How to Size a Roller Door for Warehouses, Workshops and Loading Docks
A well-chosen roller door size can pose better access, safety, and routine workflow in a commercial building. A narrow door is about slow vehicles passing, while a low entrance needs to restrict forklifts and high loads. Getting the measurements right allows you to choose a door that fits your building, equipment, and requirements of your business.
If you’re fitting out a warehouse, upgrading a workshop, or planning a loading dock, you will benefit by accurately measuring the opening before purchasing new doors.
Start with the Door Opening
First, measure the size of the opening in width and height. Utilise a precise tape measure and test each size at different points.
Take the measurement by measuring width in three sections – top, middle, and bottom. Now, take the left, mid, and right measurement height. Note down the smallest readings, these determine where the opening stops/ends.
The side clearance and headroom above the opening should also be inspected. Roller doors require sufficient room for their roll assembly, brackets, and guides. It can be influenced by pipes, lights, beams, and electrical fittings in the installation.
Know Your Business, Know Your Door
Expect each industrial site to have their very own list of accessibility demands. How big that should be depends on what goes through the doorway and how frequently the door is in use.
Warehouses
Large industrial openings are widely required in warehouses to accommodate forklift, pallet loads, and delivery vehicles. Get the width of the widest vehicle or load that has to come through. Give some clearance for safe manoeuvring and turning.
Consider future needs, too. A bit wider opening would offer more flexibility if larger deliveries or new handling equipment are expected.
For businesses looking to install new storage facilities, commercial roller doors in Adelaide can be chosen accordingly for vehicle access, available space and daily warehouse operations.
Workshops
You may need access for cars and vans, for machinery, or service vehicles. Verify the height of any roof racks or other equipment fitted to the vehicle. Do not go overboard with the size of the opening, however, have sufficient space so that the figure can fit inside without having to hunch.
In the case of businesses looking for commercial roller doors in Adelaide, consulting with an installer who is experienced in dimensions relative to vehicle length/height, daily use, and accessible wall space would be worthwhile before selecting a size.
Loading Docks
The planning for loading docks has to be meticulous too, as trucks, forklifts, and goods need to flow between the vehicle and the building. Compare the dock opening with the kinds of trucks you receive and how your equipment moves stock around.
Inspect the dock leveller, bumpers, and any overhead structures. Those features can impact the size of the opening you can actually use and how much space is needed for installation.
Account for Headroom and Side Space
The opening for clarity is only one piece of the measurement. You must constantly account for the size of a roller door’s operating hardware.
Before ordering, check:
- Headroom: Space above the opening for the curtain roll and supporting brackets.
- Side room: Space beside the opening for assistance rails and fixings.
- Operative clearance: The motor, controls, and secure access in support events.
- Structural support: Where the loads and the forces acting on an openable door await to be supported.
An installer may be able to verify that the existing framing is adequate support for the chosen system.
