» 1. Material Preparation and Selection
The process begins with the selection of high-quality materials, such as galvanized steel or aluminum, for the door’s structural components. These materials ensure durability, corrosion resistance, and long-term reliability.
» 2. Precision Cutting and Machining
Using CNC cutting technology, the door panels and structural components are precisely cut to the required dimensions. This ensures that each part meets the strict specifications needed for the smooth operation of the high-speed spiral mechanism. The key structural components, such as the spiral tracks, are machined with an accuracy of up to 10 microns to allow seamless door movement.
» 3. Assembly of the Spiral Track
The spiral track, made from precision-machined aluminum or steel, is assembled. This double spiral design enables the door panels to roll up efficiently without causing wear or requiring frequent maintenance. The automated spline shaft system is integrated into this step, which is designed to be maintenance-free and highly durable.
» 4. Door Panel Production
The individual door panels are manufactured and assembled. These panels are often made from materials like insulated steel or aluminum, providing both thermal insulation and structural integrity. The panels are coated with protective layers to enhance weather resistance and reduce noise.
» 5. Final Assembly and Testing
After assembling the spiral tracks and door panels, the high-speed door system is tested for smoothness and efficiency. The door is operated multiple times at its rated speed to ensure it meets performance standards, including wind load resistance, airtightness, and operational speed.
» 6. Quality Inspection
A final quality control step is performed to ensure all components meet the required standards. This includes checking the thickness of the materials, the integrity of the spiral tracks, and the overall operation of the door system.
Frictionless operation, capable of more than a million cycles.
The thermal break provides insulation and helps save energy.
