Sliding Doors
Bottom Mounted Sliding Door
Floor-tracked industrial sliding door delivering superior lateral stability for heavy panels and wind-exposed openings.
Bottom-mounted sliding doors run on a floor track with upper guide rail—providing improved lateral stability for heavy steel panels and wind-exposed openings where a top-hung system's cantilever deflection would be unacceptable. The practical choice for heavy-gauge agricultural, industrial, and cold store applications where panel weight and wind load exceed the limits of a track-free system.
Engineering notes
Floor track provides lower guidance and lateral stability—suited for heavy-gauge steel panels and wind-exposed openings where a top-hung system's cantilever length creates unacceptable deflection.
Upper guide rail prevents panel rocking and lateral oscillation without carrying structural panel load—a complementary restraint that adds stability without transferring weight to the wall.
Threshold coordination and drainage detailing prevent debris accumulation and water ingress at the floor track position.
Typical applications
- Agricultural barns and farm buildings
- Industrial and factory buildings
- Cold stores
- Warehouses
- Wind-exposed coastal and rural sites
