Import Aluminum Expanded Panel — Buy in wholesale FOB from Supplier in China

Dong E Blue Sky And Seven Color Building Materials Co., Ltd. produces SEVEN Aluminum Expanded Panel (AEP), an architectural mesh product fabricated from aluminum alloy grades 3003-H18 and 5052-H18. The panels are available in thicknesses of 2.0 mm, 2.5 mm, and 3.0 mm, with standard sheet dimensions of 1250 mm by 2400 mm, and maximum dimensions reaching 2000 mm in width and 4000 mm in length. The unit weight for a 2.0 mm panel is 2.7 kg per square meter. The alloy designation AA 1060 is also referenced in the supplier's general properties. Surface finishes include PVDF coating or anodized treatment.

The manufacturing process involves slitting and stretching solid aluminum sheet to create open diamond or hexagonal mesh patterns with minimal material waste. The 3003 alloy offers good formability and corrosion resistance for interior and moderate exterior applications, while 5052 provides higher strength for more demanding structural uses. The H18 temper indicates full hardening through cold working, delivering increased rigidity. PVDF coating supplies extended color retention and weather resistance compared to conventional polyester paints; anodizing creates a hard, wear-resistant oxide layer integral to the metal surface. Standard industry practice for architectural expanded metal includes specifying the strand width and open area percentage, though these values are not stated in this listing.

SEVEN AEP panels are specified for building facade cladding, ceiling systems, fencing, and industrial screening where controlled ventilation and visual permeability are required. The lightweight characteristic reduces structural loading and simplifies installation compared to solid sheet alternatives. Architects and contractors specify these panels for projects requiring solar shading, airflow management, or security screening without complete visual obstruction. Buyers should confirm the exact alloy, temper, and coating specification with Dong E Blue Sky And Seven Color Building Materials Co., Ltd. before ordering, as the source references multiple alloy grades. The supplier is located in Daqiao Town, Dong E County, Liaocheng, Shandong Province, China.
