Cantilever gates are one of the most reliable solutions for closing even large driveways. Suitable for industrial, commercial, agricultural, and airport settings, they are the perfect solution when there is a need to build a very solid structure without ground clutter.
Unlike traditional cantilever gates, this type of opening does not require a rail on the ground: in the composition of a cantilever gate, in fact, the entire structure remains suspended, supported by a mechanical system consisting of cantilever gates placed laterally relative to the opening, and a guide rail that slides on the gates.
An essential feature that makes cantilever gates the ideal choice in all situations where installing a rail on the ground would be difficult or impractical,such as on uneven, rough terrain or affected by mud, snow or gravel.
In industrial or commercial environments with frequent passage of heavy vehicles, moreover, cantilever gates offer a decisive advantage because they eliminate all contact with the ground, preventing the weight of vehicles or dirt from damaging the rail.
Their “suspended” structure also allows for stable and quiet movement, ensuring consistent performance over time even in adverse weather conditions or areas subject to high humidity.
Added to this is a significant savings in maintenance costs: since there are no rails to clean or repair, maintenance activities are limited to a periodic check of the carriages, guide rails and other mechanical accessories, with regular lubrication of the moving components to ensure maximum efficiency of the sliding system, over time.
For these reasons, cantilever gates are now increasingly popular not only in high-traffic industrial facilities but also in modern residential complexes, where design, reliability, and practicality of use are key requirements.
In this guide we will look in detail at the composition of a cantilever gate, illustrating all the main components and accessories that make it up, and delving into the cantilever gate solutions offered by FAC Srl, a leading Italian company in the design and production of components and accessories for residential and industrial gates.

-
What accessories and components are essential to build it;
-
How to choose the right combination of components for your installation;
-
and finally, the individual accessories and complete kits offered by FAC for cantilever gates.
What is a cantilever gate and how it works
The cantilever gate is a suspended sliding structure with no rail on the ground, supported entirely by aamonor rail fixed under the gate structure, which slides on special sliding carriages installed on a concrete base, lateral to the opening gap.
The principle of operation is as simple as it is ingenious: in this structure the gate moves in suspension, resting on two trolleys attached to the foundation. These carts, thanks to their wheels, slide inside a rail, which serves as a guide and structural support.
Thanks to this configuration:
-
the gate remains completely raised off the ground, eliminating problems associated with obstacles, mud, debris or snow in the opening and passage areas;
-
handling is smooth, quiet and stable, even with large openings or heavy weights.
Difference between sliding and cantilever gate
While a traditional sliding gate moves on an earthen guide rail, requiring perfectly level and clean surfaces, the cantilevergate moves suspended.
This aspect makes it the ideal solution in settings where the ground is uneven or unpaved, such as industrial areas, unpaved parking lots, backyards, agricultural areas, or areas subject to harsh weather and environmental conditions, or where heavy vehicles frequently pass through.
Due to the absence of a rail, the cantilever gate offers cleaner aestheticsandgreater transit convenience for vehicles of all types.
Basic components of a cantilever gate
The composition of a cantilever gate is based on a set of perfectly integrated mechanical components, and designed to make systems of various sizes and weights, which work in synergy to ensure smooth and safe movement.
Let’s look at the main elements in detail.
1. Carts
The trolleys are the core of the cantilever system. They are attached to the concrete base and support the entire weight of the gate, allowing the rail to slide.
FAC offers trolleys of different types and capacities, from models for light gates (300-800 kg) to systems capable of supporting up to 4000 kg.
Newer models also include 8-wheel versions, developed to ensure maximum stability and precision in all heavy-duty applications.
All trolleys offered by FAC are made in Italy from high-strength materials, with galvanized or stainless steel wheels and sealed bearings that reduce friction and improve smoothness.
2. Monorail or slide rail
The rail, also called the guideway, is the structural element that slides thanks to the bogies. Available in galvanized or stainless steel, as required, it provides a stable and strong support for the cantilever gate sliding system, allowing it to move without direct contact with the ground.
FAC’s rails (rails) are available in different sizes and thicknesses to accommodate gates with different capacities and openings.
From the most compact solutions, such as the 50×50 mm rails with 3 mm thickness, perfect for cantilever gates with openings up to 4 meters and weights up to 300 kg, to the sturdiest versions, designed for large industrial or logistics entrances where safety and strength are essential.
