Spiral High Speed Door with 220mm Aluminum Panels and Friction-Free Helical Rail for 7000x8000mm Oversized Openings

The Spiral High Speed Door with a helical guide rail is a rigid-panel rapid door built for oversized openings such as 7000 mm wide by 8000 mm high (approximately 56 m²). Instead of winding the curtain tightly onto a drum, the door lifts each 220 mm wide aluminum panel along a continuous spiral track. Panels stay parallel and separated through the whole travel cycle, so there is no layer-to-layer pressing, no edge rubbing and no abrasive contact between panel faces.

This friction-free path is the core difference from roll-up shutters and soft PVC doors: the panel surface keeps its coating, its flatness and its thermal performance far longer, which directly reduces replacement cost and service downtime on high-traffic factory gateways.

In a traditional roll-up structure the curtain is coiled layer over layer under tension. Every opening cycle presses panel against panel, and every closing cycle drags the surface against the guide. Three problems follow:

• Coating wear — paint and film polish away along the coil radius, exposing the base material to moisture and corrosion.
• Edge fatigue — repeated bending at a small radius creates micro-cracks that grow into panel deformation.
• Seal distortion — a warped panel no longer meets the brush or rubber seal, so wind, dust and heat leak through.

The spiral guide rail removes the root cause: without tight winding there is no pressing force, and without pressing force there is no abrasion.

• Panel pickup — the servo drive lifts the bottom panel, which enters the spiral guide rail at the side frame.
• Helical travel — each panel follows the curved aluminum rail with rolling contact only, keeping a 2–3 mm clearance to the channel wall.
• Parked position — panels stack in the spiral housing above the opening, leaving the traffic lane fully clear and saving headroom compared with sectional doors.
• Controlled deceleration — the servo controller ramps speed down at both end positions, protecting the rail and the panel joints on a 56 m² panel stack.

• Friction-free panel path — rolling contact only, no sliding abrasion between panels.
• Wear-resistant 220 mm panels — 0.7 mm aluminum skin over PU core, 40 mm or 43 mm thick; 43 mm is recommended for the 8 m lifting height.
• Fast cycles — opening speed 0.6–1.2 m/s, tuned for oversized panel weight.
• 220 V single phase operation — standard single-phase supply, no three-phase conversion needed on site.
• Weather and wind stability — Beaufort 8 standard, Beaufort 10 with reinforced rails and wind locks.
• Low maintenance — no springs, no winding drum, no curtain re-tensioning.

• Reinforced double-wall guide rail and additional wind locks for a 56 m² panel stack.
• Extra internal reinforcing ribs at 43 mm panel thickness to hold flatness over 8 m of lifting height.
• 1.5–2.2 kW servo drive sized for total panel weight with a safety factor.
• Balancing system and hand-crank release validated for full-height manual operation after power failure.
• Site drawing issued before production to confirm headroom, spiral housing clearance and fixing points.

• Front-mounted on an existing wall face
• Between-wall installation to save lateral space
• Low headroom layout with reduced spiral housing for restricted ceilings
• 90-degree corner layout for side-running traffic lanes

• Large industrial workshop and production hall entrances
• Warehouse and distribution center transfer zones
• Logistics sorting and dispatch corridors
• Aviation, steel and heavy equipment workshops with tall openings
• Parking and vehicle access gateways
