A cantilever sliding gate requires more than a clear opening. The site also needs run-back space for the counterbalance tail, suitable foundations, guide posts, roller hardware and a confirmed interface for any automation.
Before asking for a cantilever gate quotation
- Clear opening and available run-back distance
- Gate height, frame section and infill type
- Foundation conditions and support-post locations
- Manual or automation-ready operating requirement
- Safety devices, access control and finish
Measure the clear opening and the full run-back zone
The clear vehicle opening does not equal the total gate length. A cantilever leaf also needs a counterbalance tail and space for guide and support hardware. Provide the site plan, opening direction, available run-back and any obstruction or level change.
State the gate height and the fence system it must align with. The frame, infill, receiving post and adjacent fence termination should be approved on the same drawing.
Coordinate foundations, hardware and operating method
Guide posts, roller carriages and the receiving arrangement depend on the gate geometry and support design. The project engineer must confirm the foundation zone and structural interface; the supplier should identify the frame and hardware loads used in the approved design.
Automation-ready does not automatically mean that a motor, controls or safety devices are included. List the drive interface, access control, limits, stops, emergency release and safety requirements as separate quotation lines.
Protect the gate frame and identify every hardware set
Long gate frames need controlled support during transport so finished surfaces and geometry are not damaged by direct steel contact or loose hardware. Pack rollers, guides, stops, locks and automation brackets as an identified installation kit.
- Record frame geometry and squareness before packing
- Protect projecting brackets and coated corners
- Mark support and receiving posts separately
- Confirm lifting and unloading points with the buyer
How to request a comparable quotation
State the product, dimensions, quantity, finish, supporting components, installation conditions and destination. Where drawings or a bill of quantities are available, attach them to the RFQ so the system interfaces can be reviewed together.
Final selections remain subject to the approved quotation, project drawings and applicable site requirements.
Common buyer questions
How much run-back space is needed?
It must accommodate the clear opening, counterbalance tail, support hardware and safety clearances. The exact requirement comes from the approved gate design.
Is a cantilever gate supplied with a ground track?
The gate is supported by cantilever hardware rather than a track across the clear opening. Support foundations and roller hardware still require project-specific design.
What does automation-ready include?
It should be defined in the quotation. It may cover agreed frame brackets and interfaces, while the motor, controls, access devices and safety equipment remain separate items.
