Overcoming micro-climate thermal bridges, structural deflection, and air-water infiltration in complex overhead fenestration systems.
Contemporary architectural design increasingly demands wide-span glazed roofs, continuous ridge skylights, and custom OEM aluminum skylight structures. As a premier Chinese manufacturer operating out of Foshan's 123,000 m² industrial facility, Doorreme Aluminum Industry Co., Ltd. delivers structural silicone structural glazing (SSG), thermal-break extrusions, and certified impact-resistant skylight systems tailored precisely to architectural shop drawings and regional building codes worldwide.
Aluminum skylight systems are subjected to harsher environmental loads than vertical windows, including direct solar irradiance, thermal expansion stresses, concentrated snow loads, and negative wind uplift pressure.
Our custom OEM aluminum skylights utilize high-tensile 6063-T6 or 6005-T6 architectural aluminum profiles, reinforced with polyamide PA66-GF25 thermal barrier strips. This structure prevents internal moisture condensation while reducing thermal transmittance (U-factors) down to 0.8–1.2 W/m²K in triple-glazed low-E configurations.
The global shift toward net-zero buildings drives high demand for Building-Integrated Photovoltaics (BIPV) embedded within overhead skylights. Future OEM procurement prioritizes thin-film solar glass laminates that generate clean energy while providing optimal solar light control (SHGC < 0.25).
Commercial developers are phasing out external mechanical blinds in favor of smart tinting electrochromic glass. With automated building management system (BMS) integration, OEM skylights automatically adjust light transmission based on daylight availability and sun angle.
Fire safety compliance (EN 12101-2 and NFPA standards) requires skylight systems to double as automated natural smoke and heat exhaust ventilators (SHEVs). Integrated chain actuators linked to fire control panels are becoming standard in modern commercial logistics and atrium designs.
Architects are requesting ultra-narrow frame profiles (< 45mm visible width) and structural glass-to-glass corner joints. This design maximizes natural daylight penetration while maintaining high structural resistance under severe wind pressures.
Global general contractors increasingly mandate Environmental Product Declarations (EPDs). Doorreme utilizes recycled aluminum billets extruded via hydro-powered extrusion lines, significantly lowering the embodied carbon of building envelopes.
20+ Years of Manufacturing Mastery, German Machine Precision, and Full Project Support.
Operating a massive 123,000 m² workshop in Shishan Town, Nanhai District, Foshan, Doorreme houses state-of-the-art German CNC 5-axis machining centers, automatic double-head cutting saws, and automated structural silicone glazing lines.
Every custom OEM aluminum skylight undergoes rigorous factory testing before container loading, including air permeability (ASTM E283), water penetration resistance (ASTM E331), and structural load testing (ASTM E330).

Doorreme's technical engineering department supports overseas projects with structural calculations, 3D BIM/CAD shop drawings, and wind pressure simulation analysis. From the massive Ventura Mall project in Santa Cruz, Bolivia (featuring 4,300 m² of glass skylights and 390 tons of structural framework) to airport office envelopes in Banjul, Gambia, our team provides complete engineering assistance.
Whether you require OEM profile extrusion customization, specific RAL color matching, or project site installation oversight, Doorreme guarantees seamless project execution from concept to delivery.
Direct answers to technical and supply chain questions from commercial buyers, architects, and contractors.
Condensation occurs when warm, humid internal air hits a cold overhead structural profile. Doorreme's aluminum skylight profiles integrate polyamide (PA66-GF25) thermal barrier breaks that isolate the interior and exterior aluminum profiles. Combined with double or triple insulated glass units (IGU) containing warm-edge spacers and argon gas filling, our skylights effectively eliminate internal condensation across temperature differentials exceeding 40°C.
International building safety codes strictly prohibit standard monolithic float glass for overhead applications. Doorreme mandates heat-strengthened or fully tempered laminated glass for the inner pane (e.g., 5mm + 1.52mm PVB/SGP + 5mm). If an extreme impact breaks the outer glass, the tough interlayer holds the fragments intact, preventing dangerous falling glass hazards.
Yes. As an authentic OEM manufacturer with custom extrusion die design capabilities, we can develop exclusive aluminum profile moulds according to your CAD/BIM architectural designs. We verify wall thickness, moment of inertia (Ix, Iy), and load tolerances prior to mould opening and profile fabrication.
Skylight leakage is mitigated through a dual-defense system: structural primary weatherproofing and secondary internal gutter drainage. We utilize structural silicone sealant applied in clean-room conditions alongside continuous anti-aging EPDM weather gaskets. Internal mullion channels capture and drain any trace vapor condensation safely to the exterior.
For seaside hotels or desert applications exposed to high UV radiation and salty air, we recommend PVDF (Fluorocarbon) coating (2-coat or 3-coat system conforming to AAMA 2605 specifications). PVDF coatings provide outstanding color retention, chalk resistance, and corrosion protection guaranteed for up to 20 years.
Export safety is paramount. Skylight glass units and assembled frames are wrapped in protective polyethylene scratch films, padded with corner protectors, and packed inside fully enclosed fumigation-free plywood crates. Components are organized systematically according to site installation sequences to simplify unloading on job sites.
