What are Cantilever Gate Kits & Components?
Cantilever gate components are specialised hardware sets—including support wheel carriages, enclosed tracks, guide rollers, and end stops—that allow a sliding gate to suspend and glide smoothly over an opening without requiring a ground track. F.H.Brundle supplies individual cantilever components and complete ready-to-install kits from leading manufacturers like Comunello, IBFM, and FAC, supporting gate openings from 3m to 20m and gate weights up to 6,500 kg.

How to choose the right Cantilever Gate?
• Check Run-Back Space: Ensure you have enough tail space behind the opening post to fit the counterbalance section (typically 30% to 50% of the clear opening width).
• Calculate Weight & Wind Load: Total the combined weight of the gate frame, counterbalance tail, and infill material, adding a 15%–20% safety margin for solid-clad gates exposed to wind.
• Match Hardware to Size: Choose your kit series based on span and load—Small/Piccolo (up to 4m / 450kg), Medium/Media (up to 8m / 800kg), Large/Grande (up to 14m / 1,500kg), or Extra Large/Magnum (up to 20m+ / 6,500kg).
• Select Track Material: Choose galvanised steel for general outdoor durability, uncoated raw steel if welding before hot-dip galvanising the entire gate, or aluminium for lightweight residential applications.
• Prepare Concrete Footings: Pour a solid pad extending below the frost line (800mm–1000mm deep) that is long enough to support both anchor carriage blocks.
Where can Cantilever Gates be used?
Cantilever gates are used in locations where traditional swinging or ground-tracked sliding gates are impractical, unsafe, or impossible to maintain. Because the leaf is suspended entirely above the ground, they suit high-traffic, harsh-environment, and high-security settings across commercial, industrial, and residential sectors.
• Logistics & Freight Hubs: Prevents track damage from heavy HGV axle loads and eliminates jams caused by site debris or gravel.
• High-Security Infrastructure: Secures massive openings (up to 20m+) at ports, airports, military bases, and data centres with high-speed automated reliability.
• Public & Educational Facilities: Removes trip hazards for pedestrians while providing dependable perimeter control for schools, universities, and office parks.
• Uneven or Unpaved Ground: Hovers cleanly over gravel, dirt, sloped cross-falls, and uneven driveways where laying a level floor track is impossible.
• Extreme Weather Areas: Operates reliably across snowdrifts, ice, mud, and flood-prone entrances without freezing or clogging.
• Modern Residential Estates: Delivers a sleek, floating aesthetic with quiet, low-maintenance daily operation for private driveways.
Why are Cantilever Gates so popular?
Cantilever gates are popular primarily because they eliminate the biggest point of failure in traditional sliding gates: the ground track. By suspending the gate leaf entirely above the roadway, they offer distinct mechanical, operational, and financial advantages:
• Zero Track Maintenance: Without a floor track running across the entrance, there are no rails to clear of gravel, mud, leaves, ice, or snow that would otherwise derail standard rolling gates.
• Heavy Axle-Load Resistance: Because no hardware rests on the road surface, heavy vehicles like HGVs, buses, and forklifts can drive over the entrance repeatedly without bending or crushing ground tracks.
• All-Weather & Off-Road Capability: They operate seamlessly over uneven roads, sloped cross-falls, dirt tracks, gravel driveways, or flood-prone areas where laying a level concrete track is impossible.
• Quiet & Low-Friction Operation: Internal precision-sealed ball bearings inside the C-channel track shield the rollers from dirt, delivering a whisper-quiet, smooth glide with minimal motor wear.
• High-Security Capabilities: Cantilever hardware can easily handle massive clear openings (up to 20+ metres) and heavy weight loads (up to 6,500 kg), making them ideal for high-speed automated security at ports, logistics hubs, and critical infrastructure.
• Sleek Aesthetic Value: For residential and commercial properties, the “floating” appearance provides a modern look while removing trip hazards for pedestrians.
FAQs
A cantilever gate is a type of sliding gate that is suspended above the ground rather than running on a track across the entrance. The gate is supported by wheel carriages running inside a track, allowing it to open without a ground rail.
Yes. F.H.Brundle supplies individual cantilever components as well as complete kits, allowing installers and fabricators to source additional tracks, brackets, rollers and other hardware as required.
A cantilever gate requires additional space behind the opening to accommodate the counterbalance section of the gate. As a general guide, the tail section may require around 30–50% of the clear opening width, although the exact requirement depends on the system selected and gate design.
Cantilever systems eliminate the need for a ground track, helping to prevent problems caused by gravel, mud, snow, ice and other debris. They can also be suitable for uneven or sloping ground and provide smooth, low-maintenance gate operation.
Yes. Cantilever gates can be used with suitable gate automation systems. The automation equipment must be correctly matched to the gate’s size, weight and operating requirements.
Start by determining the required clear opening, total gate weight and available run-back space. You should also consider the gate’s infill material, wind loading, ground conditions and whether the gate will be manually operated or automated. The kit should then be selected according to its rated opening and load capacity.
Cantilever gate frames can be clad with a range of materials, including mesh, WPC composite boards and aluminium gate infill boards. The weight and wind loading of the chosen infill should be taken into account when selecting the appropriate cantilever hardware.
Yes. Cantilever systems are commonly used for commercial and industrial entrances where reliable operation, security and minimal ground-track maintenance are important. They can also be specified for larger openings and heavier gates than many standard residential sliding gate systems.
Guardian cantilever kits are designed for high-security applications and provide a complete set of rolling and guidance components for heavy-duty cantilever gates. They are intended for applications where additional protection against vehicle impact and secure perimeter control are required.
