Description
Premium Pre-painted Carbon Steel Coils (PPGI/PPGL)
As a leading manufacturer, Baoli Iron Steel specializes in providing high-quality Pre-painted Carbon Steel Coils, also widely known as PPGI (Pre-painted Galvanized Iron) or PPGL (Pre-painted Galvalume Steel). Our coils are a testament to advanced coating technology, combining exceptional aesthetics with superior functional performance. Through a meticulous pre-treatment and continuous coil coating process, each coil receives a uniform, durable paint layer that not only enhances visual appeal but also provides robust protection against corrosion, ensuring extended product lifespan in diverse environments.
Key Features & Advantages:
- Superior Corrosion Resistance: Our multi-layer paint system, applied over a galvanized (zinc-coated) or galvalume (aluminum-zinc alloy-coated) substrate, offers an impenetrable barrier against rust and environmental elements, significantly extending the material’s service life.
- Unrivaled Aesthetic Versatility: Available in an extensive range of RAL, Pantone, and custom colors, with various finishes including smooth, matte, and embossed textures. This flexibility empowers designers and manufacturers to achieve precise visual specifications for their projects.
- Exceptional Durability & Longevity: Engineered to resist fading, chalking, and scratching, our pre-painted coils maintain their vibrant appearance even under prolonged exposure to harsh UV radiation and extreme weather conditions, making them ideal for both indoor and demanding outdoor applications.
- Excellent Formability: The advanced paint systems are designed to withstand various fabrication processes such as bending, roll-forming, stamping, and deep drawing without cracking, peeling, or compromising the coating integrity.
- Cost-Effective & Eco-Friendly: By eliminating the need for post-painting, our coils offer significant cost and time savings. We adhere to strict environmental standards, providing lead-free and recyclable materials.
Technical Specifications:
Substrate Materials:
- Hot-dip Galvanized Steel (GI): ASTM A653, EN 10346 (e.g., DX51D+Z, DX52D+Z), JIS G3302 (SGCC). Zinc coating mass (Z) typically ranging from Z60 to Z275 g/m².
