Ordering a rolling door is about more than a price. If the size, headroom, or mounting is wrong, the door will not fit or will fail prematurely. This guide explains the dimensions you need to specify for warehouse, factory, and retail rolling doors.
Key measurements
- Width: Measure the clear opening width plus overlap for the guides
- Height: Measure the clear opening height plus room for the barrel
- Headroom: The space above the opening needed for the rolled slats
- Side clearance: Space for the guide rails and motor bracket
Typical industrial sizes
| Application | Typical width | Typical height |
|---|---|---|
| Small workshop | 2.5-4 m | 2.5-3.5 m |
| Warehouse | 4-6 m | 4-5 m |
| Loading dock | 3-4 m | 3.5-4.5 m |
| Fire station | 4-6 m | 4.5-5.5 m |
Specification checklist
- Confirm the clear opening and headroom
- Choose the slat profile and material (steel, aluminum, PVC)
- Decide the motor type and number of cycles per day
- Check wind load for coastal or high-rise sites
- Request the mounting and electrical requirements
FAQ
What is the minimum headroom for a rolling door?
It depends on the door height and slat diameter. A taller or thicker door needs more headroom. Confirm the exact barrel diameter with the manufacturer.
Can rolling doors be made fire rated?
Yes. Fire-rated rolling shutters are tested as a complete assembly and should ship with the matching certificate.
Should I measure before or after finishing the floor?
Measure after the floor level and wall finishes are complete, or confirm the exact finished level with the contractor so the door length is correct.
