Custom Architectural Folding Door Systems Manufactured in China
Veltor Window & Door Co., Ltd. is a premier manufacturer specializing in heavy-duty, thermal break aluminum bi-fold door systems engineered specifically for commercial developments, hospitality projects, and luxury residential applications worldwide. Operating out of our state-of-the-art production center in Foshan, China, we convert high-grade architectural aluminum profiles into custom, high-performance folding glass wall systems.
Our bi-fold doors are designed to eliminate the boundary between indoor and outdoor spaces while delivering superior structural stability, air tightness, and energy efficiency. By utilizing multi-chambered thermal break technology, polyamide insulation strips, and precision German hardware options, our systems meet or exceed international building codes across North America, Australia, Europe, and coastal hurricane zones.
High-Density PA66 Thermal Insulation
Features German-engineered PA66 polyamide insulating strips that effectively decouple exterior heat or frost, reducing U-factors and enhancing structural rigidity.
Heavy-Duty Bottom Carriage & Top Guides
Smooth stainless steel rollers and double-track guide hardware support leaf loads up to 120kg per panel, ensuring effortless, whisper-quiet gliding operation over tens of thousands of cycles.
Continuous Weatherproofing Seals
Triplicate EPDM gaskets with vulcanized corner connectors prevent water penetration and air infiltration even during high-pressure storm environments.
Flexible Configurations & Sills
Supports 2 to 7+ leaf stacking options with inward or outward opening directions, as well as low-profile weather-tight sills and flush floor thresholds.

Why Overseas Project Buyers Partner with VELTOR
Procuring fenestration products internationally requires reliable quality assurance, clear communication, and export-compliant logistics. Veltor Window & Door Co., Ltd. provides a streamlined end-to-end service designed for project contractors, importers, and regional distributors:
1. Precision CAD Shop Drawings
Prior to extrusion cutting, our engineering department converts structural architectural plans into millimeter-accurate shop drawings, specifying opening directions, drainage paths, jamb details, and glass unit builds.
2. Uncompromising Quality Inspection (QC)
Our quality control engineers perform 100% pre-shipment assembly tests in our Foshan factory. Each bi-fold unit is tested for smooth rolling motion, gasket compression, diagonal squareness, and hardware engagement.
3. Overseas Export Packaging & Labeling
To ensure safe ocean freight, frames are wrapped in protective anti-scratch film, corner-guarded, and packaged alongside glass units into steel-reinforced wooden crates. Every panel and frame is labeled by opening tag number for rapid on-site assembly.
Frequently Asked Questions for Project Procurement
What is the lead time for custom bi-fold door container orders?
Standard manufacturing lead time ranges between 25 to 35 business days following formal approval of shop drawings and deposit confirmation. Specialized PVDF or custom RAL powder colors may extend timeline slightly.
Can Veltor Window & Door Co., Ltd. supply hurricane-impact rated bi-fold doors?
Yes, we provide engineered bi-fold door variants reinforced with continuous heavy-duty mullions and SentryGlas (SGP) laminated safety glass designed to pass wind pressure and impact testing requirements for coastal regions.
How do you facilitate installation support for international dealers?
We supply comprehensive installation manuals, video walkthroughs, step-by-step section drawings, and direct remote technical support with our engineering team for field crews.
