The NSL16 Aluminium Stair Nosing with Tredsafe® Insert is engineered for demanding commercial and industrial environments where enhanced slip resistance is essential. Designed in a durable 3mm gauge aluminium, this profile provides robust edge protection while delivering superior underfoot safety.

Suitable for installation with vinyl, linoleum and medium carpets or similar floor coverings, the NSL16 ensures a secure, professional finish across a wide range of stair constructions. The profile is manufactured with DDA and building regulations accounted for and is designed to meet the recommendations of BS8300:2009+A1:2010, making it ideal for public buildings, schools, hospitals and retail environments.

The integrated external grade Tredsafe® insert is manufactured from a specialist blend of P.V.C., silica quartz and polymeric plasticiser, forming a homogeneous, hard-wearing anti-slip surface suitable for both wet and dry conditions. The distinctive three-dimensional pyramid pattern provides excellent slip resistance, helping to significantly reduce the risk of slips and falls in high-traffic or moisture-prone areas.

Tredsafe® inserts achieve R11 slip resistance classification (DIN 51130) and offer reliable long-term performance in challenging environments. The insert is also resistant to UV light, oil, grease and common cleaning chemicals, making it suitable for both internal and external applications.

Available in standard lengths of 2.46m, 2.77m and 3.22m, the NSL16 Tredsafe® Stair Nosing combines compliance, durability and industry-leading slip resistance for complete stair safety.
