Bi-folding gates require precise mechanical design to ensure they operate smoothly and reliably, often involving more complex installation and maintenance than simpler gate designs.

Underground Electric Gates

Underground electric gates offer an aesthetic solution where the gate operator and mechanism are concealed beneath the ground. This type of installation is most common with swinging gates and is favored for its minimal visual impact, preserving the property’s aesthetic appeal. The mechanism is housed in a robust casing below ground level at each gate pivot point. While underground systems are visually pleasing and unobtrusive, they can be more susceptible to water ingress and debris obstruction, requiring careful installation and regular maintenance.

Barrier Arm Electric Gates

Barrier arm gates are commonly used for vehicular traffic control in commercial and residential settings, such as parking garages, business parks, and community entrances. These gates consist of a pivoted bar or arm that extends across the entrance to control access. The arm of the gate is lifted to allow vehicular access, making it an efficient solution for controlling traffic flow in and out of a specific area. Barrier arm gates are known for their rapid operation, making them ideal for locations that experience high volumes of traffic. Installation of barrier arm gates is generally straightforward, involving the setup of a single pole on one side of the entrance that holds the pivoting arm, which can be integrated with various access control systems such as card readers, ticket dispensers, or biometric systems.

Electric gates are a versatile and valuable addition to any property, enhancing security, convenience, and privacy. Each type offers distinct advantages and considerations, from swinging and sliding to cantilever and bi-folding. Property owners should carefully evaluate their specific needs, such as space availability, speed requirements, and aesthetic preferences when choosing the type of electric gate that best suits their situation. With the correct type and proper installation, electric gates can provide reliable service and increase property value for years.
