Brief description:Our High-Speed Stacking Doors are engineered for large exterior openings where wind pressure and frequent usage are constant challenges. Unlike standard rolling doors, the stacking mechanism utilizes high-strength lifting straps to fold the PVC curtain into a compact stack at the top. This design provides exceptional structural integrity, making it the preferred choice for heavy industry, logistics hubs, and large warehouses.

The Heavy-Duty Solution for Large Openings & High-Wind Environments
Superior Wind Resistance: Equipped with horizontal steel or aluminum reinforcement ribs, these doors can withstand extreme wind loads (Class 3-4). The structural design ensures the curtain remains stable even in stormy conditions.
Rapid & Efficient Operation: With opening speeds up to 1.5 m/s, these doors facilitate seamless logistics flow, reducing vehicle wait times and minimizing exposure to external elements.
Heavy-Duty Lifting System: High-tenacity polyester lifting straps provide a reliable and smooth folding action. This mechanism is specifically designed for oversized portals where a traditional roll-up system would be impractical.
Exceptional Durability: The curtain is made from high-density, tear-resistant PVC (typically 0.8mm - 1.5mm thickness) with UV protection, ensuring a long service life in harsh industrial environments.
Advanced Safety Protection: Every door is equipped with infrared safety sensors and a flexible bottom edge to detect obstacles instantly, ensuring the highest level of protection for personnel and equipment.
Opening Speed: 0.6 – 1.5 m/s (Adjustable)
Curtain Material: High-density PVC fabric (Flame retardant)
Frame Structure: 1.5mm - 2.0mm Galvanized Steel or Stainless Steel
Wind Load Resistance: Up to 50–100 kg/m²
Operating Temperature: -30°C to +70°C
