The wind resistant rolling shutter door forming machine is a specialized cold bending equipment for producing high-strength wind resistant curtain pieces. Its core is used to manufacture rolling shutter door pieces with reinforced ribs, interlocking interlocking, and high rigidity sections, which can resist strong winds and typhoons. It is widely used in industrial plants, logistics warehouses, coastal shops, large garages and other places with high wind and wind pressure requirements. The equipment can roll shape galvanized steel strip, color coated steel strip, and stainless steel strip in one go, with high automation, high finished product strength, and good wind resistance. It is the core equipment for the production of rolling shutter doors in strong wind areas.

 Mainstream version and wind resistance characteristics

125 type wind resistant curtain: 

• width 125mm, single reinforced rib, thickness 0.4-0.6mm, wind resistance level 8-10, suitable for small and medium-sized shops and garages.

175 type wind resistant curtain: 

• width 175mm, double reinforced ribs, thickness 0.6-1.0mm, wind resistance level 12 (typhoon level), suitable for factories, warehouses, and coastal buildings.

Core wind resistant design：

• Strengthening rib structure: increasing the moment of inertia of the cross-section, making it less prone to deformation under stress;
• Interlocking bite: The curtains tightly bite together, preventing wind and dust, and improving overall rigidity;
• High rigidity material: suitable for thick plates and high-strength steel strips, with strong impact resistance.

Core advantages of the product

• Strong wind resistance: The finished curtain has reinforced ribs and high structural rigidity, which can withstand typhoons of level 12 and is suitable for areas with strong winds.
• High forming accuracy: precision machining of rolling rolls, strengthening rib height error of ≤± 0.15mm, tight interlocking, smooth lifting, and strong interchangeability.
• High production efficiency: Automated assembly line, non-stop cutting, daily production capacity of 3000-5000 meters, suitable for mass production.
• Stable and durable: The whole machine has a heavy-duty structure, with core components quenched and treated, a service life of over 10 years, low failure rate, and is suitable for long-term continuous operation.
• Easy to operate: Intelligent PLC system, one click parameter calling, single person operation, beginners can get started in 30 minutes.
• Flexible customization: The width, thickness, rib height, hole position, and length of the curtain can be customized to meet different wind resistance levels and scene requirements.
