Premium Horizontal Sliding Doors

Horizontal Sliding Door Systems

Not sure what configuration of horizontal sliding door is best for your facility? Mega Door Co. has NO geographical limitations. Whether you are building a brand-new private aircraft hangar, expanding a commercial aviation facility, or retrofitting a large industrial warehouse, our certified technicians travel directly to your job site.

Why Choose Mega Door Co. Horizontal Sliding Doors?

Horizontal sliding doors are easy to install, look great, and offer a great deal of weather protection from the elements. What’s more, horizontal sliding doors move independently of each other so no matter how large your hangar is, horizontal sliding doors can be installed to enclose the space. They attach to the hangar on the top and use rails on the bottom to secure them to the ground. 

At Mega Door Co., we engineer our horizontal sliding systems to deliver maximum structural integrity and reliable day-to-day performance. By combining precision overhead guide systems with ground-supported rail technology, these doors distribute structural weight safely to the foundation slab. This design eliminates the excessive truss-loading associated with overhead doors, allowing you to maximize opening width without compromising your building's structural footprint.

Key Configurations & Engineering Features

Independent Multi-Leaf Stacking

Because each door leaf operates independently on its own dedicated rail channel, you can configure your opening exactly as needed. Open a single leaf for personnel or small support vehicles, open several leaves for light aircraft, or slide all leaves back to clear the entire building span. This independent movement reduces unnecessary cycle wear and cuts down on thermal loss by keeping unused sections closed.

Heavy-Duty Bottom Rail Guidance & Load Distribution

Horizontal sliding doors carry their load either directly on bottom rollers or via an overhead top-hung track:

• Bottom-Rolling Systems: Transfer the door's full weight directly to the foundation floor slab, eliminating heavy dead-load requirements on the building’s roof headers and trusses.
• Top Guide Rollers: Keep the door aligned, stable in high crosswinds, and gliding smoothly along upper channels without rattling, binding, or jamming.

Maximum Vertical Clearance & Zero Lost Headroom

Unlike vertical lifting, bi-folding, or hydraulic swing doors that require clearance arcs or eat into your door header height, horizontal sliding doors slide cleanly out of the way into side pockets or adjacent wall overlaps. You retain 100% of your vertical clear opening height from edge to edge.

Superior Weather Sealing & Wind Resistance

Built to withstand severe gusts, driving rain, heavy snow, and harsh coastal environments, Mega Door Co. horizontal sliding doors feature:

• Heavy-duty EPDM dual-lip rubber weather seals along all vertical, top, and bottom edges
• Interlocking panel joggle seals that eliminate drafts, moisture infiltration, and dirt entry
• Wind-load engineering certified to meet stringent airport, commercial, and coastal building codes

Horizontal Sliding Door System Options

Bi-Parting Horizontal Sliding Doors

Designed for mid-to-large openings with adequate clearance on both sides of the entryway. The panels divide down the middle and slide outward in opposite directions, cutting opening and closing cycles in half while balancing the visual symmetry of the structure.

Unidirectional Single-Slide Doors

Engineered for facilities with exterior or interior stacking clearance on only one side of the structure. All leaves travel in a single direction and nest cleanly against one designated side wall, maximizing site utility when property lines or adjacent buildings prevent two-sided clearance.

Floating & Multi-Track Sliding Systems

Ideal for wide multi-bay corporate hangars and industrial facilities. Each door leaf floats freely across a multi-rail track system, allowing operators to create customizable openings anywhere along the span to access specific equipment or aircraft without moving the rest of the doors.

Telescopic Sliding Doors

The ultimate space-saving solution for buildings with limited side-stacking space. Using linked multi-track hardware, the door leaves cascade alongside one another into a compact, nested footprint, delivering a wide clear opening even on tight footprints.
