Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value of US$50-100 million and a team of 51-100 professionals, is proud to present our premium 0.12-0.6mm Thickness Pre Coated Galvanized Steel Coil DX51D Z100 PPGI for Roofing. As a reliable supplier serving global markets including North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, we combine advanced production techniques with strict quality control to deliver high-performance PPGI coils that meet the demands of modern roofing applications. Our product offers excellent corrosion resistance, long-lasting color retention, and superior formability, making it an ideal choice for residential, commercial, and industrial roofing projects.
The Pre Coated Galvanized Steel Coil (PPGI) is manufactured using high-quality DX51D hot-dip galvanized steel substrate with a Z100 zinc coating (100g/m² on both sides). The pre-coating process applies a durable paint system—typically polyester, SMP, or PVDF—that provides outstanding weather resistance and UV stability. With thickness ranging from 0.12mm to 0.6mm and customizable widths, this coil can be easily cut, formed, and installed for various roofing profiles. Below are key technical specifications:
| Parameter | Value |
|---|---|
| Thickness | 0.12mm – 0.6mm (tolerance ±0.02mm) |
| Width | 600mm – 1250mm (customizable) |
| Steel Grade | DX51D (per EN 10169/ASTM A653) |
| Zinc Coating | Z100 (100g/m²) – optional Z120, Z180 |
| Paint System | Polyester, SMP, or PVDF (customizable) |
| Color Options | RAL classic colors, metallic, custom colors |
| Coil Inner Diameter | 508mm / 610mm (standard) |
| Coil Weight | 3 – 8 tons per coil (customizable) |
| Surface Finish | Smooth, textured, embossed (optional) |
Key Features and Benefits:
- Outstanding Corrosion Resistance: The Z100 zinc coating combined with a robust paint system provides double protection against rust, even in harsh environments like coastal or industrial areas.
- Excellent Formability: DX51D steel grade ensures easy bending, profiling, and stamping without cracking or peeling of the paint layer, making it suitable for complex roofing profiles.
- Long-Lasting Color Retention: High-quality polyester or PVDF paints resist chalking, fading, and UV degradation, maintaining the building's aesthetic appeal for years.
- Lightweight Yet Strong: With thicknesses as low as 0.12mm, the coil is lightweight yet strong enough to withstand wind loads and snow loads when properly installed.
- Cost-Effective Solution: Pre-coated coils eliminate the need for on-site painting, reducing labor and material costs while speeding up construction.
- Customizable Options: We offer a wide range of colors, paint types, and dimensions to meet specific project requirements.
- Global Standards Compliance: Our products are manufactured under ISO9001 quality management system and meet international standards such as EN 10169 and ASTM A653.
Applications: This PPGI coil is primarily designed for roofing, but it is also widely used for wall cladding, ceiling panels, gutters, downspouts, and other metal building components. Its versatility makes it a popular choice for agricultural buildings, warehouses, prefabricated houses, and modern architectural projects.

Frequently Asked Questions
Q1: What is the difference between PPGI and regular galvanized steel coil?
A: PPGI (Pre-Painted Galvanized Iron) has an additional layer of paint coating applied on top of the galvanized zinc layer. This provides enhanced corrosion resistance, aesthetic appearance, and color options, making it ideal for roofing and cladding without needing post-painting.
Q2: Can this coil be used for roofing in coastal areas?
A: Yes, the combination of Z100 zinc coating and a high-quality paint system (e.g., PVDF) offers excellent protection against salt spray and humidity. For severe coastal environments, we recommend upgrading to a higher zinc coating (e.g., Z180) or a PVDF paint system for extended durability.
Q3: What colors are available?
A: We offer a wide range of RAL colors, including standard shades like red, blue, green, white, and gray. Custom colors can be matched upon request with a minimum order quantity. Please provide your RAL code or color sample.
Q4: Can you provide samples before bulk order?
A: Yes, we can provide small samples (e.g., 20cm x 20cm pieces) to evaluate quality, color, and thickness. The sample cost is negotiable, and we can deduct it from the first order. Please contact our sales team for details.
Q5: What is the minimum order quantity?
A: Our standard MOQ is 1 ton per size and color. However, we are flexible for trial orders—please discuss your requirements with our sales team. We welcome small orders to test the market.
Q6: How long is the delivery time?
A: For standard sizes and colors, delivery is typically 15-20 days after order confirmation. Custom colors or special requirements may take 25-30 days. We keep a stock of popular colors for quick shipment.
Q7: Do you offer warranty on the product?
A: We stand behind the quality of our products. The paint coating and galvanized layer are guaranteed against manufacturing defects. The exact warranty period depends on the paint system and application environment—please consult our technical team for specific details.
Q8: How is the coil packaged for export?
A: Each coil is packed with waterproof paper, steel sheet, and wooden pallets (or customized packaging). The coils are wrapped to prevent damage during transit. We also provide container loading optimization to ensure safe and efficient shipping.
