Some step edges need more than a token trim over the corner. Where a tread is thick, where the nose has been chipped back, or where a tiled step has lost its arris, a shallow profile just highlights the damage it is supposed to hide. This one has a 40mm front face — nearly as deep as the 45mm top plate is wide — so it wraps a long way down the riser and covers the whole exposed edge in one piece. The top is ribbed across its full width for grip, and the profile is screw-fixed through holes that arrive already drilled and countersunk. Silver anodised aluminium, 2mm wall, in 1.0m and 2.5m lengths.
Most surface-mount stair nosings drop 20–25mm, which is enough to cap a neat edge on a thin floor covering and not much more. At 40mm this one keeps going: it covers the full thickness of a tiled tread plus its adhesive bed, or a chipped concrete arris, or the cut edge of a thick engineered board, and still lands flat on the riser below. If you have measured your step nose and a standard trim comes up short, this is the profile that closes the gap.
It sits on top of the finished tread rather than being bedded into it, so it goes onto a staircase that is already tiled, laminated or boarded. Nothing has to come up. The trade-off is honest and worth knowing before you order: the 2mm plate stands 2mm proud of the tread surface, so there is a small lip at the front of each step. If you need a finish that is completely flush with the floor, you need a tile-in profile fitted during the floor installation, not this.
Fine grooves run the full 45mm width of the top face, breaking up what would otherwise be a smooth metal surface at the point where a foot is most likely to skid. It has a grooved anti-slip top surface. Anodising hardens the outer skin of the aluminium rather than coating it, so the finish does not flake off where feet land.
It suits laminate, vinyl, tile and wooden stairs in commercial and domestic settings, including schools, offices and residential properties. In practice it earns its keep on tiled entrance steps and communal stairs where the nose is deep, and on refurbishment work where existing edges are already damaged. It is not listed for carpeted stairs — the deep face is designed to sit against a hard riser, not to clamp a pile edge.

| A note on the dimensions | The product data and dimensioned drawing all give 45 x 40 x 2mm, and that is what we list. Its written description says 44mm wide with a 38mm drop. We have raised the discrepancy with them; allow a millimetre either way on a tight fit |
Is 40mm the face you want? Measure the exposed front edge of your step from the top surface down to where the riser starts. If that is 30mm or more, this is the profile. If it is 20mm or so, our 44 x 23mm ribbed nosing is the slimmer version of the same idea, comes in silver or gold and in five lengths, and will look less heavy on a domestic flight.
Length. A standard domestic stair is 750–900mm wide, so the 1.0m covers one step with a trim. The 2.5m is the one to buy for a flight: cut into two 1.2m pieces for wide commercial stairs, or three shorter pieces for a domestic run, which works out cheaper per step than buying 1.0m lengths and wasting the offcuts. Measure every tread — stair widths are rarely identical top to bottom.
Cut to length with a hacksaw and a fine metal blade, or a chop saw with a non-ferrous blade, and file the cut end smooth. Offer the profile up with the deep leg flat against the riser and the ribbed plate flat on the tread, then mark through the existing countersunk holes. Drill pilot holes, plug them if you are fixing into tile, concrete or masonry rather than timber, and screw down until the heads sit flush in the countersinks. Take care drilling through tile: use a tile bit and low speed, or you will crack the tread you are trying to protect. Clean with a damp cloth and mild detergent; avoid abrasive pads and solvent cleaners, which dull anodising permanently.
No. It is a surface-mount profile: it screws down on top of the finished tread and the deep leg covers the front edge and the top of the riser. That is what makes it useful on refurbishment work, where a tile-in nosing would mean lifting and relaying the floor.
The profile arrives pre-drilled and countersunk, but fixings are not confirmed as included in the box, so we will not promise they are. Screws and plugs for tile, concrete or timber are cheap and readily available — or contact us before you order and we will confirm what is in the pack.
No published one. The top face is grooved to act as an anti-slip surface, but no pendulum value, PTV, R rating or equivalent test figure is published for this profile. If your specification calls for a certified slip value, ask us and we will point you at a profile in the range that publishes one.
We would not recommend it. This profile is suited to laminate, vinyl, tile and wooden stairs only. The deep front face is shaped to sit against a hard riser; for carpet you want a nosing designed to hold and cover a pile edge.
2mm — the thickness of the plate. That is a small lip at the front of each step, which is normal for any surface-mount nosing and is the price of being able to retrofit without lifting the floor. If you need a dead-flush finish, specify a tile-in profile and fit it while the floor is being laid.
Choose your length above. The price shown is for a single length, and you will need one per step unless you are cutting a 2.5m bar down. Everything is dispatched from UK stock. If you are working to a drawing and need the exact section confirmed, or you want a sample before committing to a whole flight, contact us before you order.

Job done when it comes to adding stability. These anti-slip trims made my visits to the local library safer and more convenient without breaking the bank. The weight of each piece testified to their durability, ensuring that these are built to handle a fair bit of use.

Had to sort out the metal steps in the factory, as they were starting to look a bit worse for wear. The appeal of this aluminium piece caught my eye because its bold finish adds an unexpected touch of elegance amidst all that machinery and clatter. Up close, it doesn’t distort or show imperfections, which is rather impressive given the heavy-duty setting its faced with each day.

Delivered promptly and exactly what I needed to sort out my kitchen doorstep. Weve always had a bit of water spilling over from the sink when cooking, and this aluminium stair nosing really grips well underfoot, even when the floor gets a bit slippy with all that hustle!

Wasnt sure at first how sturdy this would be, but the packaging was reassuringly solid and everything arrived intact. Used it on a concrete stair edge in a busy university lecture hall, and so far, its keeping its smart appearance well under constant footfall. The stair nosing fits neatly and doesnt call attention to itself — much better than looking at frayed edges every day.

Tried installing these nosings a few months back, and theyve held up surprisingly well. Admittedly, pulling them out the box left me halfway between impressed and nonplussed—it’s just a lot of metal trim at the end of the day. No noteworthy scratches or dents, though they’ve seen their fair share in this busy hallway. Seriously thinking Ive made a wise choice with how this ones bearing fatigue over time.

Got this to tidy up the hotel lobby steps after wear and tear, and it blends in brilliantly with the tiles while keeping everything safer. The stair nosing is a clean fit and really sharpens up the look of the staircase—plus installation was surprisingly quick considering what Id expected.

Surprisingly robust. Had to sort out the chipped edges on our outdoor stone steps leading up to the library, and this metal trim fit the bill snugly. Cutting it down to size was straightforward enough with a hacksaw, although I did have a couple of words with it when getting the angle right! Once on, it lined up like an old friend along that edge, with enough grip to keep even the clumsiest footsteps secure. Feels like it’ll hold its place for years even with all that foot traffic heading through.
