Import Aluminum Extrusion Profiles For Windows — Buy in wholesale FOB from Supplier in China

Guangzhou Ruiju E-commerce Co., Ltd. supplies aluminum extrusion profiles for windows manufactured from 6063-T5 aluminum alloy, a heat-treatable grade recognised in ASTM B221 and EN 755 standards for architectural applications. These profiles are designed for thermal-break window systems, combining corrosion resistance with the structural capacity needed in modern facade construction. The 6063-T5 temper delivers a typical tensile strength of 215 MPa and yield strength of 170 MPa, with elongation at break around 8 percent, making it suitable for load-bearing frame members without excessive weight. The supplier lists these profiles in custom lengths with surface options including powder coating and anodizing, though exact stock lengths and colour ranges require direct confirmation.

The 6063 alloy composition typically contains 0.45-0.9 percent magnesium and 0.20-0.60 percent silicon, giving it excellent extrudability and surface finish quality compared to harder alloys like 6061. T5 temper indicates artificial aging after extrusion, a standard treatment that stabilises mechanical properties for dimensional consistency during machining and assembly. Thermal-break configurations typically incorporate polyamide strips of 14.8 mm to 34 mm width between inner and outer aluminum chambers, achieving U-values down to 1.0 W/m²K in complete window systems. Anodizing thicknesses commonly range from 5 to 25 microns (AA10, AA15, AA20 classifications), while powder coating typically meets Qualicoat or GSB standards with 40-80 micron film thickness. The supplier's custom specification references these finishes without stating specific layer thicknesses or warranty periods.

Buyers for these profiles include window fabricators, curtain wall contractors, and property developers targeting residential and commercial construction across Southeast Asia, the Middle East, and Africa. Typical applications span sliding windows, casement systems, fixed glazing, and louvered vents where thermal performance and weather sealing are specified. The supplier indicates availability for construction and renovation projects globally, though importers should confirm minimum order quantities, lead times, and whether technical documentation such as mill test certificates or thermal transmittance calculations are provided. Payment terms, Incoterms, and packaging methods for ocean freight are not stated in the listing and require direct negotiation with Guangzhou Ruiju E-commerce Co., Ltd.

Guangzhou Ruiju E-commerce Co., Ltd. is located at Room 401, Building 9, No 200 Yuangang Road, Tianhe District, Guangzhou, 510000, Guangdong Province, China. The company's trust tier is marked as 'harbor' on the platform, with a response rate of 0.00 percent and an average response time of zero hours, indicating no recorded inquiry responses within the platform's tracking system. This profile does not indicate manufacturing ownership, factory certification, or in-house extrusion capability, suggesting the company may operate as a trading or distribution entity rather than a direct manufacturer.

The listing presents aluminium extrusion profiles for windows without disclosing year of establishment, employee count, annual revenue, named clients, or factory audit documentation. No ISO certificates, quality management systems, or specific production capacity figures are cited. Buyers should verify whether Guangzhou Ruiju E-commerce Co., Ltd. holds direct relationships with extrusion mills, what quality control protocols are in place, and whether the company can provide material test certificates or third-party inspection reports. The absence of response history on this platform means due diligence through direct communication, reference checks, or sample orders becomes essential before committing to volume procurement.
