Doorreme Aluminum Industry Co., Ltd. operates a modern 123,000 m² smart manufacturing plant located in Shishan Town, Foshan—the heart of China's aluminum architectural hardware hub. Engineered to serve high-end commercial projects, multi-family developments, and luxury residential estates, our annual capacity exceeds 500,000 m² of custom aluminum windows, heavy-duty doors, and structural curtain wall systems.
To meet demanding global building codes, including North American CSA/NFRC and European CE standards, our factory integrates fully automated production machinery imported directly from Germany and Italy. Operated by an experienced technical engineering team, every production line emphasizes precision tolerances, structural reliability, and energy-efficient performance.
Our integrated manufacturing workflow covers every step from raw aluminum profile CNC machining to automated warm-edge insulating glass sealing and quality inspection.
Smooth, burr-free profile joints are critical to air tightness and water penetration resistance. We utilize Italian Fomindustrie CNC multi-axis cutting centers to achieve sub-millimeter precision. Combined with digital punching and notch routing, each frame section locks tightly, preserving structural stability under intense wind loads.
All hardware mounting slots, drainage weeping holes, and corner assembly joints are processed on automated CNC milling machines. High-pressure hydraulic corner crimping combined with dual-component corner adhesives ensures exceptional mechanical strength and zero water seepage along joinery lines.
Clear visibility starts with spotless raw glass handling. Our multi-stage automatic glass washing machines remove oil, fingerprints, and micro-dust using purified deionized water and high-pressure air knives, ensuring immaculate surfaces prior to double-glazing assembly.
Doorreme Aluminum Industry Co., Ltd. operates a continuous IGU manufacturing line integrating film edge stripping, automated washing, warm-edge spacer placement, automated Argon gas filling, and reactive hot-melt structural sealant extrusion. This delivers superior thermal insulation and long-term seal durability for Low-E glass units.
In our expansive assembly hall, experienced technicians fit premium hardware options—including German Roto and high-grade SS304 multi-point locking systems. EPDM gasket seals are continuously pressed to guarantee acoustic dampening and weatherproofing before final quality sign-off.
Finished window sashes and curtain wall panels are barcoded and tracked in categorized storage racks. Every unit undergoes multi-layer protective packaging—combining protective film, edge corner protectors, foam padding, and reinforced steel-bound wooden crates—to prevent transport damage during ocean freight.
Quality control at Doorreme Aluminum Industry Co., Ltd. is managed through a comprehensive 8-step verification process to ensure flawless performance overseas.
