China Wholesale Aluminium Hinged Doors Supplier & Exporter

We exclusively utilize 100% primary virgin 6063-T6 or 6061-T6 architectural aluminium alloy billets, strictly complying with ASTM B221 and GB 5237 standards. For exterior hinged residential doors, our profile wall thickness is 2.0mm. For heavy-duty commercial, grand oversized entrances, or hurricane-rated assemblies, we utilize reinforced structural profiles ranging from 2.2mm up to 3.0mm at high-stress hinge-anchoring zones to prevent frame deflection over decades of high-cycle operation.

Our hinged systems are independently laboratory tested and certified by accredited third-party test bodies (such as Intertek and SAI Global). Testing covers structural deflection under positive and negative wind pressures (ASTM E330 / AS 4420.2), air infiltration leakage (ASTM E283 / AS 4420.4), water penetration under dynamic pressure (ASTM E331 / AS 4420.5 up to 600–900 Pa), and overall thermal transmittance U-factors verified under NFRC 100/200 procedures. Full test reports are provided for municipal permitting submittals.

Standard commercial hinged doors typically engage latch bolts along the strike stile only, leaving top, bottom, and hinge-side margins vulnerable to crowbar jemmying and negative wind-load pullout. Our patented Four-Side Six-Point interlocking system engages hardened stainless steel mushroom cams simultaneously across the top head, bottom sill, locking jamb, and hinge-side interlock upon handle rotation. This creates an interlocking envelope certified to European RC3 anti-burglary standards.

Yes. For coastal installations across Southeast Asia, Florida, the Caribbean, and Australia, we treat profiles with high-performance PVDF fluorocarbon coatings (70% Kynar 500 resin) or 25-micron Qualanod architectural anodizing, withstanding over 3,000 hours of continuous neutral salt spray testing (ASTM B117) without blistering or chalking. All hinge fasteners and strike components are specified in marine-grade 316 stainless steel, and glazing can be configured with SentryGlas (SGP) laminated hurricane-impact glass.

For standard extrusion colors (Matte Black, Architectural White, Dark Bronze, Anthracite Grey), our wholesale MOQ starts at 50 m² or combined container volume. For custom extrusion profiles or specialized RAL color powder matches, MOQ is typically 300 m². Standard manufacturing lead time is 25 to 35 business days following final shop drawing and finish sign-off. High-volume 40HQ container orders are scheduled via automated production routing to guarantee steady rolling dispatches.

We employ an export packaging protocol engineered for intermodal container freight: 1) Every profile surface is covered with 0.08mm electrostatic protective film; 2) Sashes and frames are encapsulated in thick pearl cotton foam wrap; 3) Panels are seated on shock-absorbing rubber dunnage inside custom ISPM-15 compliant fumigated solid plywood crates with external galvanized steel angle banding. Crates are pre-balanced with forklift slots to allow safe unloading at jobsites.

Absolutely. In addition to our proprietary patented multi-point lock mechanisms, our CNC profile machining centers are pre-programmed for European standard 16mm hardware gear grooves. We regularly fit German Roto NT, Siegenia Titan, G-U, Sobinco, and Hoppe architectural handles, ensuring seamless hardware integration and local parts availability for global clients.

We back our export products with an industry-leading warranty schedule: 10-year comprehensive structural frame warranty against metallurgical fatigue or joint delamination; 10-to-20-year coating warranty on PVDF and Qualicoat Class 2 finishes against fading, peeling, or chalking; 5-year warranty on multi-point lock gearboxes, hinges, and kinetic mechanisms; and a 10-year hermetic seal failure warranty on insulated glass units.
