Frequently Asked Questions

Can this stair nosing be fitted to both concrete and timber stairs?

Yes, the profile can be installed on most solid stair substrates, including concrete and timber. Appropriate fixings and, where required, suitable adhesives should be selected based on the substrate and floor covering.

Which insert colour should I choose for the best visibility?

High-contrast colours such as yellow castellated or polar grey castellated are typically chosen to improve visibility against darker floor finishes and to aid users with reduced vision.

Is this nosing suitable for use on external steps?

This profile is primarily intended for internal use. For external applications, additional consideration should be given to weather exposure, moisture, and cleaning regimes, and a profile specifically rated for outdoor conditions may be more appropriate.
