HPHT introduces specialized 3004/3005 alloy Color-Coated Aluminum Coils engineered for large-span public infrastructure projects.

Expanding its product portfolio into heavy-duty architectural applications, Zhengzhou HPHT Industrial Co., Ltd. (HPHT) has launched a specialized line of 3004 and 3005 aluminum-magnesium-manganese (Al-Mg-Mn) alloy color-coated coils. Engineered specifically for standing seam metal roofing systems, this new product line targets demanding structural applications, marking a practical technical advance in high-strength prepainted metal manufacturing.

Developed to meet the structural demands of large-span public infrastructure—such as sports stadiums, airport terminals, and high-speed railway hubs—the 3004/3005 series combines high tensile strength with excellent tear resistance during complex mechanical forming. Combined with durable surface coatings, these coils provide essential structural stability, weatherability, and corrosion resistance needed for exposed, wide-span roof structures subjected to high wind loads and weather variations.

By targeting large-scale public architecture and engineering sectors, this product expansion highlights HPHT’s manufacturing capabilities in heavy-duty industrial materials. Providing high-performance Al-Mg-Mn prepainted coils allows contractors and project designers to specify reliable, structurally sound metal roofing solutions built for long-term operational performance.

Looking to the future, we at HPHT are dedicated to supplying robust material foundations for major construction endeavors. Moving into complex roofing substrates allows us to serve increasingly demanding architectural specifications, driving our commitment to supply reliable, high-load aluminum products for landmark public works.
