Frequently Asked Questions
What makes Vancoor Aluminum Bi-Fold Doors an energy-efficient choice for global projects?
Vancoor Entrance System Co., Ltd. manufactures folding doors using high-grade 6063-T5 extruded aluminum profiles equipped with integrated PA66 polyamide thermal break strips. When combined with Low-E double or triple tempered glazing and argon gas fill, heat conduction is drastically reduced, helping your project satisfy strict regional energy compliance standards (such as NFRC, Title 24, and CE standards).
What are the maximum dimensions and panel configurations available for bi-fold doors?
We specialize in heavy-duty, large-span custom configurations. Individual sashes can reach up to 3000mm in height and 1000mm in width. By combining multiple panels (e.g. 3+1, 5+0, 6+6, or up to 10+ sashes), openings exceeding 12 meters wide can be seamlessly filled with light, effortless sliding movement.
How do your aluminum bi-fold doors perform under heavy wind and storm conditions?
Our bi-fold sashes utilize reinforced multi-chamber aluminum structural extrusions, heavy-duty stainless steel top/bottom tracks, and triple-sealed EPDM gaskets. This combination delivers exceptional resistance to air infiltration, heavy rain penetration, and hurricane-force wind pressure.
What surface finishes and RAL color options do you provide for custom architectural doors?
We offer architectural-grade powder coatings (AkzoNobel / PPG), anodized finishes, fluorocarbon (PVDF) coatings for coastal high-salinity zones, and realistic wood-grain thermal transfer prints. Full custom RAL color matching is available for all project orders.
What quality assurance and export packaging standards are used for international sea transport?
Every order undergoes rigorous factory testing and pre-assembly verification. All components are wrapped in protective PE anti-scratch film, fitted with corner protection guards, wrapped in bubble cushioning, and packed securely inside sealed export plywood crates to guarantee damage-free arrival at destination ports.
