What Are PPGI / PPGL Corrugated Sheets?
- PPGI Corrugated Sheets: Made from galvanized steel substrates with a zinc coating, followed by primer and topcoat layers for color, weather resistance, and additional protection. They offer versatile color options, cost-effective performance, and sacrificial protection at minor scratches and cut edges.
- PPGL Corrugated Sheets: Made from galvalume-coated steel substrates, typically containing 55% aluminum, 43.4% zinc, and 1.6% silicon by coating mass, with primer and topcoat layers for color and added protection. They offer good atmospheric corrosion resistance, while the aluminum-rich metallic coating provides solar reflectivity potential.

PPGI / PPGL Corrugated Sheet Profiles
Wanzhi Group offers PPGI and PPGL corrugated sheets in various profiles, sizes, and specifications. Custom profiles and dimensions are available to meet different roofing, cladding, and construction requirements.

PPGI / PPGL Corrugated Sheets Manufacturing Process
- Raw Material Selection: Select PPGI or PPGL coils based on the required steel grade, thickness, coating, and color.
- Coil Inspection: Check the coil surface, dimensions, and coating condition before processing.
- Decoiling and Feeding: Uncoil the steel strip and feed it into the roll-forming machine.
- Corrugated Roll Forming: Shape the pre-painted steel into the required corrugated profile.
- Cutting to Length: Cut the formed sheets to the specified length.
- Quality Inspection: Check dimensions, profile accuracy, and surface defects.
- Packaging and Delivery: Stack, protect, and pack the finished sheets for shipment.
Color and Patterns of PPGI / PPGL Corrugated Sheets
Color Options
PPGI / PPGL corrugated sheets are available in various colors, including red, blue, white, gray, and green. Customers can choose from RAL colors or request custom colors. In hot, sunny regions, light colors such as white and light gray can reflect more solar radiation and help reduce roof heat gain. In colder regions, darker colors may absorb more solar heat.


Pattern Selection
Wanzhi Group offers patterned color-coated steel sheets in designs such as wood grain, marble, stone, brick, floral, grass, sky, and camouflage. Custom patterns are also available to meet different architectural and decorative requirements.



Paint Coating Options
- PE (Polyester): Cost-effective, with good adhesion, flexibility, and a wide range of colors. Typical service life: 5–10 years.
- SMP (Silicone-Modified Polyester): Offers good abrasion and heat resistance, weatherability, and gloss retention. Typical service life: 10–15 years.
- HDP (High-Durability Polyester): Provides enhanced UV resistance, color retention, outdoor durability, and chalking resistance. Typical service life: 10–15 years.
- PVDF (Polyvinylidene Fluoride): Offers excellent UV resistance, weatherability, color retention, solvent resistance, and stain resistance. Typical service life: 20–25 years or longer; it generally has a higher initial cost.
Advantages of PPGI / PPGL Corrugated Sheets
- Corrosion Resistance: Metallic coatings and paint layers help protect the steel against corrosion.
- Attractive Appearance: Available in various RAL colors, patterns, and surface finishes, with customization options.
- Weather Resistance: Suitable coating systems help resist UV exposure, rain, and fading.
- High Strength and Rigidity: The corrugated profile improves structural rigidity while keeping the sheets relatively lightweight.
- Easy Installation: Lightweight sheets are easy to handle, cut, and install, improving construction efficiency.
- Cost-Effective: Combines durability, appearance, and efficient installation to help control project costs.
- Recyclable Material: The steel substrate can be recycled at the end of the product’s service life, supporting material recovery and reuse.
