Import Aluminum Alloy Frame Combination Window — Buy in wholesale FOB from Supplier in China

Kunshan Chenfeng Metal Co., Ltd manufactures this Aluminum Alloy Frame Combination Window from 6063-T5 aluminum alloy, a heat-treatable grade valued across the building industry for its excellent extrudability and consistent mechanical properties. The combination format integrates multiple opening styles, fixed glazing, and optional mesh screens within a single frame assembly, a configuration widely adopted in residential villa and commercial facade projects. The thermal break option referenced in the supplier's specification reduces conductive heat transfer, a critical performance metric for energy-efficient building envelopes in temperate and cold climates. Standard export classification falls under HS Code 7610.10, and the supplier notes compliance with ASTM and EN structural specifications for aluminum fenestration.

The 6063-T5 temper delivers a typical tensile strength of 215 MPa and yield strength of 170 MPa, sufficient for multi-story installations without excessive section weight. Wall thickness, surface finish (typically anodised or powder-coated), and gasket specification determine weathertightness and long-term durability in coastal or polluted environments. Thermal break construction employs a polyamide strip between interior and exterior aluminum extrusions, achieving a typical frame U-value reduction of 50 percent compared with non-thermally-broken equivalents. Glazing rebate depth, drainage pathway design, and hardware fixing geometry vary with project structural calculations; the supplier indicates custom dimensions are available to match architect drawings.

Primary buyers include property developers, facade contractors, and renovation specialists targeting markets with mandatory energy codes. The combination window suits new construction, retrofit, and heritage-overcladding where acoustic and thermal performance must improve without altering external appearance. Import sourcing from Kunshan Chenfeng Metal Co., Ltd requires confirmation of exact frame depth, glass specification, and hardware brand, none of which are itemised in the current listing. The factory location in Jiangsu Province, near Shanghai Port, offers containerised export routes to East Asian, Middle Eastern, and European destinations. Buyers should request third-party test reports for air permeability, water tightness, and wind resistance before finalising structural calculations.

Kunshan Chenfeng Metal Co., Ltd is located at No.99 Songnan Road, Qiandeng Town, Kunshan City, Jiangsu Province, China, operating within the Suzhou-Kunshan industrial corridor with established metalworking and extrusion supply chains. The supplier holds a Harbor trust tier on the marketplace, though the response rate is recorded at 0.00 percent with zero average response hours, indicating no messaging activity is captured in the available data. The listing does not state factory size, year of establishment, annual output, or specific export markets served, so buyers should request a company profile and factory audit report directly.

The product focus is architectural aluminum systems, specifically combination windows for residential and commercial export. No certifications, patent holdings, or client references are provided in the source data. The address places the facility approximately 50 kilometres from Shanghai Port, a logistical advantage for container shipping, though inland haulage costs and customs clearance arrangements need clarification. Buyers are advised to verify production capacity, quality management system registration, and previous project references before committing to bulk orders.
