Diamond plate/checker plate is used widely externally for mezzanine levels, steps and walkways etc but when wet or worn it becomes very slippery. I think i'm right in saying this style of floor covering is designed for outdoor use but in my particular situation is located on some steps and walkways that when wet become a slip hazard which defies the reason for having the diamond plate applied.
Yes I can have the plate removed on the steps, various tread/grip products applied etc but I'm only talking about a few steps.
Any thoughts please?

The HSE labs in Buxton did some work with pendulum testing on this material a few years ago. Conclusion (most) should be considered high slip risk when wet. The problem as I remember it is that unless the tread of your shoes "interlock" with the with pattern you are effectively walking on a very small surface area which when wet offers no slip resistance. If you search the HSE labs data base you should be able to find the slip tests results. Clearly some patterns are better than others and without seeing the material you are using its difficult to be sure.
Have been advised by HSE inspectors to get rid of this material where ever possible or treat it as you state - tread grips etc definitely not considered suitable for outdoor use or where its going to get wet.

We use a plastic type grating and the employees are happy and so are we as we do not have any slips, we had previously had the metal type grating but this also becomes slippy in the wet and icy conditions.

Checkerplate is certainly not great at preventing/minimising slips, especially when wet/contaminated. You may find the following link of interest if you are looking for alternatives or further information......

If you're only talking about a 'few steps'; why not invest in something like this:

Obvious other types/ suppliers are available. :)
Probably a far more pragmatic solution than either doing nothing or replacing the steps. You'll just need to carry out regular inspections to ensure the tape is still in good condition.

Some years ago I attended the HSE travelling "workshop" on slips and trips. I always remember the strongly made point that chequerplate/checkerplate is NOT an anti-slip surface.
Its main use is as a tactile surface - despite its common appearance in places where good slip resistance is needed. I think the comment was made that when wet steel chequerplate is about as safe/dangerous as plain steel!
