There are several types of height-restriction barriers, each designed to suit different levels of access control, flexibility, and site usage. Choosing the right type depends on whether you need permanent restriction, occasional access, or automated control.
Main types of height-restriction barriers:
- Fixed height barriers
- Permanently set at a specific clearance (typically 2.0–2.2m)
- No moving parts, making them low maintenance and highly durable
- Ideal for car parks and sites where taller vehicles must always be restricted
- Swing-arm (hinged) height barriers
- Feature a pivoting top beam that can be unlocked and opened
- Allow access for authorised taller vehicles when needed
- Common in commercial sites, service yards, and mixed-use areas
- Removable height barriers
- Can be lifted out or detached completely
- Typically used where access changes occasionally but not frequently
- Suitable for maintenance access or temporary openings
- Adjustable height barriers
- Allow the clearance height to be manually altered
- Useful for sites with varying vehicle requirements or seasonal use
- Less common but valuable in specialist applications
- Automatic or powered height barriers
- Operated via electric or hydraulic systems
- Can integrate with access control (ANPR, keypads, fobs, intercoms)
- Used in high-traffic or higher-security environments where quick, controlled access is required
How to choose the right type:
- Consistent restriction needed? → Fixed barrier
- Occasional tall vehicle access? → Swing-arm or removable
- Frequent controlled access? → Automatic system
- Variable site requirements? → Adjustable barrier
