This reviews the importance of choosing the right gate system for commercial properties and new construction projects with an introduction to the four major types of gates: a swing gate, a double swing gate, a cantilever gate and roller gate system.  At AMETCO, we design and manufacture these types of gates using infill panels to match your security, weight, durability and cost requirements. Below is a short overview of each style of gate.

Swing Gates
Swing gates pivot from a post and swing outward or inward, resembling a standard door. They're Ideal for properties with ample entry space to accommodate the gate's arc.

Simplicity of design and operation.
Cost-effective in terms of installation and maintenance.
Requires significant space for the swing radius.
Can be challenging in snowy or icy conditions, as accumulation can prevent operation.

Swings are usually operated manually or powered by electric swing gate operators.

Double Swing Gates
Similar to single swing gates, but consists of two gates that meet in the middle. Double swing gates are often installed on wider entrances where a single swing gate would be impractically large and very heavy.

- Allows for a wider entry point.
- Balanced, as the load is distributed between two gates.
- Requires more maintenance, particularly at the hinges and the meeting point.
- More components involved, which can increase potential points of failure.

Typically larger swings gates are installed with automated operators on both gates similar to an automatic garage door opener.

Cantilever Gates
Cantilever Gate Systems are significantly more robust, and are supported on rails that run along the inside of the fence structure and operate in a sliding manner without touching the ground. Cantilever gates are best for areas where the ground is uneven or where minimal contact with the ground is preferred (e.g., industrial areas with heavy dirt or debris).

- No ground contact means less wear and tear and smoother operation in various weather conditions.
- Suitable for wide and heavy gates.
- Requires more lateral space along the fence line.
- More complex installation and higher initial cost.

This type of gate system is most often operated by a motor and a sliding mechanism along the rail. This below fo more detail on the operation and installation of cantilever gates.

Roller or V-Roller Gate System
A v-roller gate system moves along a track installed on the ground, guided by rollers on either side of the gate. Roller gates are ideal for secure, heavy-duty applications, particularly where space beside the gate is limited.

- Effective in providing high-security with robust operation.
- Functions well in limited spaces without extra lateral room.
- Track requires regular maintenance and debris clearance.
- Installation can be complex and costly, especially for larger gates.

Typically v-roller or roller gate systems are powered by a chain-driven motor that moves the gate along the track.

When deciding which gate system to specify or install, factors like space availability, budget, maintenance capabilities, and security needs should be considered.

More on Cantilever Gates and V-Roller Gates
Since they're more complex, we're expanding on the design and installation requirements for cantilever gates and V-roller gates, which are popular in commercial settings due to their durability, security, and specific operational needs. Most projects should be installed by professionals.

Cantilever Gates
Design Requirements
Structure: Cantilever gates are designed without any ground support over the gate opening. Instead, they are supported by rails that run along the inside of the fence. The gate must be constructed with a counterbalance section, typically making the gate 1.5 times the length of the opening. This counterbalance is essential for stability and smooth operation.

Materials: These gates are often made from aluminum or steel, which provides the necessary strength while keeping the structure manageable in weight. The choice between aluminum and steel often depends on the required strength and the environment (e.g., steel is more robust, but aluminum is more resistant to corrosion and lighter weight).  Ametco offers a vareity of both aluminum and steel infill panel designs to match any application.

Rail System: A cantilever gate uses rollers mounted on the fence posts with a horizontal rail that extends from the gate. This rail must be precisely aligned to ensure smooth and stable movement.

Installation Requirements
Foundation: A strong foundation is crucial for the supporting posts and the cantilever mechanism. Concrete footings are typically used to anchor the posts securely.

Space Considerations: Adequate space is required along the fence line for the gate in its fully open position. This space must be clear of obstructions and have a level surface to accommodate the gate's operation.

Alignment: Proper alignment of the rails and rollers is critical. Misalignment can lead to excessive wear on the mechanism and hinder the gate's operation.

Professional Installation: Due to the complexity of the design and the precision required in installation, professional installation is recommended. This ensures that the gate operates efficiently and safely.

V-Roller Gates
Design Requirements
Track System: The design of V-roller gates includes a ground track that the wheels of the gate roll on. This track must be robust and well-constructed to support the weight of the gate and withstand wear from frequent operation.

Gate Material: Similar to cantilever gates, V-roller gates are commonly made from steel or aluminum. The material must be chosen based on the security needs and environmental conditions of the installation site. Ametco offers a vareity of aluminum and steel infill panel designs to match any application. Visit our Panels page, click on "Gates" under the Applications tab for design ideas.

Rollers: The rollers must be designed to fit snugly within the track, ensuring smooth operation and minimal lateral movement. V-shaped rollers are effective in maintaining the gate's position and alignment during operation.

Installation Requirements
Track Installation: The installation of the ground track requires precise leveling and alignment. The track must be free of debris and well-maintained to prevent operational issues.

Drainage: Proper drainage along the track is essential to prevent water accumulation, which can cause rust or operational hindrance, especially in colder climates where ice can form.

Security Features: Installation of additional security features like automatic locks, entry control systems, and surveillance integration is common with V-roller gates to enhance the security level of the property.

Professional Installation: Similar to cantilever gates, the installation of V-roller gates requires skilled professionals to ensure that the gate operates correctly and safely over time, particularly given the complexity of aligning and maintaining the track system.
Both types of gates have specific design and installation needs that must be met to ensure their longevity and functionality. Choosing the right professionals for installation and maintaining the gate as per manufacturer guidelines are crucial steps for the successful operation of cantilever and V-roller gate systems.
