PPGI Coil
PPGI coil (pre-painted galvanized steel coil) is a high-quality metal material that combines performance and aesthetics. Made from a galvanized coil base, it’s roll-coated with an organic coating and then cured by baking. It offers strong corrosion resistance and decorative properties, is bendable and crack-resistant, and offers excellent weather resistance and a rich variety of colors. It’s used in building facades, appliance housings, and other applications. As a professional PPGI coil manufacturer, Wanzhi Steel offers customized coatings, thicknesses, and widths, ensuring you always have durable, cost-effective material solutions.

Recommended Coating Options
The key factors that determine the quality of paint are adhesion, corrosion resistance, UV and weather resistance, hardness and wear resistance, and color uniformity and gloss.
The paint used for color-coated steel plates depends on the environment of the selected resin.
The following table summarizes the characteristics:
| Coating type | Features and performance | Subjective recommendations |
| Polyester coating PE | Outdoor life for 5-10 years, moderate cost. Suitable for places with a mild climate. | High cost-performance ratio, suitable for projects with a limited budget. |
| High durability polyester HDP | It has excellent UV resistance, less fading than PE coating under the same light, and the color is more durable | Suitable for harsh outdoor environments |
| Fluorocarbon coating (PVDF) | It can maintain color stability for more than 15 years in coastal areas or areas with strong UV rays | Suitable for coastal buildings or high UV areas |
| Silicone modified polyester (SMP) | The hardness is usually above 3H, with strong scratch resistance, suitable for environments with frequent friction or heavy use. | Suitable for environments with high wear requirements, such as industrial machinery |
