When specifying or installing a height-restriction barrier, a few common errors can lead to safety risks, property damage, and compliance issues. Avoiding these mistakes will help ensure reliable long-term performance.
- Incorrect Height Selection – Setting the clearance too low can restrict normal vehicle access, while too high defeats the purpose of the barrier. The standard UK clearance for most car parks is 2.0 – 2.2 m.
- Poor or Missing Signage – Inadequate or faded signs cause confusion and collisions. Always fit reflective RA1/RA2 aluminium height signs in both metric and imperial units at the barrier and approach routes.
- Inadequate Warning Distance – Drivers need early visual warnings. Install advance warning signs before tight entrances, bends, or ramps.
- Not Considering Larger Vehicles – Service vans, refuse vehicles, or emergency access must be factored in. Consider a swing-arm or removable design for occasional tall-vehicle entry.
- Improper Installation or Foundations – Shallow or uneven foundations reduce stability and shorten lifespan. Posts should be embedded 300–500 mm into concrete or fixed to pre-levelled pads.
