superior heat/corrosion resistance
Coating Type
| Coating | Features | Service Life |
| Polyester (PE) | Cost-effective | 7-13 years |
| Silicone Modified Polyester (SMP) | Enhanced UV resistance | 10-15 years |
| PVDF (70% PVDF resin) | Extreme durability | 20-30 years |
| High Durability Polyester (HDP) | Balanced performance | 15-20 years |
Common Applications
3 main categories:
• For buildings and constructions, we provide workshop, agriculture warehouse, residential
precast unit, corrugated roof, wall, rainwater drainage pipe, roller door, light steel roof structure,
folding screen, ceiling, elevator and stairway.
• For transportation, we are able to provide inside decoration of automobile and train, clapboard
and container.
• For electrical application, we are able to provide washing machine, switch cabinet,
instrument cabinet, air conditioning, micro-wave oven and refrigerator etc.
Packages and Loading
Standard seaworthy export packages: 3 layers of packing. Inside is craft paper, Middle is water proof
plastic film and outside GI steel sheet to be covered by steel strips with lock, with inner coil sleeve.
To prevent the rolling, tipping, jumping and sliding of the steel coil in the container four more common phenomena,
The reinforcement materials used are mainly wood strips, wood plugs, wire ropes and auxiliary equipment.
