As a sales representative at Haomei Aluminum deeply rooted in the export market, I firmly believe that the core competitiveness of our aluminum-magnesium-manganese roofing sheets stems from our precise control over alloys, specifications, and properties, and our deep adaptation to export scenarios. Our al-mg-mn roofing sheet projects span North America, the EU, the Middle East, and Southeast Asia, from large convention centers in Romania to industrial plants in Mexico. Its superior quality has made it the preferred roofing material for many international clients.

Alloy ratio is the foundation of the performance of aluminum-magnesium-manganese roofing sheets. We have customized highly adaptable AA3004/3005 standard alloy and 5052 upgraded alloy systems, taking into account the different usage conditions in various regions worldwide. We use AA3004/3005 as the standard alloy system, which is the industry’s optimal solution for roofing applications. The aluminum matrix purity is ≥95.8%, the magnesium content is precisely controlled at 1.0%-1.5%, and the manganese content is 0.8%-1.3%, supplemented with trace amounts of titanium and silicon to optimize the grain structure. For projects requiring high wind pressure and large spans, we offer an upgraded 5052 alloy solution, increasing tensile strength to over 270MPa while maintaining elongation above 15%, meeting the demands of extreme working conditions. Our alloy formula has undergone 12 years of export verification, demonstrating stable performance in the extreme cold of Northern Europe and the high salt spray environment of the Persian Gulf. SGS-certified composition control with a precision of ±0.05% ensures consistent performance across every batch—a quality threshold many competitors struggle to achieve.
The flexibility of specifications directly determines project adaptability and construction efficiency. We have developed a full-specification customization system covering global engineering needs, precisely matching the building standards and construction scenarios of different countries.
– Thickness range: 0.5mm-1.2mm, mainstream 0.7mm/0.8mm, balancing strength and economy, weighing only 1.8-2.2kg per square meter, 60% lighter than color steel;
– Width selection: 300mm-600mm customizable, adaptable to different edge-locking systems, reducing on-site cutting waste;
– Coating solutions: PVDF (fluorocarbon), PE, and SMP three major systems, color library includes 56 international standard colors, supports RAL, NCS, and AAMA2605 customization, weather resistance warranty of 15-20 years.
Our continuous roll forming production line enables mixed-line production of “one order, multiple specifications,” with a delivery cycle 30% faster than the industry average. This makes aluminum roofing sheets particularly suitable for large-scale export projects with multiple sections and specifications, and we have already served airport, high-speed rail station, and sports stadium projects in over 20 countries.
Addressing the common pain points of global roofing systems, such as leakage, poor weather resistance, and molding difficulties, our aluminum-magnesium-manganese roofing sheets achieve a comprehensive breakthrough with four core characteristics, adapting to various complex working conditions.
The standing seam design eliminates nails and glue, with a mechanical interlocking precision of ±0.1mm. It allows for free sliding during thermal expansion and contraction, completely solving the persistent problem of “nail hole leakage” in traditional roofs. Its wind uplift resistance meets the standard for a Category 16 typhoon (55m/s wind speed).
Double protection with a natural oxide film and coating. It withstands over 5000 hours of salt spray testing, three times that of ordinary color-coated steel sheets. Its service life exceeds 50 years in coastal and industrial corrosive environments.
Elongation ≥15%, it can be cold-bent to an R=500mm arc, suitable for complex roofs such as spherical and curved shapes, requiring no preheating or special equipment.
100% recyclable, with recycling energy consumption only 5% of that used in primary aluminum production, meeting LEED and BREEAM green building certification requirements.
In the fiercely competitive global export market, Haomei’s core advantages lie not only in its products but also in its comprehensive supply chain support and end-to-end service guarantees, making export procurement more worry-free and efficient for its customers.
With its own aluminum rod casting, hot rolling, and cold rolling supply chain, Haomei’s raw material costs are 8-12% lower than those of trading companies, resulting in more competitive FOB export prices while ensuring controllable quality.
All products are certified by ISO9001, CE, FM, and AAMA2605, providing complete material testing reports and certificates of origin, improving customs clearance efficiency by 40%.
Long-term agreements with shipping companies such as Maersk and MSC support various trade terms including CIF, FOB, and DDP. European and North American routes offer an average of 28 days for direct delivery, providing door-to-door one-stop delivery.
Choosing Haomei Aluminum’s aluminum-magnesium-manganese roofing sheets means choosing an export-grade roofing solution that combines quality, cost, and service.
