Precision-engineered aluminum doors and architectural fenestration solutions custom-built for high-end residential, commercial, and hospitality developments worldwide.
Established in 2004, Doorreme Aluminum Industry Co., Ltd. operates a premier 123,000 m² smart manufacturing ecosystem in Shishan Town, Foshan—the world's hub for structural aluminum extrusion.
As a vertically integrated OEM/ODM manufacturer, we eliminate intermediary cost layers while asserting strict oversight over profile extrusion, anodizing, powder coating, thermal break assembly, structural glazing, and hardware fitting. Our workforce of over 800 skilled specialists and 50+ senior facade engineers enables architects, property developers, and wholesale distributors to turn complex architectural drawings into structural reality.
Modern architectural demands require fenestration systems that balance maximum daylighting with rigorous energy performance and extreme wind-load capabilities.
Architects are driving demand for minimal frame profiles. Next-generation stacking doors feature ultra-slim vertical interlocks as narrow as 20mm to 25mm. High-tensile 6063-T6 aluminum alloys ensure structural rigidity under wind pressures exceeding DP60 (Design Pressure rating).
To comply with stringent building energy codes (such as NFRC, Title 24, and European CE standards), stacking profiles incorporate multi-cavity PA66GF25 (25% fiberglass reinforced polyamide) thermal barrier strips, reducing overall system U-values to under 1.4 W/m²K.
Barrier-free transition is a major procurement trend. Sub-floor drainage channels equipped with heavy-duty stainless steel (SS304/SS316) tandem rollers allow seamless indoor-outdoor floor integration while providing high-volume water evacuation during hurricane-force rainfalls.
In B2B OEM manufacturing, the longevity of stacking doors depends heavily on raw material purity and protective coatings. Standard aluminum extrusions often use recycled billet stock prone to micro-cracking under stress. At Doorreme, we use 100% primary aluminum ingots extruded into 6063-T5 or T6 profiles with wall thicknesses ranging from 1.6mm for standard residential doors to 3.0mm for heavy-duty commercial multi-slide units.
Surface treatments are customized based on geographic installation requirements:
Navigating global supply chain shifts, labor cost inflation, and evolving green building codes over the next decade.
With ocean freight rates fluctuating and job-site labor costs rising in North America, Europe, and Australia, international contractors are increasingly favoring standardized Knock-Down (KD) modular kits. By shipping precision CNC-machined frame components alongside pre-cut EPDM gaskets and pre-drilled assembly points, freight volume is reduced by up to 65% per container, allowing buyers to maximize shipping efficiency.
Heavy glass panels (often weighing over 250kg per sash due to triple-glazed laminated glass setups) require smooth mechanical assistance. Modern OEM ODM factories are integrating concealed 24V DC brushless motor actuators, magnetic driving systems, and smart sensor anti-pinch safety mechanisms compatible with Crestron, Control4, and KNX home automation networks.
Commercial developers pursuing LEED, BREEAM, or WELL certifications require detailed Environmental Product Declarations (EPDs). Sourcing from factories utilizing low-carbon aluminum smelted with renewable hydro-energy reduces embodied carbon footprint, providing a tangible bidding advantage in public tenders.

Key operational and engineering guidance for importers, developers, and trade buyers.
OEM (Original Equipment Manufacturer) service involves fabricating stacking doors strictly to your provided CAD/BIM architectural drawings and profile dies. ODM (Original Design Manufacturer) service utilizes our established engineering platforms, allowing you to customize sash dimensions, hardware brands, glass builds, colors, and track profiles while relying on our pre-tested structural calculations.
Our products are tested and certified to international standards including AS2047 (Australia), NFRC / AAMA (North America), CSA (Canada), and CE Mark (Europe). We provide third-party laboratory test reports for air infiltration, water penetration resistance, structural wind pressure, and thermal transmittance upon request.
We incorporate integrated sub-head and sub-sill flashing channels with continuous step seals and directional weeping valves. Combined with high-grade EPDM weather gaskets (rather than cheap PVC seals), water is directed away from interior floor lines even during severe pressure differentials.
Production shop drawings are finalized within 3 to 5 business days. Profile extrusion, powder coating, structural assembly, and rigorous factory testing typically take 25 to 35 calendar days depending on batch volume and hardware selection (e.g., custom German Roto or Siegenia hardware may affect lead times).
All products undergo export-grade protective packaging. Aluminum frames are wrapped in anti-scratch protective film and shock-absorbing foam. Glazed units are packed inside fully enclosed fumigated wooden crates or steel-framed A-frames with corner protectors, ensuring zero breakage during containerized transit.
Yes. Our engineering division provides complete structural wind load analysis, shop drawings, and step-by-step 3D installation video manuals. For large-scale commercial developments or hotel projects, senior technical directors can be dispatched on-site to guide local installation teams.
