At Guangdong Dejiyoupin Doors and Windows Co., Ltd., every aluminum architectural system is backed by certified testing. From thermal transmittance (U-value) to structural wind resistance and water tightness, our windows and doors comply with rigorous European and international performance codes.
Certified for complete compliance with European Construction Products Regulation (CPR). Validated by accredited notified bodies for residential, multi-family, and commercial building envelopes across the EU.
Our entire 180,000 m² manufacturing plant operates strictly under the ISO 9001 certified quality management framework, ensuring full batch traceability from raw aluminum extrusions to packaged deliveries.
Guangdong Dejiyoupin Doors and Windows Co., Ltd. holds national invention patents for high-security locking mechanisms, engineered to resist forced entry and structural deflection under negative wind pressure.
Thermal break profiles tested in accordance with NFRC procedures, verifying solar heat gain coefficient (SHGC) and U-factor ratings that conform with low-energy architecture and Passive House standards.
Comprehensive accreditation ensuring structural profile strength, safety glazing standards, and extreme weather resilience in severe maritime and coastal environmental conditions.
Engineered with heavy-duty structural aluminum extrusions and structural silicone glazing to resist cyclic wind pressures and high-velocity projectile impacts without frame displacement.
For European contractors, importers, and developers, risk mitigation starts at the factory floor. Guangdong Dejiyoupin Doors and Windows Co., Ltd. issues comprehensive Quality Inspection Dossiers for every export shipping container, including mill test certificates for 6063-T5 aluminum, powder-coating thickness tests (Qualicoat standard), and sealing performance records.
Our export engineering department is fully equipped to provide custom technical declarations, structural calculation books, and thermal simulation reports for your local municipal planning permissions.
