PPGL Steel Sheet Description
PPGL is GL steel sheets coated with a colored paint layer. Characteristics: PPGL provides enhanced corrosion resistance along with a wide range of color choices. It is suitable for architectural and industrial applications in harsh weather conditions. Uses: Frequently used in the production of roofing, wall cladding, oil tanks, refrigeration equipment, and more.
PPGL stands for pre-painted galvalume steel, which is a kind of color-coated steel with GL as substrate. It combines the strength of steel with excellent anti-corrosion of Zn-Al coating. The galvalume coating is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their excellent corrosion resistance, PPGL sheets also have high thermal reflectivity, which makes them heat-resisting.
Advantages of Color Coated Plate
- Custom Colors: You can choose any RAL color, as well as customize the pattern according to your needs. The beautiful surface makes the color coated board decorative. So it can be directly used in many fields.
- Tough Coating: The use of continuous coil coating, the surface luster bright, no cracking, no peeling. In addition, it can keep the color for at least 10 years.
- Excellent Mechanical Properties: The color coated plate retains the mechanical properties of the base metal, such as tensile strength. Studies have shown that the service life of color-coated steel sheets is 50% longer than that of galvanized steel sheets.
- Easy to Use: Different from the coil, the color coated plate is a kind of finished product. Considering its light weight, it is easy to carry and install. Also, less maintenance is required during the service life.

Key Features
- Double-layer protection: Hot-dip Al-Zn (galvalume) coating plus organic paint film provides outstanding corrosion resistance.
- Wide color choice: Available in RAL or custom colors with gloss or matte finish for architectural aesthetics.
- Long service life: Excellent weather resistance, suitable for harsh climates and coastal areas.
- Good workability: Can be roll formed, bent, punched and cut without damaging the coating.
- Heat reflection: Reflective surface reduces heat absorption, improving building energy efficiency.
Applications
PPGL steel sheets are mainly used for roofing sheets, wall cladding, sandwich panel facings, prefabricated houses, garage doors, air-conditioning housings, refrigerator panels and various home appliances.
