Detailed Product Descriptions:

The Prepainted Galvalume Steel Sheet leverages a 15% Al-Zn-Si melt plating process to create a nano-dense protective layer that outperforms conventional galvanized steel in both longevity and visual appeal. With its unique "color-locking" technology, this material resists fading, chipping, and abrasion even in harsh environments such as coastal regions or desert climates. Its application spans from photovoltaic-integrated roofing systems to curtain walls of landmark skyscrapers, offering architects and engineers a blend of technical excellence and design flexibility.

The Galvalume Steel introduces a Zn-Al-Si ternary alloy coating engineered at the molecular level for superior oxidation resistance—even at temperatures up to 300°C. The distinctive “zinc flower” crystalline structure enhances adhesion while maintaining excellent formability, making it ideal for stamping complex parts in automotive chassis, home appliance panels, and large-scale steel structures where weight efficiency and mechanical strength are critical.

For cost-sensitive but high-demand applications, Aluzinc Steel offers optimized performance through refined manufacturing techniques. It maintains corrosion resistance more than double that of traditional galvanized products after 2000 hours of neutral salt spray exposure, making it a preferred choice for agricultural greenhouses, container manufacturing, and outdoor signage installations worldwide.

Aluminum Coil, Pipe, and Plate made from aerograde 6061 and 7075 alloys undergo T6 heat treatment to achieve tensile strengths of 310MPa while reducing self-weight by over 40%. This makes them indispensable in marine battery enclosures, rail transit components, and electric vehicle systems—where lightweight, conductivity, and recyclability align with global decarbonization strategies.

Stainless Steel variants—including 304L, 316Ti, and nano-mirror-finished 201 grades—are produced using vacuum refining to minimize impurities below 0.03%, ensuring robust passivation films. These grades excel in medical equipment, food processing facilities, and luxury commercial interiors, delivering biocompatibility, hygiene compliance, and elegant metallic luster without compromising on durability.

Prepainted Steel utilizes a five-coat, five-bake production line capable of precise thickness control and color saturation across diverse climatic zones—from Arctic cold (-50°C) to desert UV exposure (80°C). Certified by AAMA 2605, these sheets enable architects to transform buildings into expressive artworks while guaranteeing long-term performance in demanding environments.
