JIS G3322 Certified Color Coated Galvanized Steel Coil

Premium Pre-Painted Steel Coil with PVDF/Polyester Coating – Engineered for Long-Term Performance in Demanding Industries

Discover a high-performance pre-painted steel coil that meets stringent Japanese industrial standards, offering exceptional durability and aesthetic appeal. This advanced material features a premium galvanized substrate combined with uniform PVDF or polyester coatings ranging from 20 to 30 micrometers, ensuring superior resistance to corrosion and vibrant color retention over time. With salt spray test results exceeding 500 hours and a ΔE value below 3 after 2,000 hours of QUV exposure, this product delivers proven quality for architectural facades, appliance manufacturing, and automotive components where reliability and visual consistency are critical.

Key attributes include full traceability through mill test certificates, customizable widths (600–1,500 mm), and thicknesses (0.2–1.5 mm), making it adaptable to diverse engineering requirements. Whether you're sourcing colored steel for modern building envelopes, durable roofing systems, or precision-engineered parts, this solution provides both structural integrity and long-term cost efficiency. The coating system is designed not only for beauty but also for resilience—ideal for environments exposed to UV radiation, moisture, temperature fluctuations, and chemical agents.

Available in standard RAL color options, the coil supports seamless integration into global design projects while maintaining compliance with international specifications. Its consistent finish ensures minimal maintenance needs and reduced lifecycle costs—an essential factor for architects, OEMs, and construction firms seeking sustainable materials. Additionally, the product’s compatibility with standard fabrication processes enhances productivity without compromising performance.

For applications requiring enhanced protection beyond conventional Galvanized Steel, consider our Galvalume Steel option—a zinc-aluminum alloy-coated substrate offering up to six times longer service life. It excels in high-temperature environments (up to 315°C / 600°F) and features self-healing properties at cut edges, minimizing rust initiation points. Commonly used in roofing, siding, HVAC units, and automotive body panels, this variant combines strength with environmental adaptability.

Other specialized variants include Aluzinc Steel with AZ150–AZ200 coatings for industrial roofing and solar frame structures; Aluminum Coil/Plate for lightweight, corrosion-resistant solutions in aerospace and heat exchangers; Stainless Steel (304/316/430 grades) for hygienic environments like food processing and marine equipment; and traditional Galvanized Steel with Z60–Z275 coating weights tailored to varying climatic conditions—from coastal zones to arid regions.

Users consistently report satisfaction with the product’s ability to maintain its appearance under extreme weather conditions and resist degradation from pollutants. Many appreciate the ease of installation, consistent surface quality, and the confidence that comes from certified performance metrics such as accelerated weathering tests and corrosion resistance benchmarks. These real-world experiences reinforce the coil’s reputation as a trusted choice among professionals worldwide.

Common questions often revolve around coating longevity, suitability for outdoor use, and customization capabilities. Rest assured, the PVDF-based finish offers a minimum 20-year color warranty when properly installed and maintained. For those concerned about environmental impact, note that the production process adheres to eco-friendly practices, including recyclable materials and low-VOC coatings. In terms of formability, all variants support bending, cutting, welding, and stamping operations without significant loss of coating integrity.
