A local school with able-bodied and wheelchair users has had a new link bridge built with a metal 'checkerplate' surface (the bridge has gentle sloped and level areas). Rain pools on areas of the bridge, freezes in cold weather and is a cause for a number of slips. We have had holes drilled throught the checkerplate to allow rain to drain away and this has reduced but not removed this problem. The original checkerplate finish was also felt to be too slippery, especially when wet and a non-slip paint with a granular finish was applied. The school still says that this does not prevent slips.

My suggestion is to put down some (say) 100mm wide strips of fibreglass non-slip sheet which has very good grip properties, long life expectancy and the alternating bands of fibreglass sheet with raised edges of between 4-6mm would give grip to pedestrians without hampering wheelchair users.

Has anyone got any other suggestions or systems that they've used and found to be suitable in such a situation?

Would expanded metal mesh be suitable?

Take a look at www.expandedmetalcompany.co.uk for examples

Simon - you say "New" - how new is that because this is clearly a design fault and should have been designed out. Are you able to go back to your designer/architect for them to resolve this?

Hi Simon,
I've used 'fibregrid' in areas such as bakeries where it has proved very effective.

It is suitable for use outside and we had it fitted over the existing checkerplate.

http://www.fibregrid.com/products/slipgrip.htm is where its at.

Hope this helps.

Regards
Andy

Self-adhesive products can come unstuck and thin sheets can wear away. Surfaces that are too abrasive so as to allow no horizontal movement of the shoe can also present hazards to pedestrians and alterate surfaces with raised edges can present tripping hazards. I am surprised that a combination of anti-slip applied coating and drainage hasn't given you an adequate surface. Was there no possibility of designing this structure with weather protection and no way to retro-fit this?
