Non-slip manhole covers
Improved surface adhesion
If you are looking for non-slip manhole covers look no further. The SSC cover’s top surface material has a better slip-resistance value in a wet, dry, or worn state, than any other commercially used material and is comparable with a good highway surface.
Current specifications regarding non-slip manhole covers see Engineers asking for materials with a co-efficient of friction that is 0.50 and Health & Safety institutions consider any material of less than 0.40 as unsuitable for use in public areas.
An SSC non-slip manhole covers have a value of not less than 0.7.
Note the multi direction pattern on C250 and D400 range of products.
A recent motorcycle fatality has been attributed to a ‘slippy’ metal cover. This was measured at less than 0.40 co-efficient of friction, which is the value that Health & Safety regard as hazardous.
