What materials, finishes and visibility features should be considered (galvanised steel, powder-coat, RAL colours, reflective signs)?

The materials, finishes, and visibility features you choose have a major impact on the performance, longevity, and safety of your height-restriction barrier.

At Aremco Barriers, all our UK-manufactured height barriers are built from heavy-duty galvanised steel, ensuring excellent strength, corrosion resistance, and impact durability in outdoor conditions.

After galvanising, barriers are powder-coated for added weather protection and a smart, professional appearance. Powder coating also allows full colour customisation in any RAL shade — with popular options including:

For maximum visibility and safety, every barrier can be fitted with reflective aluminium height signs (RA1 or RA2 grade), contrasting colour bands, or chevron markings to alert approaching drivers both day and night.

These combined features ensure each barrier remains durable, low-maintenance, and clearly visible, meeting UK car-park and highway safety standards while maintaining a professional finish that complements your site.
