Import Aluminum External Profile Alloy Joint — Buy in wholesale FOB from Supplier in China

This aluminum external profile alloy joint is a structural connector manufactured by Wj-lean Technology Company Limited in Dongguan, Guangdong province. The component is produced from aluminum alloy with magnesium and silicon as the primary alloying elements, supplied in T3-T8 temper condition to suit varying load requirements. Model reference 28J-1 identifies this specific joint geometry, designed for connecting aluminum tubes and profiles in industrial assembly configurations. The square-profiled body accepts standard aluminum extrusion systems with a manufacturing tolerance of ±1%, ensuring repeatable fit across production batches.

The T3-T8 temper designation covers solution heat-treated alloys that are subsequently cold-worked and naturally or artificially aged. This range allows buyers to specify mechanical properties matched to application stress levels, from light-duty display frameworks to load-bearing machinery structures. The silver finish indicates either mill finish or light anodised surface treatment, standard for industrial aluminum hardware where electrical conductivity and corrosion resistance must be balanced. Guangdong province accounts for a substantial share of China's aluminum extrusion and fabricated metal output, with component suppliers typically serving factory automation, retail fixture, and equipment manufacturing sectors.

Primary applications include assembly line framing, machinery guarding, display and exhibition systems, and modular automation structures where rapid reconfiguration is required. Buyers are typically OEM equipment manufacturers, system integrators, and industrial distributors sourcing connectors for 28 mm or similar metric aluminum tube systems. Trade terms, minimum order quantities, and exact lead times should be confirmed directly with Wj-lean Technology Company Limited, as these transaction details are not stated in the source material. The seven-day delivery reference in supplier documentation may indicate sample or small-batch availability rather than production volume scheduling.

Wj-lean Technology Company Limited operates from No. 3, Lianwei Industrial Road, Dongguan, Guangdong Province, China, postal code 523820. The company holds a Harbor trust tier classification within its marketplace profile. The supplier's response rate is recorded at 0.00% with zero average response hours, indicating either a newly registered account, incomplete engagement metrics, or a profile that has not yet accumulated inquiry data. Buyers should treat communication reliability as unverified and initiate direct contact to assess responsiveness before relying on quoted timelines.

The supplier's product focus centers on aluminum joint hardware for industrial framing systems, specifically targeting the 28 mm tube connector market segment associated with lean manufacturing and modular automation. The brand designation WJ-LEAN suggests positioning toward lean manufacturing infrastructure. No verified export license, ISO certification, or factory audit information is present in the source data. Buyers requiring quality management system documentation or social compliance verification should request these directly from the supplier during initial inquiry.
