It is made for steps that get wet, dirty or gritted, where a smooth PVC insert would be the wrong choice.\u003c\/p\u003e\n\u003cp\u003eThe profile is aluminium with a 3.5mm gauge for vinyl, LVT, wood and other hard flooring. Choose from three insert colours and five finishes, in three stock lengths.\u003c\/p\u003e\n\u003ch2\u003eWhy this profile works\u003c\/h2\u003e\n\u003ch3\u003eGrit, not plastic\u003c\/h3\u003e\n\u003cp\u003eThe back of the tread leg tapers down onto the floor, so there is no upstand to catch a toe or a mop where the nosing meets the covering. The grit face keeps working when the surface is wet, which is exactly when a step edge matters. When the inserts eventually polish down under heavy traffic, they are replaced on their own and the aluminium stays where it is.\u003c\/p\u003e\n\u003ch3\u003eA 3.5mm gauge sets the floors it suits\u003c\/h3\u003e\n\u003cp\u003eThe gauge is the depth your floorcovering meets behind the nosing. At 3.5mm it lines up with vinyl, LVT, wood and other hard flooring, so the covering finishes flush with the back of the profile and nothing catches underfoot.\u003c\/p\u003e\n\u003ch3\u003eA clear edge on a working stair\u003c\/h3\u003e\n\u003cp\u003eWith 70mm on the tread and 32mm on the riser, the nosing marks the step edge clearly from above and from the approach.

The step must be sound, clean and dry. Fix by screwing through the tread leg with fixings suited to the substrate, bedding the profile on a suitable exterior-grade adhesive so water cannot track underneath. Lay the floorcovering up to the back of the profile, then press the inserts fully home.

That texture keeps its grip when the step is wet, which is why it is specified on covered entrances, fire escapes and service steps.

Brimstone (safety yellow) gives the strongest warning and suits service and plant areas. Coal (black) is the discreet choice on grey concrete. Everest (light grey) suits dark stone and asphalt.
