Carborundum is the hardest of the common anti-slip infills: it does not burnish 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 walked on in wet boots.\u003c\/p\u003e\n\u003cp\u003e55mm is the widest band in the range. It is the specification for deep goings on heavily used public stairs, and for landings and ramp thresholds where the grip needs to cover the whole step-off zone rather than a single line.\u003c\/p\u003e\n\n\u003ch3\u003eWhy cut to size\u003c\/h3\u003e\n\u003cp\u003eCutting carborundum on site is slow and unpleasant: the grit destroys a fine-toothed blade and the dust is abrasive, and a 55mm section is heavy going with a hand tool. Cutting in a workshop keeps the ends square and the grit intact right to the end of the strip, so it beds cleanly instead of rocking on a burr.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInsert width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e55 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAnti-slip infill\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCarborundum (aluminium oxide grit in resin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCut length range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250 mm to 2000 mm, tolerance +\/- 5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFixing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBedded in adhesive into a routed groove, or screw fixed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eInternal or external\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufactured\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUnited Kingdom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch3\u003eMeasuring and fixing\u003c\/h3\u003e\n\u003cp\u003eMeasure 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 band back at least 15mm from the front arris so the nose edge stays intact, and check the tread thickness and any reinforcement before routing a groove this wide. The substrate must be clean, dry and free of laitance; bed in an 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.\u003c\/p\u003e\n\n\u003ch3\u003eOrdering and delivery\u003c\/h3\u003e\n\u003cp\u003eCut lengths are made to order; allow additional working days over a stock length and we will confirm a dispatch date.
