Import Aluminum Extrusion — Buy in Bulk from Supplier in China

Shanghai Sanyuan Alu supplies aluminum extrusion profiles from Shanghai, China, positioned for industrial manufacturing and fabrication buyers. The source indicates customizable surface finishes, corrosion resistance, and a strong strength-to-weight ratio as core attributes, though no specific alloy designation, dimensional tolerances, or temper grade are listed. Buyers should request the exact alloy series (6061, 6063, or 6082 are common for general extrusion) and temper condition (T4, T5, T6) before finalising any order to ensure compatibility with their application requirements.

The material is described as recyclable and suitable for outdoor use, which points to mill-finish or anodised surface treatments typical of 6063-T5 architectural extrusions, though the supplier does not confirm this. Standard industry practice for such extrusions includes wall thicknesses from 0.8 mm to over 10 mm, cross-sectional circumscribing diameters up to 300 mm, and lengths typically supplied at 6 metres or cut-to-order. Tolerances per GB/T 6892 or EN 755-9 are standard for Chinese export extrusions, with straightness of 0.5 mm per metre typical for precision-grade profiles.

Applications cited span automotive, construction, aerospace, and electronics sectors. Automotive buyers typically require 6061-T6 extrusions with yield strength above 240 MPa; construction buyers often specify 6063-T5 with minimum wall thicknesses and anodised layers of 10-25 microns. The supplier mentions ISO and SGS certifications in promotional text, but buyers must independently verify current certificate scope, validity dates, and accredited product ranges. Shipping terms referenced include FOB and CIF, though port of loading and lead time are not specified in the available data.

Shanghai Sanyuan Alu operates from Room 1308, Block E of Pufa Square, No. 1715 North Zhongshan Road, Shanghai 200061, China. The supplier tier is marked as imported with a harbor trust tier, and both response rate and average response hours register at zero in the available data. This indicates no recorded buyer engagement through the platform, so direct outreach is essential to assess responsiveness and communication practices. The address places the company in a commercial office building rather than a manufacturing facility, suggesting a trading company or sales office model rather than direct extrusion press ownership.

The listing does not disclose production capacity, number of extrusion presses, in-house tooling capability, or quality control equipment. No specific ISO certificate numbers, SGS report references, or factory audit details are provided in the extractable data. Buyers should request a business licence, factory profile, and recent third-party audit report to verify operational scale and capability. The promotional reference to flexible MOQ arrangements lacks any numerical value, so minimum order quantity, sample policy, and production lead time must all be confirmed directly with the supplier before proceeding.
