    Wondering if a cantilever slide gate is the right choice for your project, application, or environment? The cantilever gate design is counter-balanced to allow the gate to smoothly slide open or closed in a linear motion, closing an opening beyond its vertical support. It’s the perfect solution in environments where a large opening is necessary. Industrial grade cantilever slide gate systems are ideal for locations ranging from airports, military bases, railroads, public service buildings, chemical plants, border stations and more.


    Safer operation

    less chance of the gate interfering or making contact with entering and exiting vehicular traffic.

    Lower overall costs

    an automated gate design that is more efficient, secure and, most often, the lower cost alternative.

    Reduced maintenance

    the cantilever slide gate requires less maintenance to keep its path clear of debris and snow during harsh weather conditions.

    Time tested for over 35 years, our Cantilever Slide Gates are designed to close openings up to 120 feet wide.

    Fortress Heavy Duty Cantilever Slide Gate

    Double Clear Openings up to 60'

    Our Heavy Duty cantilevered gate system is designed to provide unsurpassed rigidity and stability in a variety of operating conditions for single clear openings to 30’ (bi-parting openings to 60′). Four-wheel ball-bearing truck assemblies have been thoroughly tested and designed for use in extreme load and weather conditions.

    White structural cantilever gate

    Fortress Structural Cantilevered Gate

    Double Clear Openings up to 80'

    TYMETAL’s Structural cantilever gate design features a double-track system that can span single clear openings to 40’ (bi-parting openings to 80′). Dual semi-enclosed extruded aluminum alloy tracks provide reliable operation and optimal security in heavy use situations.

    Fortress Box Frame Cantilevered Gate

    Double Clear Openings up to 120'

    TYMETAL Box Frame cantilever slide gates are engineered to close single clear opening widths up to 60’ (bi-parting openings to 120). The box design structure is most effective at resisting wind and gravity. Our box frame design provides exceptional structural integrity and is most  suitable for those larger, more demanding applications.

    Frequently Asked Questions About Cantilever Slide Gates

    TYMETAL has been designing, manufacturing and installing cantilever sliding gates for over 30 years. In that time we’ve also been asked hundreds of questions about our industry-leading gates. We’ve provided some of the most commonly asked questions below. If your question isn’t covered on this page feel free to call our experts or fill out our contact form so we can answer your question!

    There are several forms of slide gates, to include cantilever, overhead and versions that include a ground track and wheels. The main difference is that Cantilever slide gates are not supported by an overhead track or a ground wheel/track system. Cantilever slide gates are supported by either two or four support posts placed to one side of the gate opening. The cantilever gate panel includes one or two tracks, interlocked and welded to the upper horizontal gate frame member. Truck/trolley assemblies are connected to the support posts and the gate panel with track are slid over the truck assemblies.  The gate panel can now easily slide open or closed.  Cantilever gates also include a counterbalance portion, which is 50% of the clear opening width. While increasing the length and weight of the gate panel, the counterbalance portion allows the gate to span greater distances. TYMETAL’s use of custom aluminum extrusions and welding techniques enable our cantilever slide gates to span single clear openings up to 60′.

    Other forms of slide gates require ground wheels and a ground track or an overhead track. Overhead I beams  and ground tracks are costly, particularly that associated with the excavation and installation of a ground track.  Grade variations are harder to address, making it more difficult to accommodate normal drainage requirements. .

    While cantilever slide gates require more space on one side of the gate opening than other gate styles, if space is available it is often the most efficient and cost effective way to span a vehicular gate opening.

    All TYMETAL cantilever slide gates can be motorized.  Based on size, weight and performance requirements we can match any cantilever gate with an automatic slide gate operator that will deliver reliable performance with low maintenance. We also offer a number of access control systems and related design and layout support.



    When choosing your cantilever gate, consider factors such as:

    • Elevation: A cantilever slide gate must be installed level. It’s recommended that the bottom of the gate panel be 5″ above grade, although it can be more or less. If less than 5″ clearance is needed it’s advisable to check with the manufacturer.
    • Storage: The space you reserve for your cantilever gate should include room for the counterbalance or the additional length of the gate that goes past the opening length.  The overall length of the gate panel is 1-1/2 times the clear opening width, which is the storage requirement when the gate is in the open position.
    • Infill type: Typical infills include steel 2″ x 2″ x 9 gauge chain link, ornamental pickets, anti-climb panels, expanded metals and other. When selecting infill it is important to consider weight and density.
    • Single track, double-track or box frame configuration: The Heavy Duty (single track) Cantilever Slide Gate can span clear opening widths up to 30′. Structural (double-track) Cantilever Slide Gates can span clear opening widths up to 40′.  Box Frame Cantilever Slide Gates can span clear opening widths up to 60′.
    • Opening width: Your cantilever gate’s opening width will determine the style of cantilever slide gate that is most suitable.
    • Gate height: While not as important as your gate’s opening width, your cantilever gate’s height will also influence your gate’s overall structure. Height affects the gate’s wind load, determining what infill materials, hardware and supports you need to use.
    • Gate weight: Most aluminum cantilever gate weights do not exceed 2,000 pounds. When selecting an infill component it is important to consider weight and density. Typical 2″ x 2″ x 9 gauge chain link and most aluminum picket configurations are well within weight and density limitations. When selecting heavier or denser components it’s best to check with the manufacturer first.

    TYMETAL also offers a variety of options in ornamental cantilever gates that provide optimal security along with an attractive design and finish. Frames and pickets are fabricated from aluminum alloy extrusions with Internal, External, Flat-Top or Smashed Point styles available. Ornamental cantilever slide gates also come in convex or concave configurations, with a choice of milled aluminum or baked-on powder coating in standard or custom colors. These additional options help bring your aesthetic vision to life.

    Steel is corrosive and aluminum is not. Even galvanized steel can rust in some areas. Aluminum, however, is protected by a thin layer of its natural corrosion properties, aluminum oxide. The aluminum oxide is a natural, rust-resistant shield. Most important, while providing strength, aluminum is lighter than steel.  Steel is just too heavy a material for cantilever style sliding gates. The excessive weight is hard to move, stresses cause weld breaks at joints and gate operators strain to power them. TYMETAL’s cantilever slide gate systems are well engineered and manufactured in a controlled environment.  They benefit from an enclosed track and truck/trolley system that is protected from debris and weather.  The combination of custom extrusions, hardware and manufacturing technique insure superior performance over time – and a solid long term investment.
