Core Technical Advantages for Global Projects
Engineered to meet stringent overseas building codes across North America, Europe, Australia, and the Middle East.
Maximum Thermal Isolation
Our dual-chamber profile technology breaks heat transfer paths completely, preventing thermal condensation and delivering peak energy savings in all climate zones.
Multi-Point Security System
Heavy-duty perimeter multi-point locking gear locks the door sash at multiple frame positions simultaneously to prevent forced entry and sash distortion under wind pressure.
Weatherproof EPDM Gaskets
Continuous synthetic EPDM rubber sealing strips resist UV degradation, extreme temperature shifts, and rain penetration, maintaining air tight performance for decades.
Bespoke Hardware & Grids
Tailor your fenestration package with custom muntin bar designs, colonial grids, integrated insect screen meshes, and specialized handle ergonomics.
Precision CAD Customization
Vancoor Entrance System Co., Ltd. produces CAD shop drawings, glass wind-load calculations, and custom structural sub-frames for exact site installation.
Rigorous Quality Inspection
100% pre-assembly in factory prior to export. Frame alignment, corner crimping tolerance, lock operation, and seal integrity are fully validated.
Frequently Asked Questions from Project Buyers
What thermal performance values can Vancoor French doors reach?
When equipped with PA66 thermal break profiles and Low-E double or triple glazing filled with argon gas, our aluminum French doors achieve overall U-factors as low as 1.2 to 1.6 W/m²K, satisfying strict energy codes across North America and Europe.
Are these French doors suitable for coastal hurricane zones?
Yes. We offer heavy-wall aluminum profiles reinforced with steel stiffeners and combined with SentryGlas (SGP) laminated impact glass, passing high-velocity hurricane zone (HVHZ) wind-load and debris-impact requirements.
What is your production lead time and minimum order quantity (MOQ)?
Standard lead time is 4 to 5 weeks from shop drawing sign-off. We cater to commercial multi-housing developments as well as custom private villa projects with flexible order volumes.How does Vancoor Entrance System Co., Ltd. protect goods during ocean shipping?
