Carborundum filled heavy duty stair nosing with a 55 x 55 mm coloured riser and tread surface to help with Building Regulations and British Standards compliance.
MH5 (formally QA1) and MH5R (formally QA2) Heavy Duty Carborundum Stair nosings are designed to help with Building Regulations (Document M & K) and British Standards requirements by providing a high contrast 55 mm riser and 55 mm tread surface with a heavy duty anti-slip finish.
