Industrial Sliding Door
Industrial sliding doors open and close by horizontally sliding door leaves along tracks. They require no vertical space above the door opening, making them a mainstream large‑door solution for large‑scale factories, warehouses, equipment workshops and logistics parks. They are especially suitable for openings with wide dimensions where overhead space is occupied by overhead cranes or pipelines, rendering sectional overhead doors un‑installable.
They fall into two main configurations: single‑leaf sliding and bi‑parting sliding. In terms of load‑bearing structure, they are categorized into top‑hung type (load borne by top tracks) and bottom‑supported type (load borne by floor tracks). They can accommodate extra‑large‑span openings ranging from several meters up to over twenty meters.
Products Description
01.Track & Travelling Mechanism:
‑ Top‑hung type: Full load borne by overhead tracks with no floor track, keeping ground intact for heavy‑duty truck traffic and avoiding track crushing damage. ‑ Bottom‑supported type: Load‑bearing rollers run on floor tracks for easy installation and commissioning, suitable for sites with complex overhead pipelines and equipment. Wear‑resistant cast‑steel rollers are fitted with limit stops and anti‑derailment assemblies to prevent offset, derailment and jamming of heavy‑weight door leaves.
02.Door Leaf
Mainly made of galvanized steel sandwich panels with 50‑70 mm thickness. Core options include PU, rock wool and PIR for thermal insulation, sound insulation and fire resistance. Vertical stiffeners are added inside leaves for high‑wind outdoor areas to improve torsion‑resistance and wind‑load performance. Frames adopt Q235B galvanized steel sections; 304 stainless steel profiles are recommended for coastal high‑salt‑fog environments against corrosion. Some leaves integrate wickets for personnel access without full‑door opening to save energy.
03.Drive & Control System
Equipped with industrial variable‑frequency operators for soft start‑stop to reduce door impact. Control modes: push‑button, remote control, radar induction, ground loop and card access. Compatible with plant central control and fire‑alarm linkage for automatic opening under fire conditions for evacuation. Manual clutch release for emergency operation upon power failure.
04.Safety Protection System
Standard configurations include infrared light curtain, obstacle‑detection rebound, safety edge, audible‑visual alarm and external emergency‑stop button. The door reverses immediately upon detecting persons, vehicles or obstacles during closing to prevent crushing injuries. Heavy‑duty sliding doors require redundant safety features complying with industrial door safety standards.
05.Sealing System
EPDM rubber gaskets and dust‑proof brushes are installed around door leaves to seal splices and gaps against wind, sand and rain and minimize heat exchange. Reinforced air‑tight sealing structures are adopted for constant‑temperature workshops and cold‑storage rooms to lower air‑leakage rate.
