Types of Security Gates

High-Security Gate Buying Guide for Commercial & Industrial Organizations

Security gates play a crucial role in industrial and restricted-access facilities, ensuring that only authorized individuals or vehicles can enter. These automatic security gates are typically installed at the main entrance, controlling access to specific areas. In larger facilities, secondary gates may be placed inside to manage access to sensitive zones. For example, in a parking garage, the main gate allows entry, while an inner gate restricts access to employee-only parking spaces.

Common Applications for Commercial Security Gates

Security gates are widely used across various industries. They ensure that only authorized personnel and vehicles can access certain premises. TYMETAL specializes in providing security gates for facilities such as:

• Airports and seaports
• Public utilities
• Industrial/commercial factories
• Military bases and border stations
• Water treatment and chemical plants
• Railroad depots, crossings, and train yards
• Municipal authorities and transportation terminals
• Schools & universities

While most commonly found in commercial settings, security gates are also used in some residential areas, such as exclusive condominium complexes and private neighborhoods. However, their purpose differs from that in industrial environments. Residential gates mainly aim to prevent unauthorized access by outsiders, whereas industrial gates are designed to control access to critical infrastructure, machinery, and restricted zones.

Commercial vs. Residential Security Gates

Commercial and residential facilities have different needs when it comes to perimeter security. Commercial facilities often require more robust, high-speed solutions due to higher traffic volumes, while residential gates focus on convenience and aesthetics. Commercial gates are typically made of aluminum, which is durable, lightweight, and resistant to corrosion, making them ideal for long-term use with minimal maintenance.

Which Security Gate Should I Choose?

Choosing the right security gate involves considering several factors, including space availability, traffic volume, and ease of operation. Common options include cantilever slide gates, bi-folding gates, and swing gates. Each has unique advantages depending on your facility's requirements.

Key considerations when selecting a gate include:

• Space and opening size: Some gates open sideways, others lift vertically. Ensure the chosen design fits your available space and accommodates the expected vehicle size.
• Frequency and speed: High-traffic areas benefit from faster, more reliable systems that reduce wait times and improve efficiency.
• Operator and access control: Pair your gate with a compatible opener and access system, such as keycard readers or digital locks, to enhance security and convenience.

Do I Need an Electric Gate?

Electric security gates offer significant benefits over manual systems, especially in large facilities with frequent traffic. They save time, reduce staffing needs, and increase productivity. However, they come with higher initial costs and require regular maintenance. If you're unsure about the best option for your business, contact TYMETAL for expert guidance.

Different Types of Security Gates

There are five common types of high-security gates used for vehicular access:

1. Slide Gates (V Groove, Cantilever, Overhead)
2. Swing Gates
3. Vertical Lift Gates
4. Vertical Pivot Gates
5. Bi-Folding Gates

1. Slide Gates

Cantilever Slide Gate

The industrial cantilever slide gate is ideal for large-scale applications. It slides horizontally without requiring a ground track, making it suitable for all weather conditions. This type of gate is often used in industrial and commercial sites where space is limited.

“V Groove” Rolling Slide Gate

This gate uses a “V” shaped ground track and is ideal for areas with limited space. It requires less storage space when open but may be harder to maintain in snowy or icy conditions.

Aluminum vs. Steel Cantilever Gates

Aluminum is preferred for cantilever slide gates due to its lightweight, strength, and resistance to rust. Steel, while strong, is heavier and less suitable for this application. Aluminum gates require less maintenance and are more durable in harsh conditions.

Cantilever Counterbalances

Cantilever gates use counterbalance sections to support the gate when open or closed. These sections help stabilize the gate and make it easier to operate. TYMETAL’s standard counterbalance is 50% of the opening width, offering enhanced stability and performance.

An added advantage of aluminum cantilever gates is the absence of friction and exposure to the elements, making them safer and more reliable than other designs. The enclosed track prevents dirt, snow, and ice from interfering with operation, ensuring smooth performance in all weather conditions.

