Import Aluminum Coil — Buy in wholesale FOB from Supplier in China

This aluminum coil from Chongqing Guosheng Aluminum Co., Ltd is supplied in aluminum alloy grades 3003 and 5052, two of the most widely specified non-heat-treatable alloys in the rolled aluminum market. Grade 3003 is an Al-Mn alloy with moderate strength and very good corrosion resistance, while 5052 is an Al-Mg alloy with higher strength, better fatigue properties, and superior resistance in marine and salt environments. The supplier offers standard mill finish coils with thickness from 0.2 mm to 3.0 mm, though buyers should confirm exact thickness tolerances and available widths before finalising an order.

In industrial practice, 3003 is typically supplied in H14 or H24 tempers for general forming and bending, whereas 5052 is more commonly drawn in H32 or H34 tempers where greater structural integrity is required. The exact temper designation directly affects yield strength, elongation, and suitability for deep drawing or spinning operations. Surface finish options usually include mill finish, bright finish, or chemically cleaned surfaces depending on downstream coating or adhesive bonding requirements. Standard edge conditioning, whether slit or deburred, should be specified when ordering for automated feed lines.

Construction and roofing contractors represent the largest end-user segment for these coils, followed by automotive heat-shield fabricators, HVAC casing manufacturers, and general sheet-metal workshops. Importers typically procure coils in standard export packaging, wooden pallets with moisture-barrier wrapping, or custom crated configurations for ocean freight. Buyers should verify alloy certification, temper certificates, and whether the supplier provides mill test reports or third-party inspection documentation before committing to shipment.

Chongqing Guosheng Aluminum Co., Ltd operates from Xipeng Innovation Zone in Jiulongpo District, Chongqing 400039, placing it within one of China's major inland manufacturing corridors with direct multimodal links to Yangtze River ports and western rail terminals. The supplier holds a harbor trust tier, which indicates a verified business licence and basic profile completeness on the platform, though its response rate is recorded at 0.00 percent with zero average response hours. This absence of response data means buyers should expect to initiate contact and allow time for manual follow-up rather than rely on rapid quotation turnaround.

The company's listing focuses on alloy grades 3003 and 5052 aluminum coil for construction, roofing, automotive, and manufacturing applications, with thickness range and mill finish as its primary stated specifications. No workforce size, annual turnover, production capacity, client references, or specific quality-system certifications are disclosed in the available profile. Buyers are advised to request a current mill test report, alloy-temper certification, and evidence of compliance with ASTM B209 or equivalent standards directly from the supplier before placing trial orders.
