    Gates are the finishing touch on any fencing system. Often it is the most critical and complicated aspect of the project. From simple pedestrian entrance gates with pad-lockable latches to rugged, large-vehicle gates designed for 90 mile per hour wind loading, A-1 Fence can provide them all. Your sales specialist can discuss all your options and will work with you to recognize the most cost-effective entry solution to fit your site requirements. All are available in chain link or ornamental metal.

    Swing Gates

    Swing gates provide the easiest pedestrian access, and double swing gates can span larger openings for trucks, forklifts, and multi-lane vehicle requirements. Gates that swing over sloped entrances require special consideration.

    Roll Gates (single and double)

    Roll gates with rubber wheels are simple, low cost solutions for wider access openings and are generally more secure than swing gates. The gate “parking” areas must be large enough to accommodate the full width of the gate opening plus an additional over-lapping distance (usually 2’ - 4’) to include the gate extension and safety hardware.

    Roll gates with Ground Track

    Roll gates with ground track (commonly called sliding gates) and “grooved wheels” provide better coverage for larger openings, more secure entries and ground conditions that would otherwise misdirect any unguided gate travel.

    Cantilever Roll Gates

    Cantilever roll gates require no ground track and can cover unfinished driveways, snow, gravel and other unusual terrain conditions. These gates require gate extensions that are generally an additional 50% of the gate opening. For example a 10’ wide gate opening requires a 15’ long gate.

    Barrier Arm Gates

    Barrier arm gates (horizontal swing arm gates) can easily span parking entrances areas and are more subtle solutions where pedestrian security is not required.

    Crash-deterrent Options

    Heavy-duty designs, anti-ram and crash deterrent options are also available. Ask your architect or have our sales representative make recommendations that can answer the most unique conditions.

    Gate Safety

    All existing gates should be periodically inspected, including the hardware. Vehicle damage, landscape growth, corrosion or vandalism can render the gate insecure and can also create dangerous conditions for pedestrians and vehicles. For roll gates, reinforced, positive stops should be in place for both directions of travel. Gates should have permanent safety posts or “gate hooks” to prevent the gate from falling over if the rolling or guide hardware are damaged or removed.

    Additional safety information on sliding gates can be referenced in the California Labor Code, Section 142.3. Recent regulations were filed with the Secretary of State under General Industry Safety Orders/Horizontal Sliding Gates.

    Roll gates on slopes, grades or across flow-lines must be properly designed to function with a reasonable amount of effort. Excessive slopes may allow a moving gate to “run-away” from its operator, causing damage to the gate or personnel. Alternate configurations should be considered.

    Automated gates have their own special safety requirements. See below.

    Gate Hardware

    Locking hardware options are too numerous to discuss here in detail, so make sure you and our sales specialist discuss the options. Padlocks, dead bolt and dead latches are most popular but a full range of security locks and electronic controls will allow you to integrate any gate into your complete perimeter security package. Even your existing alarm/access system can be interfaced with your gates.

    Pedestrian Gates in the 'path-of-travel' are usually required to comply with ADA standards.

    Gate Closers

    In general, small pedestrian gates can be closed using a simple closing device, like a spring, spring-loaded hinge, a hydraulic closer or other standard device. These devices are easy to adjust and also easy to get out-of-adjustment, so you should not exclusively rely on these where true re-latch security or safety are required. Hydraulic closers should be mounted on an overhead transom and therefore work best on gates 7’ high or greater.

    Check with your hardware specifier if a heavy pedestrian gate has been designed.  Most hydraulic closers will not be able to control these heavy designs.

    One note of caution - if you or your architect designs a gate for us to build, make sure you specify a closer that will work.   The "5 pound pull" test can not be achieved on heavy pedestrian gates.

    Gate Hinges and Latches

    A properly installed gate should operate smoothly, with minimal effort. Consider how many times per day the gate will be opened and also the individuals that will be expected to open them. Good quality hinges are a worthwhile investment. Large swing gates require large hinge posts with big footings to maintain a stable swing platform. Roll gates have a variety of gate roller options that reduce the amount of effort required to move them.

    Your gate receiver can be as simple as a section of chain welded to your latch post, a standard gate latch or a complete locking mechanism. Panic bars are a common option in commercial yards and other secured areas where employees must be allowed to freely exit during emergencies.

    Gate Automation

    See our section on Access Controls and Gate Automation »

    Gate Fabrication

    Most commercial and industrial gates are shop fabricated, whether they are made of chain link or ornamental metal. This is done to reduce your installation time and to build a gate that fits your required dimensions. Shop fabricated gates have limited warranties. When there is sufficient lead-time, a pre-manufactured gate can be ordered. The benefit is that the gate can be properly finished to provide the best corrosion protection and service life. However, in addition to extended lead times, the cost of shipping large gates very quickly becomes prohibitive. Your sales specialist will cover these options as well.

    Gate Finishes

    Just like the coating on your fence, your gate can come with a variety of corrosion protection options. Fragile, expensive gate finishes are subject to shipping damage and even the greatest installation crews must use tools and lifting equipment to install larger, heavier gates. See the Resources section FAQ's on coatings and finishes, specifications, corrosion protection and extended warranties are discussed.
