Hemaokang Steel (Shandong) Co., Ltd., established in 2025, is a professional manufacturer and exporter of high-quality steel products. With an annual export value exceeding US$50 million and a dedicated team of 51–100 employees, we are committed to delivering reliable solutions for the global construction industry. Our PPGI Prepainted Galvanized Steel Coil (0.35mm thickness, 1250mm width, 20 micron top coat, 5 micron back coat) is specifically engineered for building roofing applications, offering superior corrosion resistance, excellent formability, and long-lasting aesthetics. This product combines the strength of galvanized steel with a durable paint finish, making it an ideal choice for roofing, wall cladding, and other architectural projects.

Our PPGI coil is manufactured using advanced continuous coating technology, ensuring uniform paint thickness and consistent color across the entire coil. The 20 micron top coat provides robust protection against UV radiation, weather extremes, and mechanical wear, while the 5 micron back coat enhances anti-corrosion performance on the reverse side. The 0.35mm thickness and 1250mm width are optimized for easy handling, cutting, and profiling, reducing material waste and installation time. Whether you are a roofing contractor, building material distributor, or construction project manager, this product delivers reliable performance and cost efficiency.

Why choose our PPGI coil for your roofing project? The 0.35mm thickness strikes the perfect balance between strength and weight, reducing structural load while maintaining excellent load-bearing capacity. The 1250mm width is a standard size for most roll-forming profiles, ensuring compatibility with existing machinery. The dual-layer coating system (20+5 micron) provides comprehensive protection — the top coat resists fading, chalking, and corrosion, while the back coat prevents rust formation on the underside, especially in humid or coastal environments. Additionally, our coils are produced with strict quality control, including salt spray testing (ASTM B117) for up to 500 hours, ensuring long service life even in harsh conditions.
