8000x5000mm Wide Opening Spiral High Speed Door with Multi Rail Wind Lock and Rigid Panel Structure for High Speed Spiral Door Systems

This Spiral High Speed Door is engineered for wide industrial openings of approximately 8000 mm wide by 5000 mm high, where structural stability is governed by span rather than height. A rigid aluminum foam-filled panel leaf is guided by a multi-rail arrangement: the standard side rails plus an intermediate wind lock that keeps the wide panel stack from bowing between the frames. Panels are 220 mm modules at 43 mm thickness, so the leaf behaves as a stiff plate across the full width.

Wide openings are where low-cost doors deform first. This model is specified so that the leaf stays flat, the seals stay closed, and the panel joints stay tight even under crosswind and repeated forklift traffic.

• Multi-rail layout — additional vertical support reduces the unsupported panel span and keeps the leaf in plane.
• Wind locks — intermediate locking points resist crosswind pressure on a 40 m² leaf.
• 43 mm panels — thicker foam-filled modules raise bending stiffness without adding a separate frame.
• Reinforced hinges — hinge line sized for the panel weight carried across the wide span.
• Heavy rail anchoring — bracket spacing tightened at the rail ends, where load concentrates.

• Flat leaf, closed seals — wide panels stay true, so brush seals do not lift at the edges.
• Wind stability — Beaufort 8 standard, Beaufort 10 with the reinforced rail and wind lock package.
• Clear full-width opening — panels stack in the spiral housing, so no centre post reduces usable width.
• Fast traffic flow — 1.0–1.5 m/s opening speed suits wide-vehicle access without holding the opening open.
• Serviceable modules — a damaged 220 mm module is replaced on site.

• Wide warehouse and distribution gateways
• Cross-dock corridors with side-by-side vehicle access
• Large equipment and steel fabrication halls
• Vehicle service and wash bays
• Exposed gateways with crosswind load