All FAC cantilever gate rails are also available in standard lengths of 3 or 6 meters to allow maximum flexibility during installation and to easily adapt to different design configurations.
The choice of the rail should always be made in conjunction with the slide carriages, as these two components form the core of the cantilever system and work in close synergy.
In fact, the correct combination of rail and carriage is essential to ensure smooth movement, perfect structural balance, and long gate life over time.
Therefore, it is critical to select trolleys based on the actual gate size and specific project, avoiding sizing errors that can compromise overall performance. An oversized system may result in unnecessarily high costs, while an undersized system is likely to generate operational problems, premature wear and tear, or even criticality in overall system safety.
For these reasons, FAC recommends carefully evaluating the actual weight of the gate, the required opening, and the frequency of use in order to choose the combination of trolley and rail best suited to the needs of each installation.
3. End wheel
The end wheel is located on the front side of the rail and is used to support the weight of the structure during the closing phase.
When the gate is fully closed, the wheel in fact makes contact with the gate leaf on the ground, stabilizing the movement and evenly distributing the weight of the structure (practically, putting the gate “at rest”).
4. Faceplate
The faceplate acts as a rail closure element and prevents debris or foreign objects from entering the rail. It is a simple but critical component for preserving the mechanical integrity of the system and reducing the need for maintenance.
5. Other structural and optional accessories
To complete the cantilever gate composition FAC offers other complementary accessories such as top support plates, supports, tie rods, and anchors. Many of our components are also available in stainless steel versions to ensure maximum safety and efficiency in even the most demanding installations.
How to choose the right cantilever gate composition
In the construction of this type of gate, great care must be taken in choosing the most suitable components and accessories, as each cantilever gate is a complex mechanical system that must be precisely calibrated, depending on the total weight of the structure, the length of the opening, and the expected frequency of use.
Improper sizing can jeopardize the entire system: oversizing results in unnecessarily high costs, while undersizing can generate stability problems, premature wear, or even safety hazards.
For this reason, the selection and design phase assumes crucial importance, and must always be supported by careful technical analysis.
Relying on quality components and an experienced partner such as FAC Srl allows you to choose the most suitableaccessories for each specific installation context, avoiding mistakes that could compromise system operation over time.
So here are the main factors to consider before designing or installing a cantilever gate.
1. Weight and dimensions of the gate
Weight is the first key parameter to consider. To meet any installation need FAC offers accessories for gates from 300 kg to 4000 kg, with openings from 2 to 20 meters. Each set of components is tested to ensure structural stability in relation to the static and dynamic forces of each type of opening.
2. Length of the opening
The greater the opening, the greater must be the strength of the guide. FAC provides rails available in standard lengths of 3 or 6 meters to meet openings up to 20 meters.
3. Environmental conditions
Climatic and environmental conditions are a determining factor in selecting the most suitable cantilever gate components.
A system installed in areas subject to moisture, rain, snow, salt spray, or severe temperature fluctuations requires materials that are highly resistant to corrosion and weathering. In these contexts, the use of stainless steel components is strongly recommended, as it ensures durability, stability and less need for maintenance over time.
For standard applications, however, galvanized steel is an optimal solution.
FAC offers a full range of cantilever gate accessories available in galvanized steel, stainless steel, or rough, to precisely meet the specific needs of each installation.
4. Frequency and context of use
Frequency of use and application context also influence the choice of ideal components for a cantilever gate.
In residential settings, where the number of daily openings is generally limited, it is possible to use trolleys and rails with compact dimensions, which are easily integrated into the design and reduce bulk without compromising stability.
In industrial or commercial settings, however, where the gate is subjected to heavy use and high loads, it is essential to opt for trolleys with 8 wheels and reinforced guides. These innovative solutions developed by FAC are designed to provide maximum load bearing capacity, stability and durability of the structure even under heavy use.
5. Compatibility between components
Compatibility between components is another essential aspect in creating an efficient and safe cantilever gate.
In a cantilever gate, all elements-from rails to carriages, from end wheels to faceplates to backing plates and tie rods-must work in perfect synergy, ensuring stable and smooth movement throughout the opening and closing cycle.
All FAC products are designed and tested to be perfectly compatible with each other, avoiding problems of alignment, premature wear, or unwanted vibration.
