{"product_id":"aluminium-stair-nosing-30x30mm-ribbed-anodised","title":"Aluminium Stair Nosing 30x30mm Ribbed Anodised Step Edge Trim","description":"\u003cp\u003eWhen the front edge of a stair tread starts to go — carpet fraying at the nose, laminate chipping where every foot lands — a slim aluminium angle is usually the least disruptive repair available. This 30 x 30mm nosing screws down over the finished tread and wraps the riser below it, covering the damaged edge and taking the traffic from that point on. Fine ribbing is extruded into both faces, so the top gives grip underfoot and the front gives a visible edge marker on the way down. At 30mm on each face it is a domestic-scale profile: it tidies a staircase rather than dominating it. Gold and silver anodised finishes, 1.0m and 2.0m lengths, fixing screws supplied.\u003c\/p\u003e\n\n\u003ch2\u003eWhy it works\u003c\/h2\u003e\n\n\u003ch3\u003eAn equal-sided angle covers two surfaces at once\u003c\/h3\u003e\n\u003cp\u003eThe profile is a true right angle with 30mm on the tread and 30mm on the riser, so a single length protects the horizontal wear face and the vertical edge that takes kicks and vacuum knocks. A tread-only strip leaves the riser exposed; this one does not, and because both legs are the same depth it reads as a deliberate detail from above and from below.\u003c\/p\u003e\n\n\u003ch3\u003eRibbing on both faces, not just the tread\u003c\/h3\u003e\n\u003cp\u003eClose-pitched ribs run the full length of the top face and the front face, and the lower lip of the front face is finely serrated. The ribbing on the tread is what your foot meets, breaking up a smooth metal surface that would otherwise be slick under a leather sole. The ribbing on the riser catches light differently from the flat floor covering either side of it, which helps the edge of each step stand out. The manufacturer publishes no slip-resistance rating, R value or pendulum figure for this line — see the specification table below.\u003c\/p\u003e\n\n\u003ch3\u003eAnodising rather than paint\u003c\/h3\u003e\n\u003cp\u003eThe gold and silver finishes are anodised, meaning the colour sits in a hardened oxide layer grown into the aluminium rather than in a coating laid on top. Anodising does not chip off the leading edge the way a lacquer does, and it keeps its appearance under cleaning.\u003c\/p\u003e\n\n\u003ch2\u003eWhere it's used\u003c\/h2\u003e\n\u003cp\u003eDomestic staircases are the common case: a carpeted flight where the nosing has flattened, a laminate or LVT stair that was laid without a proper edge trim, or a single step between rooms that keeps catching toes. It is also used in flats, HMOs and small offices where a communal stair needs tidying between tenancies without taking the covering up. The manufacturer lists it for carpet, laminate and LVT.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTread face\u003c\/td\u003e\n\u003ctd\u003e30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRiser face\u003c\/td\u003e\n\u003ctd\u003e30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProfile\u003c\/td\u003e\n\u003ctd\u003eStraight-edged equal-sided angle\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eAnodised aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFinishes\u003c\/td\u003e\n\u003ctd\u003eGold, Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLengths\u003c\/td\u003e\n\u003ctd\u003e1.0m, 2.0m\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSurface\u003c\/td\u003e\n\u003ctd\u003eRibbed on both the tread and the riser face\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInsert or channel\u003c\/td\u003e\n\u003ctd\u003eNone — this is a solid profile with no PVC or carborundum insert\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFixing\u003c\/td\u003e\n\u003ctd\u003eScrew-fixed through pre-drilled countersunk holes; screws supplied\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFloor coverings\u003c\/td\u003e\n\u003ctd\u003eCarpet, laminate, LVT (manufacturer stated)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSlip resistance\u003c\/td\u003e\n\u003ctd\u003eNot published for this line\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFire rating\u003c\/td\u003e\n\u003ctd\u003eNot published for this line\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStandards and approvals\u003c\/td\u003e\n\u003ctd\u003eNone published for this line.

Measure the full width of the tread, including any string or skirting return, and work out whether 1.0m or 2.0m wastes less across the whole flight. A standard domestic stair is usually 850–900mm wide, so the 1.0m length covers one step with a trim cut; the 2.0m length suits wider communal stairs, or lets you take two narrow steps from one bar with a single cut.\u003c\/p\u003e\n\u003cp\u003eThen the finish. Silver is the safer choice against grey and cool-toned carpets, LVT and painted white risers. Gold sits better with oak, walnut and warm beige, and is the one people reach for on a period staircase with brass stair rods already fitted.\u003c\/p\u003e\n\u003cp\u003eCheck the depth before you order. Thirty millimetres is a light-duty domestic dimension. If the flight is a public or commercial stair, if you need a defined contrasting nose for a building-regulations submission, or if you want a replaceable anti-slip insert, this is not the profile — look at our heavy-duty and insert-carrying nosings instead.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation, use and care\u003c\/h2\u003e\n\u003cp\u003eFit it over the finished floor covering, not underneath it. Cut to width with a fine-tooth hacksaw or a mitre saw with a non-ferrous blade, then deburr the cut end with a file. Offer the length up, mark through the pre-drilled countersunk holes, drill and plug the tread if you are fixing into concrete or stone, and drive the supplied screws down until the heads sit flush in the countersinks. Take the ends in a few millimetres from the string so the profile does not foul the skirting. Afterwards it needs nothing more than a damp cloth — avoid abrasive creams and bleach-based cleaners, which will dull an anodised surface.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003ch3\u003eDoes this go on top of the carpet or underneath it?\u003c\/h3\u003e\n\u003cp\u003eOn top. It is a retro-fit profile: you fit the covering first, then screw the nosing down over the finished tread edge. That is why it can be fitted to an existing staircase without lifting anything.\u003c\/p\u003e\n\n\u003ch3\u003eAre the fixings included?\u003c\/h3\u003e\n\u003cp\u003eYes — the manufacturer supplies installation screws with the profile. Wall plugs for masonry substrates are not included, so add those if you are fixing into concrete or stone rather than timber.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use it outside?\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer does not list this profile for external use and publishes no weathering or exterior rating for it. It is specified for interior floor coverings — carpet, laminate and LVT. If you need an outdoor step edge, choose a profile that is sold and rated for it.\u003c\/p\u003e\n\n\u003ch3\u003eIs it DDA compliant or rated for slip resistance?\u003c\/h3\u003e\n\u003cp\u003eNo such claim is published for this line. There is no pendulum test value, R value or Part K or Part M statement available from the manufacturer, and we do not make one on their behalf. It is a domestic edge-protection trim with a ribbed surface, not a rated anti-slip nosing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between gold and silver?\u003c\/h3\u003e\n\u003cp\u003eFinish only.
