Industrial Door Solutions: Sliding vs. Bi-Folding

The Challenge of Large Openings Warehouses, hangars, and factories need massive openings for trucks and machinery. Standard swing doors are often impractical due to the huge sweep arc they require.

Contender 1: Sliding Doors The door leaf slides horizontally along a track (top-hung or bottom-rolling) to the side of the opening.

Pros:

• Simplicity: Fewer moving parts means lower maintenance.

• Robustness: Ideal for very heavy-duty, intensive use.

• Cost: generally more economical than complex folding systems.

Cons:

• Wall Space: Requires "parking space" on the side of the wall equal to the door width. If you have a 4m door, you need 4m of wall next to it.

Contender 2: Bi-Folding Doors Multiple panels hinge together and stack up (concertina style) against the jambs.

Pros:

• Maximized Width: Clears almost the entire opening width.

• Space Saving: Does not require large side-wall parking space. The folded stack is compact.

• Speed: Motorized bi-folding doors can open very quickly (high-speed variants) for rapid logistics flows.

Cons:

• Complexity: More hinges and rollers mean more maintenance points.

• Headroom: Top tracks may require specific headroom clearance.

Verdict

• Choose Sliding if you have ample side wall space and want a simple, rugged solution.

• Choose Bi-Folding if space is tight or you need the full width of the opening clear without side obstructions.

FAQ

Q: Can these doors be fire-rated? A: Yes, FueGuard offers both Sliding and Bi-folding doors with fire ratings up to 120 minutes, equipped with fusible links that automatically close the door in a fire event.

Q: Are they manual or automated? A: Both. Smaller units can be manual. Large industrial units are almost always motorized with push-button or remote control operation.
