A cost-effective substitute for ceramic treads is this Slimline Aluminium Tile-In Nosing. 

The tread has an insert made of PVC material with improved slip resistance.

Although it is mostly used with ceramic tile, there are other surfaces you can use it on. 

This is compliant with DDA Guidelines and Building regulations, also available with the Aluminator option (ATS)
