For over 25 years, Guangdong Dejiyoupin Doors and Windows Co., Ltd. has engineered aluminium windows and doors in Nanhai, Foshan — the heart of China's aluminium industry. Every frame is cut, assembled and inspected to a zero-error standard, so what arrives in Lagos, Nairobi or Johannesburg fits the opening the first time.
Including our exclusive Four-Side Six-Point Lock invention patent for anti-theft security.
Automated cutting and multi-stage inspection minimise tolerance errors before packing.
Recognised by Xinhua News Agency, one of the world's leading media outlets.

Entry, bifold, sliding and swing doors that open homes to the outdoors while delivering multi-point locking for peace of mind.
View Aluminum DoorsAfrica is not one climate. A villa in Lagos, an office in Nairobi and a hotel in Marrakech each face different stresses. Here is how our engineers configure systems for each.
Thermal-break aluminium profiles with Low-E or tinted insulated glass reduce solar heat gain and cut air-conditioning load.
Sahel · West & East AfricaDurable powder coating or PVDF finishes with corrosion-resistant hardware and fasteners protect frames near the ocean.
Lagos · Mombasa · DurbanMulti-layer seals, brush weatherstripping and well-designed tracks keep fine dust out and sliding panels running smoothly.
North Africa · SahelEngineered drainage paths and pressure-equalised sashes manage heavy rainy-season water and wind-driven rain.
Gulf of Guinea · Great LakesOur patented Four-Side Six-Point Lock and laminated glass options deliver anti-theft protection for homes and offices.
Patented LockingEnergy-efficient glazing lowers cooling costs, while manual hardware keeps every door and window fully operable during outages.