Overhead Slide Gate

Overhead slide gates use an overhead beam to support the gate panel, allowing it to roll back and forth. They are ideal for areas with limited ground space but may create overhead restrictions. These gates are often used in industrial settings where space is a concern.

2. Swing Gates

Swing gates open like a door and are typically used in areas where space is not a constraint. They can swing inward or outward and are often paired with automated operators. However, they can pose safety risks if not properly managed, especially in unmanned areas.

3. Vertical Lift Gates

Vertical lift gates move upward to open, making them ideal for compact spaces. They do not require front or side clearance, making them a great choice for areas with limited space. These gates are commonly used in industrial settings where quick access is needed.

4. Vertical Pivot Lift Gates

Vertical pivot gates rotate upward at one corner, making them ideal for areas with limited side space. They are often used in industrial settings where overhead clearance is not an issue. However, they may not be suitable for very wide openings.

5. Bi-Folding Gates

Bi-folding gates fold into two panels and are ideal for areas with limited space. They are fast and efficient, making them perfect for high-traffic areas. However, they are typically limited to openings of 20 feet or less.

Pedestrian Security Gates

In addition to vehicular gates, pedestrian access points should also have secure gates. Pedestrian gates, such as swing gates and portals, ensure that only authorized individuals can enter. These gates are essential for maintaining the security of a facility and preventing unauthorized access.

Pedestrian Swing Gates

Pedestrian swing gates function similarly to doors, opening outward to allow one person at a time to pass through. They are commonly used in entrances where space is available and security is a priority.

Pedestrian Portals

Pedestrian portals combine a swing gate with a turnstile, providing secure access for high volumes of foot traffic. These systems are ideal for places like airports, shopping centers, and public buildings where controlled access is required.

Other Security Devices

Various accessories, such as intercoms, surveillance cameras, and access control systems, can be integrated with security gates to enhance overall security. Crash barriers and bollards are also used to protect against unauthorized vehicle access and improve safety in industrial and commercial areas.

Bollards

Bollards are posts that prevent vehicles from entering pedestrian zones or restricted areas. They are often used in urban settings, around storefronts, and near buildings to ensure the safety of people and property.

Crash Beams/Barrier Arms

Barrier arms are simple devices used to control vehicle access. While they are not as secure as other gate types, they are effective in managing traffic flow. Crash beams, on the other hand, are tested to stop vehicles and are used in high-security areas where safety is a primary concern.

How to Choose the Right Kind of High-Security Gate

When choosing a security gate, consider factors such as available space, traffic volume, and gate opening size. Ask yourself how much space you have, what kind of vehicles will be using the gate, and how often the gate will be used. These questions can help guide you in selecting the best option for your facility.

How Much Space Do You Have Available?

Facility location plays a major role in determining the type of gate you can install. Urban areas may have limited space, while rural locations may offer more flexibility. Consider the available space for gate installation and the dimensions of the opening you need.

How Wide Must Your Gate Opening Be?

The size of your gate opening depends on the type of vehicles that will pass through. Heavy trucks require larger openings than cars or vans. Ensure your gate is sized appropriately to accommodate the largest vehicles you expect to use it.

How Much Gate-Weight Can You Manage?

The weight of a gate depends on its size and material. Heavier gates may require stronger operators and more robust support structures. Consider the weight of the gate and how it will affect operation and maintenance.

How Fast Must a Gate Move to Satisfy Your Traffic Flow?

The speed of a gate depends on the type of operator and the size of the opening. Vertical lift gates open quickly, while slide gates may take longer. Safety regulations also dictate maximum speeds, especially for public access areas.

How Many Times Will the Gate Cycle Open and Close Per Day

Frequency of use affects the durability and reliability of a gate. High-cycle applications require more robust systems to avoid breakdowns and maintenance issues. Choose a gate that can handle the expected number of cycles per day.
