{"product_id":"aluminium-stair-nosing-45x40mm-surface-mount","title":"Aluminium Stair Nosing 45x40mm Surface Mount Anti-Slip Step Edge Trim","description":"\u003cp\u003eSome 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy it works\u003c\/h2\u003e\n\n\u003ch3\u003eThe 40mm face is the whole point\u003c\/h3\u003e\n\u003cp\u003eMost 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.\u003c\/p\u003e\n\n\u003ch3\u003eRetrofit, not rebuild\u003c\/h3\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\n\u003ch3\u003eRibbed and anodised\u003c\/h3\u003e\n\u003cp\u003eFine 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. The supplier describes it as 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhere it is used\u003c\/h2\u003e\n\u003cp\u003eThe supplier lists it for laminate, vinyl, tile and wooden stairs in commercial and domestic settings, and names 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.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProfile type\u003c\/td\u003e\n\u003ctd\u003eSurface-mount angle (L-shaped) stair nosing — screw-fixed, retrofittable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop plate\u003c\/td\u003e\n\u003ctd\u003e45mm front to back, grooved across the full width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront face \/ drop\u003c\/td\u003e\n\u003ctd\u003e40mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWall thickness\u003c\/td\u003e\n\u003ctd\u003e2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial and finish\u003c\/td\u003e\n\u003ctd\u003eAnodised aluminium, silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLengths\u003c\/td\u003e\n\u003ctd\u003e1.0m (100cm) and 2.5m (250cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFixing\u003c\/td\u003e\n\u003ctd\u003eScrew-fix through pre-drilled, countersunk holes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFixings supplied\u003c\/td\u003e\n\u003ctd\u003eNot stated by the supplier — ask us to confirm before ordering if you need them in the box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable floor coverings\u003c\/td\u003e\n\u003ctd\u003eLaminate, vinyl, tile and wood (supplier stated).

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.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation, use and care\u003c\/h2\u003e\n\u003cp\u003eCut 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.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eDo I have to remove the existing floor covering to fit it?\u003c\/summary\u003e\n\u003cp\u003eNo. 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.
