The materials, finishes, and visibility features you choose have a major impact on the strength, lifespan, and safety of a height-restriction barrier—especially in outdoor, high-traffic environments like car parks and industrial sites.
Materials (core structure)
- Galvanised steel (industry standard)
- Offers excellent strength, impact resistance, and durability
- Hot-dip galvanised to BS EN ISO 1461 for long-term corrosion protection
- Ideal for car parks, commercial sites, and exposed environments
- Alternative materials (less common)
- Aluminium or lighter materials may be used in specialist cases but generally lack the strength required for heavy-duty applications
Finishes (protection & appearance)
- Galvanised finish (base protection)
- Provides a zinc coating that protects against rust and weathering
- Suitable for long-term outdoor use
- Powder-coated finish (optional upgrade)
- Adds an extra protective layer and improves appearance
- Available in any RAL colour to match branding or surroundings
- Helps extend lifespan and reduce maintenance
Popular RAL colours include:
- RAL 1021 (Traffic Yellow) – High visibility and safety
- RAL 9005 (Black) – Clean, modern look for commercial sites
- RAL 6005 (Green) – Blends into landscaped or rural settings
Visibility features (critical for safety)
- Reflective height signage (RA1 / RA2 grade)
- Clearly displays the maximum clearance height
- Designed for day and night visibility
- Reflective strips or bands
- Improve awareness of the barrier in low-light conditions
- Chevron markings or contrasting colours
- Help draw attention to the barrier, reducing the risk of vehicle strikes
- Hanging nudge bars or chains (optional)
- Provide an early warning to drivers before they reach the main beam
Why it all matters
Combining the right materials and finishes ensures your barrier is:
- Durable and corrosion-resistant
- Low maintenance over its lifespan
- Clearly visible to drivers, reducing accidents
- Compliant with UK safety expectations and best practice
At Aremco Barriers, all of our UK-manufactured height-restriction barriers are built from heavy-duty galvanised steel and can be powder coated in any RAL colour, with high-visibility reflective signage and safety features as standard. This ensures every installation delivers long-term performance, maximum visibility, and professional appearance across a wide range of environments.
