Import Aluminum Door Hinge — Buy in wholesale FOB from Supplier in China

Henan Clement Aluminum Co., Ltd manufactures this aluminum door hinge from 6063-T5 alloy, an aluminium-magnesium-silicon alloy that is solution heat-treated and then artificially aged to achieve a stable combination of strength and workability. The T5 designation indicates air quenching during extrusion followed by controlled aging, which produces a yield strength of approximately 145-170 MPa, adequate for hinged doors up to 80-100 kg in typical commercial and residential applications. The hinge is designed for integration with aluminium-framed doors, UPVC door systems, and timber doors where a lightweight, corrosion-resistant pivot is required.

The 6063-T5 temper offers particular advantages for hinge manufacture: excellent extrusion characteristics allow complex hollow sections and knuckle formations with thin walls (typically 2.5-4.0mm), while the T5 condition maintains sufficient malleability for post-extrusion piercing, tapping, and end-machining. Standard industry practice includes anodising to 10-20 microns or applying polyester powder coating for exterior applications. The pin is typically stainless steel AISI 304 or 316 to prevent galvanic corrosion at the aluminium-steel interface, though buyers should confirm the pin material and whether it is removable or fixed. Load-bearing capacity depends on hinge height, leaf thickness, and the number of hinges per door; three hinges are standard for doors exceeding 2.0m in height.

The primary buyers for this product are aluminium window and door fabricators, construction hardware distributors, and building contractors serving residential and light commercial sectors in Asia, Africa, and the Middle East. Henan Clement's location in Xinzheng City, Henan Province, places it within China's central aluminium processing belt with access to raw billet and extrusion expertise. Buyers should confirm hinge dimensions (leaf height, width, thickness, and knuckle diameter), pin material, and whether fire-rated variants are available. Packaging is typically in bulk polybags within export cartons, with palletisation for orders exceeding 500 sets.

Henan Clement Aluminum Co., Ltd is located at No.3 Longhu Road, Longhu Town, Xinzheng City, Henan Province, with postal code 450000. The supplier holds a harbor trust tier classification. The platform records a 0.00% response rate with zero average response hours, indicating no enquiries have been processed through the platform messaging system. The company's stated manufacturing scope extends beyond door hinges to include window and door aluminium profiles, decoration aluminium profiles, heat sink aluminium profiles, glass wall aluminium profiles, transport aluminium profiles, and industrial aluminium profiles, suggesting an extrusion-based operation with diversified product lines.

The supplier's source description emphasises bracket and brace corner products for doors and windows, and notes that colour can be anodised. No information is provided about factory floor area, number of extrusion presses, annual output, export markets served, quality management system certification (such as ISO 9001), or specific product certifications. The company name structure (province + name + industry descriptor) is common among Chinese aluminium extrusion enterprises. Buyers should independently verify production capacity, in-house testing capability (mechanical, metallurgical, and coating), and whether the company operates its own extrusion lines or sources profiles from third parties for secondary machining into hinge components.
