The NSL20 Aluminium Stair Nosing with integrated Tredsafe® anti-slip insert is a commercial-grade profile engineered for long-term safety and performance in high-traffic environments. Featuring a 3mm rakeback gauge, this profile is specifically designed for angled stair risers at approximately 83°, offering a sleek fit on precast and concrete stairs.

Constructed from mill finish aluminium, the NSL20 is built for durability and can be powder-coated or anodised on request to suit your project’s finish requirements. Its Tredsafe® insert, made from a specialist mix of PVC, silica quartz, and polymeric plasticiser, provides exceptional slip resistance via a 3D pyramid-textured surface, even in wet conditions.

Fully compliant with DDA and BS8300:2009+A1:2010, this nosing supports visual contrast and accessibility in accordance with Approved Document M. It is compatible with vinyl, LVT, linoleum, and medium-pile carpets, making it a reliable solution for schools, healthcare environments, transport hubs, and public stairwells.

Supplied pre-drilled through the insert, with colour-matched pips to conceal fixings. Undrilled and channel-only configurations with separately supplied inserts are available upon request. Fixings not included.
