Automatic Sliding Gates vs. Arm Barriers

When it comes to securing vehicle entry points, two of the most common options are automatic sliding gates and arm barriers. Both regulate traffic flow and improve security, but they differ significantly in cost, durability, and use cases.

This guide compares sliding gates and arm barriers so you can decide which is the right fit for your facility.

What Are Automatic Sliding Gates?

Definition

Automatic sliding gates are motorized gates that slide horizontally to open and close, blocking or granting vehicle access.

Best Uses

• Industrial sites and warehouses

• Residential complexes

• Facilities needing full perimeter closure

Cost (2025)

• $7,000 – $15,000 per gate

• Installation: $2,000 – $5,000 depending on size and site conditions

What Are Arm Barriers?

Definition

Arm barriers (or boom barriers) use a mechanical arm that raises and lowers to block or allow passage.

Best Uses

• Parking lots and garages

• Office complexes and gated communities

• Toll booths and transport hubs

Cost (2025)

• Standard automatic models: $2,500 – $4,500

• High-security crash-rated models: $6,000 – $12,000+

• Installation: $700 – $2,000

Key Differences Between Sliding Gates and Arm Barriers

When to Choose Sliding Gates

Advantages

• Full closure of entrances for maximum perimeter protection

• Strong visual deterrence

• Suitable for industrial sites, logistics hubs, and residential complexes

Limitations

• Expensive to purchase and install

• Requires significant lateral clearance

• Slower throughput than arm barriers

When to Choose Arm Barriers

Advantages

• Affordable compared to sliding gates

• Fast and efficient for high-traffic entry points

• Easy to integrate with RFID, biometrics, or license plate recognition

Limitations

• Do not provide full perimeter closure

• Less resistant to forced vehicle entry than crash-rated bollards or gates

FAQ: Sliding Gates vs. Arm Barriers

Can sliding gates and arm barriers be used together?

Yes. Many facilities use arm barriers for daily traffic control and sliding gates for after-hours perimeter closure.

Which option is better for high traffic volume?

Arm barriers — they operate much faster than sliding gates.

Which lasts longer?

Both can last 10–15 years with proper maintenance, but sliding gates have more moving parts and may require more servicing.
