COBAGrip anti-slip GRP stair tread covers, full step coverage COBAGrip stair tread covers fit over an entire step, wrapping onto the riser edge to give full anti-slip coverage rather than just a nosing strip. Moulded from GRP with a silicon carbide grit surface, they are tested to DIN 51130 - R13 and BS 7976-2, and pair with COBAGrip floor sheets for a matching anti-slip surface across steps and landings. Key features Full tread coverage - covers the whole step and overlaps onto the riser, unlike nosing-only covers. Slip tested - DIN 51130 - R13 and BS 7976-2, rated low slip potential. Fire tested - DIN 13501 Bfl-s1 (2018), EN ISO 11925-2:2020 and EN ISO 9239-1:2010 (both 2021). Wide temperature range - performs from -50°C to +90°C. Contrast colourways - black and white or black and yellow, giving the tonal contrast used to meet Equality Act accessibility requirements for step nosings. Bond or screw fixing - fits directly onto existing steps. Where it is used Entrances, fire escapes and access stairwells Car parks and public buildings Schools, universities, warehouses and hospitals Outdoor and exposed stairways Sizes and colours Each cover is 345mm deep with a 55mm nosing edge and 5mm overall thickness. The black and yellow colourway is available in 0.75m, 1m, 1.5m, 2m and 3m lengths; black and white runs from 1m to 3m. Use alongside COBAGrip floor sheets for a matching anti-slip surface, and our GRP fixing glue or screw fixings for installation.
