{"product_id":"aluminium-stair-corner-trim-28x28mm-inner-corner-5mm-lvt","title":"Aluminium Stair Corner Trim 28x28mm – Inner Corner for 5mm LVT","description":"\u003cp\u003eOn a staircase this is the trim that finishes the back of the tread, where the LVT turns up into the riser above it, and the foot of the flight where the floor meets the first riser. It does exactly the same job anywhere else a vinyl floor runs into a vertical face, which is why it also earns its keep along a wall, a plinth or an upstand. Wherever that junction falls, it is where a click floor looks its worst: a sawn plank edge, a shadow gap, and an exposed core that takes up mop water. This anodised aluminium internal corner profile closes it properly. The 28 mm base leg is screwed down to the substrate and disappears under the flooring, the 5 mm recess takes the plank edge, and the 28 mm upright leg covers the vertical face above it. What you are left with is a slim metal band and one fine rounded bead, with no cut edge showing anywhere along the run. One thing to be clear about before you order: this is the inside-angle profile, not the tread-edge nosing that wraps the front of a step. On a stair job the two are usually bought together.\u003c\/p\u003e\n\n\u003ch2\u003eWhy it works\u003c\/h2\u003e\n\n\u003ch3\u003eThe plank edge is captured, not just covered\u003c\/h3\u003e\n\u003cp\u003eThe 5 mm recess is the whole point of the section. The flooring slides in underneath the lip, so the profile holds the edge down as well as hiding it. A trim that simply sits on top of a finished floor depends entirely on its adhesive, and that is what lifts first under a mop head or a trolley wheel. This one is fixed through the substrate before the last plank goes in, so the joint does not rely on glue at all.\u003c\/p\u003e\n\n\u003ch3\u003eExtruded aluminium holds its line\u003c\/h3\u003e\n\u003cp\u003eAn aluminium extrusion stays straight over a 2.7 m run in a way a flexible PVC trim does not, which matters on a long wall or a wide landing where any waver is read against the skirting line above it. The anodised finish is an integral oxide layer grown into the surface rather than a paint film sprayed onto it, so the scuffing that floor-level trims inevitably take does not chip away and leave bright metal showing through in a different colour.\u003c\/p\u003e\n\n\u003ch3\u003eKnurled inner faces\u003c\/h3\u003e\n\u003cp\u003eBoth inner faces carry fine parallel knurling. It gives adhesive something to key into if you choose to bed the profile as well as screw it, which is worth doing on a substrate that will not hold a fixing reliably.\u003c\/p\u003e\n\n\u003ch2\u003eWhere it is used\u003c\/h2\u003e\n\u003cp\u003eThe supplier lists this profile for stairs, hallways, landings and kitchens, in both commercial and residential work. On a staircase it goes in the angle at the back of each tread and at the foot of the flight. Off the stairs it earns its place wherever LVT meets a vertical face: along the base of a wall in place of a scotia, around a plinth or a kitchen island, and at the foot of an upstand in a wet-prone room where you would rather not leave an open plank 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\u003eInternal (inner) corner profile, anodised aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eManufacturer reference\u003c\/td\u003e\n\u003ctd\u003eC31 (supplier MPN)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUpright leg\u003c\/td\u003e\n\u003ctd\u003e28 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBase leg\u003c\/td\u003e\n\u003ctd\u003e28 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlooring recess\u003c\/td\u003e\n\u003ctd\u003e5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSuits\u003c\/td\u003e\n\u003ctd\u003e5 mm LVT and click vinyl; supplier states it is suitable for both dry-back and click flooring\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLengths\u003c\/td\u003e\n\u003ctd\u003e900 mm and 2700 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFinishes\u003c\/td\u003e\n\u003ctd\u003eSilver, Gold, Champagne, Black — anodised; supplier states a matt, low-gloss finish\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eEdge type\u003c\/td\u003e\n\u003ctd\u003eStraight edge (supplier stated)\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; supplier states each length is supplied with plugs and screws\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eInternal use, commercial and residential (supplier 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  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eChoosing the right option\u003c\/h2\u003e\n\u003cp\u003eFirst check that you want the inner corner and not the outer. Hold the profile against the junction: this one wraps an \u003cem\u003einternal\u003c\/em\u003e angle, where the floor turns up into a vertical face and the two surfaces close towards each other. If your floor instead turns down over an edge — the front of a step, the lip of a landing — you need the outer-edge profile, which is a different section.\u003c\/p\u003e\n\u003cp\u003eOn length, 900 mm suits a single tread-to-riser junction or a short return, and most buyers ordering for a flight take one per step. The 2700 mm length works out better per metre and is the right choice for a continuous wall or landing run, since fewer joints means fewer places for the line to break. Measure the run, then allow a little for the cut.\u003c\/p\u003e\n\u003cp\u003eFinish is a straightforward decision between matching the floor and matching the ironmongery. Silver is the safe default against grey and light oak decors; black reads deliberate against dark planks and white walls; gold and champagne suit warmer schemes and brassware.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation, use and care\u003c\/h2\u003e\n\u003cp\u003eFit the profile before the final run of flooring goes down. Set it into the angle, mark and drill the substrate, and fix through the pre-drilled countersunk holes using the plugs and screws supplied, checking the line as you go. Then slide the plank edge into the 5 mm recess. Cut to length with a fine-tooth hacksaw or a mitre saw fitted with a non-ferrous blade, and take the burr off the cut end with a file before you offer it up. In service it needs nothing beyond normal floor cleaning: wipe with a damp cloth and avoid abrasive creams and solvent-based cleaners, which will dull an anodised surface.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes this go on the front edge of the step?\u003c\/summary\u003e\u003cp\u003eNo, and this is the one thing worth getting right before you order. The trim that wraps the front edge of a tread is a tread nosing, and it is a different section. This profile does the opposite corner: the internal angle at the back of the tread where it turns up into the riser, or at the foot of the flight where the floor meets the first riser. Most stair jobs need both, and they are not interchangeable.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat thickness of flooring does it take?\u003c\/summary\u003e\u003cp\u003eThe recess is 5 mm, so it is made for 5 mm LVT and click vinyl. The supplier states it suits both dry-back and click flooring. A thinner floor will sit loose in the recess and a thicker one will not enter it, so check your plank thickness before ordering.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use it as skirting along a wall?\u003c\/summary\u003e\u003cp\u003eYes. It is the same junction — flooring meeting a vertical face — and the supplier lists hallways, landings and kitchens alongside stairs. Fitted along a wall it gives a low, flush metal line instead of a timber scotia, and because the plank edge tucks into the recess there is no open gap at the floor to collect dirt. Bear in mind it is only 28 mm tall, so it is a floor trim rather than a replacement for a full-height skirting board.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eAre the fixings included?\u003c\/summary\u003e\u003cp\u003eYes.

Both lengths cut cleanly with a fine-tooth hacksaw or a mitre saw fitted with a non-ferrous blade.

It is an edge-finishing trim rather than a trafficked anti-slip product.
