Anti-Slip GRP Stair Treads - Black/Yellow
Anti-slip GRP stair treads built to make a whole step slip-resistant, combining full tread coverage with a contrasting black and yellow finish that highlights the leading edge for high visibility. Suited to concrete, steel, stone, and wood staircases, these treads won't rot or twist and are rated 3 out of 3 for both slip and wear resistance. Available in six lengths that can be cut to size on site, and secured using stainless steel fixings or a suitable adhesive.
How a high visibility yellow edge improves stair safety
A worn or plain coloured stair tread can be difficult to judge accurately in busy industrial settings, external stairs, or areas where hazard awareness needs to be immediate rather than assumed. Yellow is widely recognised as a hazard warning colour, making it a common choice for marking step edges where visibility and caution both matter, not just poor lighting. This tread combines a 3 out of 3 rated anti-slip surface with a contrasting black and yellow finish, addressing both grip and clear hazard marking in one product.
Key Features
-
Full tread coverage: Covers the entire step surface including the nose and leading edge, rather than just a narrow edge strip.
-
Contrasting black and yellow finish: Highlights the leading edge of the step using a widely recognised hazard warning colour.
-
Anti Slip Rating 3: Tested to a 3 out of 3 slip resistance rating, the highest score on the scale used.
-
Wear Resistance Rating 3: Tested to a 3 out of 3 wear resistance rating under accelerated abrasion testing.
-
Suitable for concrete, steel, stone, and wood: Fits a wide range of existing staircase materials without needing to replace the underlying structure.
-
Won't rot or twist: Holds its shape and condition over time, unlike timber alternatives exposed to damp conditions.

Who is this for
These treads suit facilities managers, health and safety officers, and industrial maintenance teams responsible for staircases where both slip resistance and clear hazard marking are needed, particularly in industrial sites, warehouses, and external staircases. They are intended for retrofitting onto existing concrete, steel, stone, or wood stairs without replacing the underlying structure.
Typical applications
-
Refreshing slip resistance and hazard visibility on staircases in industrial and warehouse settings.
-
Marking step edges clearly using widely recognised yellow hazard colouring.
-
Retrofitting anti-slip, high visibility protection onto concrete, steel, stone, or wood stairs.
-
Supporting health and safety compliance on external or heavily used staircases.
-
Providing full-width slip protection across the whole tread with a clear visual hazard reference.
How to use
Step 1: Measure the width of the stair tread and select the closest available length from the six offered.
Step 2: Clean and prepare the existing step surface, removing any loose material or old coating.
Step 3: Position the tread across the full step surface, checking alignment with the nose and leading edge.
Step 4: Secure using stainless steel fixings or a suitable adhesive appropriate to the existing surface material.
Step 5: Check the tread is firmly seated and doesn't create a trip hazard before returning the staircase to use.
Common mistakes
-
Installing the tread over a poorly prepared or unstable existing surface, reducing fixing security.
-
Cutting the tread to a length that leaves gaps or overhangs at either edge of the step.
-
Using fixings or adhesive not suited to the existing surface material.
-
Leaving the tread loosely fixed, creating a trip hazard rather than a secure walking surface.
-
Assuming every length available in the Black or Black/White ranges is also available here, rather than checking the length comparison table.
Safety
These treads are rated 3 out of 3 for slip resistance, the highest score on the scale used, and combine this with a widely recognised yellow hazard colour to improve step visibility. Ensure treads are securely fixed using an appropriate method for the existing surface material before returning the staircase to use.
Maintenance
Clean periodically to remove dirt, debris, and any surface contamination that could affect grip or obscure the contrasting finish. Check fixings and tread condition periodically, particularly on external staircases exposed to weather.
Frequently Asked Questions
Q: How slip resistant are these treads actually rated?
A: The treads are rated 3 out of 3 for slip resistance, the highest score on the scale used, based on testing that includes ASTM C1028-89 and DIN 51130/51097 alongside customer feedback. This makes them suited to staircases with a high risk of slipping, including persistently wet conditions.
Q: Why yellow rather than white for the contrasting edge?
A: Yellow is widely recognised as a hazard warning colour in industrial and site environments, making it a common choice for marking step edges where immediate hazard awareness matters as much as visibility in low light. The black/white version suits general visibility needs, while black/yellow leans more toward hazard marking.
Q: What is this tread NOT suitable for?
A: These treads are designed for stair tread applications rather than general flooring, and a specific fixing method should be confirmed for the existing surface material before installation. Chemical resistance covers certain chemicals rather than every possible substance, so specific compliance requirements should be confirmed against the product datasheet.
Q: What lengths are available in this Black/Yellow finish?
A: This colourway is available in 1m, 1.2m, 1.5m, 2m, 3m, and 3.6m lengths, including a 3.6m option not offered in the Black or Black/White ranges. Checking the length comparison table before ordering confirms the best fit for the stair width being covered.
Q: How are these treads actually fixed in place?
A: The treads can be secured using stainless steel fixings or a suitable adhesive, with the method chosen based on the existing surface material, whether concrete, steel, stone, or wood.
Q: Can these treads be cut to fit a specific stair width?
A: Yes, the treads can be cut to length on site to suit individual stair widths within the available length range.
