6000x7000mm Spiral High Speed Door with Rigid Panel Structure and Anti-Sway Design for Tall Industrial Openings

This Spiral High Speed Door is configured for tall industrial openings around 6000 mm wide by 7000 mm high, where the real challenge is not speed but structural stability at height. A rigid aluminum foam-filled panel leaf runs in a shaftless spiral guide rail, so the panel stack is supported along its full travel instead of hanging from a drum. The rail is anchored to the structural frame at close intervals, keeping the lifting path straight and preventing the panel sway that appears on tall, lightly built doors.
The result is a large opening that still behaves like a production asset: straight panel travel, seals that stay in contact over the full height, and no rattling or panel misalignment after thousands of cycles.

• Panel sway — a tall leaf with insufficient rail anchoring oscillates during lifting, which loads the hinges and the drive.
• Rail deflection — long unsupported guide sections bow under wind and impact, opening the seal gap.
• Seal separation — once the leaf is out of plane, brush seals lose contact over the upper section and draughts appear.
• Hinge fatigue — oscillation concentrates stress at the panel joints and shortens panel life.
• Drive overload — a wandering leaf demands correction torque, so the motor runs hotter than necessary.

• Anchored guide rails — brackets at short intervals fix the rail line to the structural frame instead of relying on the wall face alone.
• Reinforced rail profile — extruded aluminum rail with increased wall section holds straightness over 7 m of travel.
• 43 mm panel — thicker panel with internal ribs controls deflection across the 6000 mm span.
• Shaftless spiral stack — panels park in the spiral housing, so no counterweight or spring system has to hold a tall leaf in balance.
• Servo soft stop — ramped deceleration removes the end-stop shock that loosens anchored rails over time.

• Straight panel path — no sway means no scuffed panel edges and no hinge overload.
• Consistent sealing — the leaf stays in plane, so brush seals work over the full 7 m height.
• Predictable maintenance — rail anchoring and panel joints are checked on a planned schedule rather than repaired after failures.
• High wind tolerance — Beaufort 8 standard, Beaufort 10 with reinforced rails for exposed sites.
• Inspection friendly — the panes are visible from ground level, and a misaligned module can be corrected without dismantling the leaf.

• Tall factory hall entrances and high-bay warehouse gateways
• Aircraft and large equipment maintenance hangars
• Logistics centers with high-clearance vehicle access
• Steel, timber and panel production halls
• Tall external gateways exposed to wind
