A higher slip resistance rating does not necessarily provide a better solution
It is advisable that designers specify materials with a slip resistance rating suitable for the application. A trip hazard may occur when a grate has a higher slip resistance rating than the surrounding floor surface.
The Standards Australia Handbook SA HB 198: Guide to the Specification and Testing of Slip Resistance of Pedestrian Surfaces, provides the following information:
- Slip resistance classification of new pedestrian surface materials compliant to AS 4586
- Commentary on the National Construction Code (NCC) that references AS 4586 for particular applications
- General guidance for specifying pedestrian safe materials
