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.
Q1 and 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.
Manufactured in the UK from aluminium with a coloured PVC riser strip and Carbigrip carborundum anti-slip tread infill, which consists of a resin and abrasive mineral mixture.
QA1 and QA2 can be recessed into a step edge or combined with QA5 – Modular Profile Ramp for a stand-alone Building Regulations compliant nosing. QA1 or QA2 can also be combined with the QA4 tread extender, in order to create a full heavy duty ant-slip stair tread cover.
