Stair treads are rarely a round number, and an insert strip cut a few millimetres short leaves a gap that fills with grit and lifts at the end. This is the same 10mm carborundum insert as our 1m, 1.5m and 2m stock lengths, cut here to the exact millimetre you specify between 250mm and 2000mm, tolerance plus or minus 5mm.
A slim 10mm-wide strip of aluminium oxide grit bonded into a resin matrix, set in a carrier that beds into a routed groove or sits on the tread surface. Carborundum is the hardest of the common anti-slip infills: it does not polish out under footfall the way a soft PVC insert eventually does, which is why it is specified for entrances, plant rooms, external steps and any stair that gets walked on in wet boots.
At 10mm it is the discreet option. Two or three parallel strips across a tread give a broad grip band without the visual weight of a single wide insert, and on a narrow going a 10mm strip set back from the edge does not compete with the nosing itself.
Cutting carborundum on site is unpleasant and slow: the grit destroys a fine-toothed blade and the dust is abrasive. Cutting in a workshop keeps the ends square, keeps the grit intact right to the end of the strip, and means the strips arrive ready to bed. On a stair where every going differs, that is the difference between a day of measuring and cutting and an afternoon of fixing.

Measure each tread individually rather than assuming a flight is consistent, and take 3mm to 5mm off a wall-to-wall measurement so the strip drops in without scraping. Set the strips back at least 15mm from the front arris so the nose edge stays intact. The substrate must be clean, dry and free of laitance; bed in a bar of exterior-grade adhesive worked well into the groove, and weight the strip until cured. Custom lengths are made to your figures, so they are non-returnable except for faults.
Where the insert is doing a safety job rather than a decorative one, choose a colour that contrasts in tone with the tread: obsidian on pale concrete, chalk or Portland stone on dark stone. The speckled and marble-effect colours are the ones to pick when the strip should read as part of the floor rather than as a warning line.
Cut lengths are made to order; allow additional working days over a stock length and we will confirm a dispatch date. Standard UK mainland delivery is a flat rate. If your treads sit close to 1m, 1.5m or 2m, the stock listing linked above will reach you sooner.

Works a treat for getting custom sizing at a reasonable cost. I slotted the insert seamlessly into my hallway steps and it’s stayed solid through all sorts of foot traffic. The fact you can cut the any length needed means no annoying spaces along the edges, which is brilliant compared to more rigid options.
Had to fix the worn-out steps at our sleek new office building. This tape was easily cut to fit perfectly along the edges and added a nice touch amidst all the glass doors. Didnt think Id be looking for more so soon, but considering how its withstood a good amount of rain already, Ill probably order again if needed.
Came with all necessary parts and was simple to put into position alongside the pool steps at our complex. The grip underfoot was impeccable, especially on those damp days when everything gets slippery. Nice to have it cut precisely as needed to fit the any unusual lengths we required. Thrilled with how well it stands up against heavy foot traffic too.
Didnt expect much with the delivery, but it came well-packaged and on time. These inserts fit just right when fixed at the library entrance, making access safer without hassle. Would consider ordering again next time for the any projects needing precise fitting.
Fitted it to the edges of our warehouse fire escape months back. The strip looks sharp and hasnt shown any signs of wear despite the heavy industrial use. Handy that it arrived cut precisely to my specification—holds strong, even against the rust creeping at the rails.
Got this for the bustling entrance to our shopping centre. The finish is spot on and enhances the modern look were going for. A neat fit with no gaps, the any stair lengths truly suit every purpose we could need it for, and that adds enormous value.
Remarkably tailored! The way this stair strip was cut to my exact measurements is brilliant value for money. Fits nicely on the stairs, no awkward gaps begging for grime. Installed in a breeze by ourselves, theyve held up wonderfully even with daily use and sunlight streaming in through the windows. Perfect solution without having extra DIY faff around them!
