Explore our export-ready, high-performance aluminum window and door assemblies engineered for residential villas, commercial towers, and multi-family developments.
Navigating global building material procurement requires selecting an OEM/ODM partner with undeniable technical capability, rigorous quality management systems, and transparent structural verification protocols. Based in Foshan, China—the epicenter of global architectural aluminum profile extrusion—Doorreme Aluminum Industry Co., Ltd. operates a modernized 123,000 m² manufacturing plant equipped with automated German and Italian fabrication machinery.
Since 2004, Doorreme has operated with a singular operational core: "Better Service, More Value." Serving real estate developers, facade engineering contractors, structural architects, and regional window distributors across North America, South America, Australia, the Middle East, Southeast Asia, and Europe, our facility maintains complete control over the entire production chain—from raw 6063-T5/T6 billet extrusion to multi-cavity thermal break insertion, automated glass unitizing, surface powder coating, and structural load testing.
B2B Procurement Advantage: Unlike standard trading entities, Doorreme provides direct structural silicone glazing (SSG) calculations, wind pressure simulation analysis (ASTM E330 / AS2047 compliant), and shop-ready shop drawings pre-approved for local municipality permitting.
Precision-milled 6063-T5/T6 primary aluminum profiles with profile wall thicknesses up to 2.0mm for windows and 3.0mm for high-span structural curtain walls, utilizing multi-axis Italian CNC machining centers.
High-performance Technoform PA66 GF25 (25% fiberglass reinforced) thermal break struts inserted into profile cavities to effectively sever thermal conduction and minimize condensation risks in harsh climates.
Autonomous double and triple insulated glass unit (IGU) assembly featuring warm-edge spacers, Low-E solar control coatings (PPG/Saint-Gobain glass options), Argon gas filling, and structural silicone sealing.
System windows differ fundamentally from traditional fabricated aluminum windows. While standard windows rely on localized profile cutting and manually fitted hardware, a true System Window is a holistically engineered fenestration system where profiles, thermal breaks, EPDM gasket sealing systems, drainage tracks, and multipoint hardware interact seamlessly under tested thermal, acoustic, and structural performance parameters.
Architects, facade consultants, and general contractors can utilize the matrix below to evaluate performance parameters across typical fenestration configurations when specifying structural packages for overseas projects.
| System Category | Profile Spec & Alloy | Glass Configuration | Thermal Transmittance (U-Value) | Wind Pressure Resistance | Target Application |
|---|---|---|---|---|---|
| Thermal Break Casement Window | 1.4mm - 2.0mm (6063-T5) PA66 GF25 Strut |
5mm Low-E + 12A + 5mm Tempered | 1.2 - 1.6 W/m²K | Class 8 (up to 5.0 kPa) | Luxury Villas, High-Rise Residential |
| Narrow-Frame Heavy Sliding Door | 2.0mm - 3.0mm (6063-T6) Hidden Track System |
6mm + 20A + 6mm Toughened | 1.8 - 2.2 W/m²K | Class 7 (up to 4.5 kPa) | Patio Doors, Beach Resorts, Balconies |
| Unitized Glass Curtain Wall | 3.0mm - 5.0mm (6063-T6) Structural Mullion |
6mm Low-E + 16Ar + 6mm Laminated | 1.0 - 1.4 W/m²K | Super Typhoon Rated (6.0+ kPa) | Commercial Office Towers, Hotels |
| Standard Aluminum Sliding Window | 1.2mm - 1.4mm Non-Thermal / Thermal | 4mm + 12A + 4mm Double Tempered | 2.4 - 3.0 W/m²K | Class 5 (3.0 kPa) | Multi-Family Apartments, Commercial |
As global construction demands accelerate toward decarbonization, climate resilience, and standardized off-site construction, B2B procurement strategies for aluminum system windows and curtain walls are shifting rapidly:
International developers increasingly require Environmental Product Declarations (EPDs). Sourcing certified low-carbon recycled aluminum profiles reduced by green hydro-powered smelting lowers embodied carbon scores significantly for LEED and BREEAM certifications.
To overcome escalating on-site labor costs overseas, buyers are opting for factory-assembled, fully unitized curtain wall units and pre-glazed frame systems. Factory-controlled sealing ensures zero water leakage and speeds up job-site installation by up to 60%.
Fenestration systems now embed motorized chain actuators, concealed magnetic lock gear, and smart home sensor interfaces for automated wind/rain closure, smoke evacuation systems, and HVAC-linked energy optimization.
Below are authoritative responses to the most critical technical and logistical questions asked by overseas project managers, procurement directors, and importers.
Yes. Every order is fully custom-engineered. Once you submit project floor plans, window elevation schedules, or CAD drawings, our technical engineering office produces 2D/3D shop drawings showing exact structural profile cuts, anchorage points, glass build-ups, and drainage details. Production begins strictly after your final sign-off.
Our products are engineered and tested to comply with international standards, including NFRC (National Fenestration Rating Council) energy ratings, CSA standards for the Canadian market, AS2047 / AS1288 for Australia, and European CE benchmarks for air permeability, water tightness, and structural wind load performance.
We supply top-tier German hardware brands such as German Roto, Siegenia, and Hoppe for high-end project specifications requiring heavy sash loading capacity, alongside premium Chinese hardware brands (Hoppo, Kin Long) that balance durability with cost efficiency. Multi-point locking mechanisms come standard across casement and sliding series.
We implement a robust export packaging protocol: aluminum frames are wrapped in protective PE film, edge-protected with corner foam, and bundled. Glass units are packed inside fully enclosed fumigation-free solid plywood crates lined with foam buffers and desiccants, maintaining 0% breakage rates over thousands of overseas shipments.
For custom commercial and residential project packages, our flexible minimum order starting threshold is typically 50 m². Standard manufacturing lead time is 25–35 days from finalized shop drawing approval and deposit receipt, depending on profile powder coating colors and specialized glass coating lead times.
Yes. For major commercial developments or complex curtain wall installations (such as our 14,000 m² Ventura Mall project), our structural engineers provide complete installation sequence manuals, structural calculation reports, and can dispatch senior technical directors to the job site to supervise assembly and alignment.
Send your project drawings, window schedules, or specs directly to Doorreme's engineering team for instant technical consultation, structural analysis, and factory-direct wholesale pricing.
