Telescopic Sliding Doors

Cronax Industrial Telescopic Sliding Doors are engineered for wide openings where space efficiency and smooth operation are essential. Designed with multiple sliding panels that move in a synchronized telescopic motion, these doors require minimal side space compared to traditional sliding doors, making them ideal for warehouses, factories, logistics centers, and aircraft hangars. Constructed from heavy-duty steel or aluminium panels, they offer superior durability, weather resistance, and security.

Telescopic mechanism ensures faster opening and closing cycles, optimizing workflow and allowing efficient handling of high traffic and large equipment movement. Available in manual or motorized versions, Cronax Telescopic Sliding Doors can be customized with insulation, transparent vision panels, or full automation integration. Their space-saving design, robust construction, and easy operation make them a reliable and efficient solution for demanding industrial environments.
