Boom barrier type depends on lane width, overhead height and whether you need extra deterrence.
| Factor | Straight / Telescopic | Folding / Fence |
|---|---|---|
| Lane width | Straight for standard lanes, telescopic for wide lanes | Folding works where height is limited |
| Headroom | Needs vertical clearance for straight arms | Folding arms fit low ceilings |
| Deterrence | Basic vehicle control | Fence style discourages walking under the arm |
| Wind | Light arms catch little wind | Fence and advertising arms catch more wind |
Our verdict
Match arm style to lane width and headroom, then pick speed and access control for your traffic.
