Allow for the tail as well as the opening
A cantilever fabrication drawing must include the supported tail as well as the visible opening section. Tail length and carriage positions come from the gate design rather than a fixed rule of thumb. The gate includes a supported tail section that works with the carriage arrangement. Its length is determined by the gate design, not by a universal percentage of the opening. Show the fully open and closed positions, including the tail, guides, receiver and all moving clearances.
A nominal 6 m opening does not mean a 6 m leaf or 6 m of runback will be sufficient. Supply the measured side space and finished levels so that the complete movement envelope can be reviewed.
Confirm the carrying components in our custom gate schedule
| Component | Role |
|---|---|
| Cantilever beam and carriages | Support and guide the moving leaf |
| Upper guides | Control the leaf in its designed movement |
| Receiver and stops | Establish accepted end positions and retention |
| Foundation interface | Transfers the assembly loads to the designed support |
The gate mass, infill, wind exposure and operating arrangement affect the design. A more solid infill is not a like-for-like substitution for an open mesh leaf.
Define the automation boundary
Manual and powered gates require different equipment and acceptance work. For powered installations, a competent specialist must assess the complete system, including hazards, protective measures and commissioning. See HSE's powered gate guidance.
The quotation should identify gate materials and hardware separately from civil works, electrical installation and commissioning. Cantilever construction alone does not establish a vehicle-impact rating.
Custom order specification: cantilever sliding gates
| Order detail | What to define with our team |
|---|---|
| Movement envelope | Show clear opening, complete leaf length, side space and open and closed positions. |
| Carrying assembly | Define beam, carriages, upper guides, stops and the foundation interface. |
| Infill and operation | State mesh or screening, finish and the scope of manual or powered equipment. |
Confirm the complete movement and support drawing before fabrication. Changing infill or leaf dimensions requires review of the design and running components. Any powered system needs its separately defined specialist assessment and commissioning.
Can the cantilever gate be supplied without an operator?
State the required mechanical scope and any future operator interfaces in the enquiry. The quotation must identify what is included; later automation still requires assessment of the complete gate system.
