Continuous Hot-Dip Galvanized Steel Coil

High-Performance Coated Steel and Aluminum Solutions for Global Industrial Applications

Explore our premium range of advanced metal products engineered for durability, aesthetics, and environmental resilience across diverse sectors. From corrosion-resistant Galvanized Steel to high-strength aluminum coils and Stainless Steel components, each material is manufactured using cutting-edge metallurgical processes that meet international standards such as ASTM A792, EN 10346, JIS G 3302, and ASTM A240. These solutions are ideal for architects, engineers, manufacturers, and procurement specialists seeking reliable, long-lasting materials tailored for global markets outside China, Hong Kong, Macau, and Taiwan.

Our continuous hot-dip galvanized steel features a uniform zinc-iron alloy coating ranging from Z60 to Z275 (60–275 g/m² per side), offering excellent formability with elongation ≥18% and superior weldability due to its low-carbon steel base (C ≤ 0.12%). The automated production line ensures consistent quality, while surface finishes like standard zinc flowers or zinc-free patterns allow customization for both functional and decorative needs. This product excels in infrastructure projects—from bridge railings to utility poles—where weather resistance and mechanical integrity are critical.

The Galvalume® steel combines aluminum, zinc, and silicon into a nanoscale alloy layer through advanced hot-dip technology, forming a dense, metallurgically bonded barrier that resists acid rain, salt spray, and UV degradation. With corrosion resistance several times higher than conventional galvanized steel, it’s widely adopted in building envelope systems, HVAC units, and industrial roofing where longevity and minimal maintenance are essential. Its compliance with ASTM A792 and EN 10346 makes it suitable for harsh coastal environments and extreme climates.

For applications demanding lightweight strength, our Aluminum Coil, pipe, and plate are crafted from high-purity wrought alloys following GB/T 3190 specifications. Cold rolling allows precise control over hardness states—from soft H14 to hard H18—making them ideal for aerospace structures, curtain wall panels, and transportation components. Anodized surfaces not only enhance structural performance but also offer customizable colors and textures, blending functionality with modern architectural design.

Our stainless steel series leverages the Fe-Cr-Ni alloy system, naturally forming a passive oxide film that provides exceptional chemical stability even at temperatures from -196°C to 400°C. Perfect for food-grade equipment compliant with FDA regulations and pressure vessels used in chemical processing, this material maintains mechanical consistency under thermal cycling. Solid solution heat treatment optimizes grain structure, ensuring safe operation in demanding industrial settings.

Additionally, our Aluzinc® steel, which shares the same foundation as Galvalume®, delivers enhanced protection via dual-phase plating technology. Neutral salt spray tests confirm extended corrosion life compared to traditional coatings. It's particularly effective in home appliance back panels and roofing systems where cost-efficiency, weather resistance, and aesthetic appeal must coexist without compromise.

The prepainted steel line utilizes continuous roller coating methods to apply durable organic coatings—including polyester and fluoropolymer-based finishes—onto cold-rolled substrates. Compliant with JIS G 3302, these coatings resist impact, abrasion, and fading, making them perfect for color steel sheets in commercial buildings and appliance exteriors. Whether you need vibrant hues or subtle metallic tones, prepainted steel ensures visual consistency and long-term surface integrity in outdoor installations.

These innovative materials have been trusted by leading manufacturers worldwide—from automotive OEMs adopting lead-free galvanizing processes aligned with RoHS directives to construction firms specifying corrosion-resistant cladding for skyscrapers and industrial facilities. Their proven performance in real-world conditions speaks to their value proposition: reduced lifecycle costs, improved safety, and sustainable engineering outcomes.

Users consistently praise the balance between technical excellence and practical usability. Many report fewer field failures, lower maintenance expenses, and greater design flexibility when integrating these metals into complex assemblies. Architects appreciate the seamless integration of form and function, while engineers commend the predictable behavior during bending, welding, and forming operations.

Common questions often revolve around coating adhesion, long-term durability in marine environments, and compatibility with other materials. Our products undergo rigorous testing—including bend tests, salt spray exposure, and tensile evaluations—to ensure they perform reliably under stress. For those concerned about sustainability, all processes are designed to minimize waste and maximize recyclability, aligning with global green manufacturing goals.
