International Credentials & Patented Engineering
Guangdong Dejiyoupin Doors and Windows Co., Ltd. operates under strict international production benchmarks. Every system engineered for Australia, New Zealand, and global trade undergoes rigorous physical testing to ensure structural endurance, airtight seals, and cyclone resilience.
With more than 100 national invention and utility patents, our product architecture guarantees precision execution from extrusion to glazing. Our patented Four-Side Six-Point anti-theft locking hardware and proprietary acoustic profiles deliver certified performance you can specify with complete confidence.
Certified for structural deflection, operating force, air infiltration, and water penetration compliance.
Tested against cyclic wind pressure and high-velocity debris impact for high-wind coastal zones.
Harmonised thermal, structural, and safety verification across Europe, the USA, and Canada.
Comprehensive 360° factory quality assurance systems spanning every manufacturing stage.
Engineered to Exceed Oceania Building Codes
Comprehensive laboratory validation designed to satisfy local certifiers, council approvals, and structural engineers.
AS 2047 & AS 4055 Compliance
Engineered for Australian wind load standards. Our windows and doors undergo full-scale laboratory testing for deflection under ultimate limit state (ULS) and serviceability limit state (SLS) conditions.
- Air infiltration & exfiltration ratings
- Water penetration resistance up to specified Pa
- Operating force verification on sash hardware
AS 1288 Safety Glazing
Glazing units adhere strictly to human-impact requirements and structural span limitations. We supply Grade A safety glass including toughened, laminated, and Low-E double glazed combinations.
- Impact-resistant laminated security options
- Argon-filled hermetically sealed IGUs
- Warm-edge thermal spacing technology
NCC 2022 & NZBC H1 Energy Targets
Engineered thermal break profiles coupled with high-performance Low-E coatings deliver superior U-values and solar heat gain coefficients (SHGC) tailored for residential and commercial energy audits.
- Polyamide thermal breaks to prevent bridging
- Complete condensation control drainage paths
- Validated thermal simulation documentation
