Standard Duty Anti-Slip GRP Stair Treads – 10-Year Guarantee | Fire Resistant, Lightweight, Easy Install | Non-Slip Fibreglass Stair Covers

Upgrade any staircase instantly with our Standard Duty Anti-Slip GRP Stair Treads — the trusted UK-made solution for outstanding slip resistance in commercial, industrial and residential environments. Manufactured from high-strength Glass Reinforced Plastic (GRP) fibreglass with an integrated high-traction gritted surface, these covers fit directly over existing steps to eliminate the risk of slips, trips and falls on worn, smooth or damaged stairs — indoors and outdoors.

Independently tested to BS EN 16165:2021, achieving low slip potential ratings, and classified A2fl-s1 for fire performance under EN 13501-1, these treads meet the safety standards demanded by health & safety officers, building managers and facility contractors across the UK. They also support compliance with DDA (Disability Discrimination Act) accessibility requirements, making them ideal for public-access buildings, schools, hospitals, retail environments and more.

Whether you're managing a fire escape, a factory staircase, a leisure centre, a block of flats or a garden deck, these treads provide a long-lasting, low-maintenance safety solution that outperforms paint, tape and rubber alternatives.

Colour & Accessibility Options

Visual contrast is critical for stair safety, particularly for users with visual impairments. Our treads are available in a choice of solid colours and two-tone contrast combinations, each with defined Light Reflectance Values (LRVs) to help meet DDA guidance on visual contrast for partially sighted users. Whether you need a subtle grey for a corporate environment or a bold black and yellow for a high-visibility industrial setting, there is a colour to suit every application.

Installation Guide

Installing our GRP stair treads is a straightforward process suitable for contractors and competent DIYers alike. Measure and cut the tread to your required length using an angle grinder or circular saw with a masonry or metal cutting blade. Position the tread over the existing step, drill pilot holes through the pre-marked fixing positions and secure with colour-matched stainless steel Pozi screws. No adhesive or specialist preparation is needed for most applications. Full installation guidance is available upon request.

Frequently Asked Questions

Can these treads be cut to a custom length?
Yes. GRP stair treads can be cut to any required length on site using standard cutting tools. Choose the nearest size above your requirement and cut to fit.

Are these treads suitable for outdoor use?
Yes. The GRP material is fully UV stable, weatherproof and will not rust, rot or degrade outdoors. They are equally suitable for indoor and outdoor staircases including fire escapes, external steps and marine environments.

Do they comply with DDA accessibility requirements?
Yes. The treads are available in colour combinations with sufficient Light Reflectance Value (LRV) contrast to help satisfy DDA guidance for partially sighted users. Contrasting nosing colours include yellow, white and orange.

What fixing screws are recommended?
We recommend colour-matched stainless steel Pozi screws for a clean, professional finish that resists corrosion. These are available separately.

What is the guarantee period?
These treads carry a 10-Year Guarantee against manufacturing defects, giving you complete confidence in long-term performance.

Are they safe for use near electrical equipment?
Yes. GRP is a non-conductive material, making these treads safe for use in plant rooms, switchgear areas and around electrical installations.
