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

Davin International Co., Ltd. supplies aluminum extrusion profiles from Jiangsu Province, China, manufactured in 6063 and 6061 alloy grades with an annual production capacity of 200,000 metric tonnes. The profiles are exported to Germany, Italy, Russia, and the UK, serving construction and industrial markets. Standard packaging is 40 pieces per box. The supplier claims potential purchasing cost reductions of 20 to 40 percent compared to alternative sources, though buyers should verify this independently.

The 6063 alloy is standard for architectural extrusions, offering good surface finish and corrosion resistance for anodizing, while 6061 provides higher strength for structural applications. Typical temper for 6063 in curtain wall and window systems is T5, with T6 available where greater strength is required. Standard mill finish is common, though anodized and powder-coated surfaces can be specified. Typical dimensional tolerances follow GB/T 5237 for Chinese extrusions or EN 755 for European markets, depending on the end application. Wall thicknesses typically range from 0.8 mm to 4.0 mm for standard architectural sections, with larger industrial profiles available to order.

Primary applications include aluminum composite panel mounting systems, curtain wall framing, window and door assemblies, and architectural trim. Buyers are typically facade contractors, window fabricators, and building material distributors. The supplier operates from Jiangyin, a major aluminium processing hub in Jiangsu Province, with established export logistics to European markets. Trade terms, lead times, and exact minimum order quantities should be confirmed directly with Davin International Co., Ltd., as these are not stated in the listing data.

Davin International Co., Ltd. is located at #1201, 12F Mingdu International Building, Jiangyin 214431, Jiangsu Province, China. The company is classified as an imported-tier supplier with a harbor trust tier. The response rate is recorded at 0.00 percent with an average response time of zero hours, which indicates that direct communication may be unreliable and buyers should use multiple contact channels. The listing does not state any verified certifications, factory audits, or third-party quality accreditations.

The supplier profile emphasizes large-scale production capacity rather than specialisation or technical differentiation. No information is provided about in-house die design, extrusion press tonnage, ageing oven capacity, or surface treatment lines. The claimed 20 to 40 percent cost reduction is not substantiated with comparative data. Buyers should request factory verification, sample profiles with mill test certificates, and reference projects before committing to volume orders. The Jiangyin location places the supplier within China's dense aluminium extrusion cluster, which offers logistics advantages but also requires careful supplier qualification due to the high density of competitors with variable quality levels.
