Anti-Slip GRP Stair Nosing - Black
Anti-slip GRP stair nosing strips built to protect the leading edge of a step, reducing the risk of slips and the liability that follows. Made from hard-wearing GRP at just 3mm thick, these nosings fit onto concrete, wood, metal, and stone substrates without posing a trip risk, and install quickly using screws or adhesive. Available in two cross section sizes and a range of lengths to suit different step widths.
How a durable black nosing blends into existing stair finishes
Some staircases already have a dark tread or finish, where a bright or light coloured nosing strip would stand out more than a facilities team wants, even if visibility isn't the primary concern for that particular stair. In these settings, restoring slip protection to the leading edge matters more than adding a contrasting highlight. This nosing strip delivers the same 3 out of 3 rated anti-slip performance as the white version, in a black finish that blends more naturally into darker stair surfaces.
Key Features
-
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.
-
3mm low profile thickness: Fits onto the leading edge of a step without creating a trip hazard.
-
Suitable for concrete, wood, metal, and stone: Installs onto a wide range of existing stair substrates.
-
Screw or adhesive fixing: Installs quickly using either method depending on the substrate and preference.
-
Black finish: Blends into darker stair surfaces where a contrasting colour isn't the priority.

Who is this for
These nosings suit facilities managers, health and safety officers, and maintenance contractors responsible for staircases where the leading edge needs slip protection without necessarily requiring a contrasting highlight colour. They are intended for retrofitting onto existing concrete, wood, metal, or stone stairs across industrial, commercial, and general facilities settings.
Typical applications
- Protecting the leading edge of steps where a discreet black finish suits the existing stair appearance.
- Restoring slip resistance to worn or slippery step edges without changing the overall stair colour scheme.
- Retrofitting anti-slip protection onto existing concrete, wood, metal, or stone stair edges.
- Reducing slip related liability on staircases used by staff, visitors, or the public.
- Supporting stair safety compliance where the leading edge specifically has been identified as a risk.
How to use
Step 1: Measure the width of the stair edge and select the appropriate cross section and length, cutting to fit if required.
Step 2: Clean and prepare the leading edge of the step, removing any loose material.
Step 3: Position the nosing strip along the leading edge, checking alignment before fixing.
Step 4: Secure using screws or a suitable adhesive appropriate to the substrate.
Step 5: Check the strip is firmly seated and doesn't create a trip hazard before returning the stair to use.
Common mistakes
-
Installing the nosing over a poorly prepared or unstable substrate, reducing fixing security.
-
Choosing a cross section that doesn't suit the existing step profile, leaving an uneven finish.
-
Using fixings not suited to the substrate material, such as concrete, wood, metal, or stone.
-
Leaving the strip loosely fixed, creating a trip hazard rather than a secure edge.
-
Assuming the 55mm x 55mm x 3m length available in white is also available in this black range.
Safety
These nosings are rated 3 out of 3 for slip resistance and are designed to protect the leading edge of a step, not to replace a full tread cover where the whole step surface needs treating. Where visibility of the step edge is a specific concern, such as in poorly lit areas, a higher contrast colour like white may be more appropriate than black. Ensure strips are securely fixed using an appropriate method for the substrate material before returning the staircase to use.
Maintenance
Clean periodically to remove dirt, debris, and any surface contamination that could affect grip. Check fixings and strip condition periodically, particularly on external staircases exposed to weather.
Frequently Asked Questions
Q: How slip resistant are these nosings actually rated?
A: The nosings are rated 3 out of 3 for slip resistance, the highest score on the scale used, providing a high-traction finish on the leading edge of a step. This makes them suited to staircases where the edge specifically has become a slip risk.
Q: Why choose black instead of white?
A: Black suits staircases that already have a darker tread or finish, where a bright nosing strip would stand out more than intended. It delivers the same anti-slip performance as the white version, prioritising a blended appearance over a contrasting highlight.
Q: What is this nosing NOT suitable for?
A: These nosings protect the leading edge of a step rather than the full tread surface, so a step that's worn or slippery across its whole width would be better suited to a full stair tread. Where step edge visibility in low light is a specific concern, a higher contrast colour may be more suitable than black.
Q: What cross section sizes are available?
A: These nosings are available in two cross sections, 30mm x 70mm and 55mm x 55mm, across a range of lengths. This black range does not include the 55mm x 55mm x 3m length offered in white, so checking the size comparison table before ordering confirms availability.
Q: How are these nosings actually fixed in place?
A: The nosings can be installed using screws or a suitable adhesive, with the method chosen based on the existing substrate, whether concrete, wood, metal, or stone.
Q: Can these nosings be cut to fit a specific step width?
A: Yes, the nosings can be trimmed to fit individual step widths where a standard length doesn't match exactly.
