In the contemporary building construction landscape, architecturalfenestration systems have evolved beyond basic thermal barriers into structural, acoustic, and aesthetic facades. As a tier-1 Custom OEM Aluminium Alloy Door Supplier & Exporter, Doorreme Industry Co., Ltd. integrates raw billet metallurgy, precision profile extrusion, thermal break assembly, structural silicone glazing (SSG), and multi-point security hardware into unified, certified fenestration packages.
With global construction codes tightening around thermal transmittance metrics (U-Factors), solar heat gain coefficients (SHGC), and dynamic wind load resistance (up to 5.0 kPa structural pressure), choosing an qualified original equipment manufacturer (OEM) demands a technical evaluation of manufacturing infrastructure, structural calculations, and raw alloy integrity.
Utilizing high-purity architectural aluminium billets offering yield strengths exceeding 170 MPa and tensile strengths up to 205 MPa for high-span glazing support.
Reinforced polyamide thermal break strips minimize thermal bridge effects, enabling system U-values as low as 1.2 W/m²·K (Passive House standard compliant).
Fluoropolymer PVDF and advanced anodizing treatments engineered for coastal environments, passing 3,000-hour salt spray corrosion resistance tests.
Precision-engineered systems fabricated to exact opening specifications, certified under AS2047, NFRC, NAFS, and CSA standards.
For structural engineers, trade procurement agents, and architectural developers, standardized metrics ensure structural integrity under environmental loads. Below is the technical baseline comparison matrix maintained across our custom OEM aluminium door series.

As international carbon tariffs such as the EU's Carbon Border Adjustment Mechanism (CBAM) take effect and urban developments shift toward decarbonization, global buyers are adjusting their procurement criteria. OEM suppliers must align with three macro industrial developments:
Primary aluminium production consumes approximately 14 kWh/kg of electricity. To meet international green building certification benchmarks (LEED v4.1, BREEAM, and DGNB), Doorreme integrates up to 75% post-consumer recycled aluminium billets melt-processed via clean energy sources, reducing embodied carbon footprints from 18 kg CO₂/kg Al down to under 4.0 kg CO₂/kg Al without compromising mechanical yield properties.
Modern architectural design prioritizes maximum daylighting coefficient and minimal visible framework. The engineering challenge involves supporting heavy double and triple insulated glass units (IGUs weighing over 180 kg per leaf) on slim interlocking mullions (as narrow as 20 mm). This requires high-strength 6061-T6 structural inserts, stainless steel track assemblies, and structural silicone glazing (SSG) that transfers dead loads directly to the roller chassis.
Commercial and high-end residential clients increasingly specify IoT-enabled automated door hardware. Future-ready OEM profiles integrate concealed motorized drive tracks, biometric access control modules, magnetic sensor contacts, and multi-point security locking points (up to 6 locking hooks per leaf) that interface directly with KNX, BACnet, or Zigbee smart automation systems.
Direct integration of Revit families and IFC files, permitting seamless digital twin modeling and rapid shop drawing approvals prior to die extrusion.
25-year structural profile warranties paired with 10-year PVDF surface stability guarantees for coastal installations.
Operating out of Foshan, Guangdong—the core of China's aluminium fabrication hub—Doorreme Industry Co., Ltd. spans over 123,000 square meters of state-of-the-art production space. Since 2004, our company has evolved from a regional extrusion workshop into an international exporter serving contractors, real estate developers, and wholesale distributors in over 140 countries.
Our workshop houses automated 2,500-ton extrusion presses, Italian 5-axis CNC machining centers, and automated PVDF powder coating lines. Profile cutting tolerances are kept within ±0.2mm, preventing air infiltration or corner joint misalignment during job-site erection.
Doorreme products are rigorously tested by independent third-party laboratories (Intertek, SGS, and TUV). We maintain active certifications including North American NFRC and NAFS standards, Australian AS2047 / AS1288 compliance, and European CE fenestration ratings.
Clear, definitive answers regarding OEM customization, minimum order quantities (MOQ), global logistics, and technical submittals.
Yes. We offer complete OEM custom extrusion die creation. Once your CAD or STEP files are evaluated by our engineering department, die fabrication takes approximately 10 to 15 days. Sample extrusions are provided along with laboratory tensile and dimension reports for sign-off before full production runs begin.
For tropical and typhoon-prone regions (e.g., Southeast Asia, Caribbean), we specify 6063-T6 or 6061-T6 profiles with heavy wall thickness (2.0mm+) paired with PVDF coatings for UV protection. For frigid climates (e.g., North America, Northern Europe), we mandate multi-chamber PA66-GF25 thermal breaks combined with triple-pane Low-E Argon filled glass to achieve system U-factors below 1.4 W/m²·K.
Our standard production lead time is 25 to 35 days upon final production drawing approval and deposit receipt. MOQ for standard stock profile colors is 50 square meters. For custom profile extrusions or bespoke powder-coat RAL matching, the initial order threshold is 300 square meters or 1.5 metric tons of extruded aluminium alloy.
All units undergo a 5-layer protective packing protocol: 1) Protective anti-scratch film over exposed aluminum, 2) EPDM corner guards, 3) Bubble-wrap wrapping, 4) Moisture-absorbent desiccant packs, and 5) Fully enclosed fumigated OSB plywood crates with steel bands and forklift clearance bases.
Yes. Our technical department provides structural wind-load calculation packets, glass deflection reports, shop drawings, and certified third-party laboratory test reports (NFRC, AS2047, CE) to facilitate smooth municipal permitting and architectural sign-offs.
Submit your project drawings, schedule specs, or BOQ directly to our senior structural engineering team for a comprehensive quotation and shop-drawing review within 24 hours.
