Hot-Dip Galvanized Steel Coil

High-Performance Coated Steel and Aluminum Solutions for Global Construction and Manufacturing

Explore a comprehensive range of advanced coated steel and Aluminum Products engineered for durability, corrosion resistance, and aesthetic appeal across diverse industries. From architectural cladding to appliance manufacturing, these materials are designed to meet stringent international standards while delivering long-term performance in demanding environments.

Our hot-dip Galvanized Steel features a dense zinc-iron alloy layer formed through immersion in a molten zinc bath at 450°C, offering Z60–Z350 coating weights (60–350 g/m²). This electrochemical protection mechanism ensures superior cathodic protection, making it ideal for outdoor infrastructure components like bridge supports, utility poles, and automotive chassis parts. Compliant with EN ISO 1461 and RoHS directives, this product delivers both environmental sustainability and mechanical stability under bending stress without delamination.

The Galvalume® steel utilizes a continuous hot-dip process to apply an aluminum-zinc-silicon alloy coating, resulting in enhanced corrosion resistance compared to traditional galvanized sheets. Manufactured per ASTM A792 and meeting EN 10346 quality benchmarks, it offers excellent formability and surface finish—perfect for building envelope systems, roofing panels, and white goods applications where weather resilience and visual consistency are critical.

For high-strength, lightweight solutions, our Aluminum Coil, pipe, and plate conform to GB/T 3190 specifications using wrought aluminum alloys. Cold rolling enables precise control over hardness states, while aging treatments produce aerospace-grade strength. When anodized, these materials provide both structural integrity and decorative elegance—ideal for curtain wall systems and modern architectural facades.

Our Stainless Steel products, based on Fe-Cr-Ni alloy systems, develop a passive oxide film that resists chemical attack. Produced according to ASTM A240, they comply with FDA food safety regulations, making them suitable for food processing equipment, pharmaceutical machinery, and pressure vessels operating across extreme temperatures. Solution-treated grades maintain consistent mechanical properties from cryogenic to elevated conditions.

Both Aluzinc and Galvalume Steel leverage the same two-phase plating technology, certified globally for uniformity and adhesion. These materials pass neutral salt spray tests with flying colors, offering reliable protection in coastal climates or industrial zones. Their use in home appliance back panels and roof decking combines corrosion resistance with reduced weight—a key advantage in sustainable design and logistics efficiency.

The prepainted steel line applies durable organic coatings such as polyester and fluoropolymer via roller coating processes aligned with JIS G 3302 standards. These finishes exhibit exceptional impact resistance, scratch hardness, and color retention, ensuring architectural color steel panels and appliance exteriors remain visually appealing even after years of exposure to UV radiation, moisture, and temperature fluctuations.

Engineered for global markets outside China and its territories, these materials support compliance with international construction codes, environmental policies, and end-user expectations for longevity, safety, and aesthetics. Whether you're specifying metal solutions for commercial buildings, industrial facilities, or consumer electronics, our product portfolio delivers proven performance backed by rigorous testing and real-world application data.

Users consistently report improved project lifespans, reduced maintenance costs, and higher satisfaction with surface appearance and dimensional stability. The combination of advanced metallurgy, environmentally conscious production methods, and tailored finishing options makes these products a preferred choice among architects, engineers, and OEM manufacturers worldwide.

Common inquiries often focus on coating thickness variations, compatibility with welding techniques, and long-term weathering behavior. Each material type is supported by technical documentation detailing its corrosion rate in various atmospheres, thermal expansion coefficients, and recommended fastening practices to ensure optimal installation outcomes.
