Product Description
Heavy Duty Industrial Folding Door
Vertical Steel Bi-Folding Door — Engineered for Mega-Scale Industrial Facilities
Product Overview
Our heavy duty industrial folding door is an advanced vertical bi-folding and multi-leaf structural system, specially engineered for large-scale warehouses, manufacturing halls, and heavy industrial facilities operating under demanding conditions. Featuring an exceptionally wide and high clearance design, this steel bi-folding door optimizes overall space utilization while delivering superior structural stability.
Constructed from premium high-strength galvanized steel, the primary framework and internal reinforcement profiles ensure maximum structural integrity and outstanding durability—even under the immense weight of mega-sized door installations. The system supports clear opening widths up to 100 meters and heights up to 30 meters, with multiple leaf configurations available.
Width up to 100m Height up to 30m Wind Load 3.0 kN/m² VFD Smart Drive
Key Features & Technical Advantages
🏗️ High-Tensile Structural Design
Primary framework fabricated from high-grade galvanized steel or heavy-duty aluminum alloy. Engineered to resist deformation and sagging under immense door weight, ensuring decades of reliable service.
❄️ Superior Insulation & Weatherproofing
High-density polyurethane foam core with multi-layer structural paneling provides exceptional thermal insulation. Maintains optimal indoor climate control and minimizes energy consumption.
⚙️ Advanced Smart Drive System
Heavy-duty three-phase industrial motor with intelligent VFD supports variable-speed acceleration and deceleration. Seamless integration with push-button stations, remote controls, or radar sensors.
🛡️ Comprehensive Multi-Layer Safety
Full safety suite including infrared photobeam sensors, airbag bottom safety edge, strobe warning lights, and acoustic movement alarms. Instant halt upon obstacle detection.

Frequently Asked Questions
What is the maximum width for an industrial folding door?
Our heavy duty industrial folding door supports clear widths up to 100 meters (100,000 mm) with multiple leaf configurations. Custom larger spans are available upon request with additional engineering reinforcement.
How does the VFD drive system benefit operation?
The variable frequency drive provides smooth soft-start and soft-stop acceleration, reducing mechanical shock on cables, pulleys, and hinges. It also allows field-adjustable speed between 0.15 and 0.4 m/s for safety and throughput optimization.
What safety devices are included?
Our folding door includes infrared photobeam arrays, pneumatic bottom safety edge, visual strobe warning lights, acoustic movement alarms, emergency stop stations, and overload/temperature protection—all exceeding CE and OSHA standards.
Do you provide installation support?
Yes, we offer comprehensive installation supervision, on-site commissioning, and training. Our project management team provides full turnkey support from foundation design through to final handover.
