Coarse Anti-Slip Grip Tape has, like the name suggests, a coarser grit on its surface than that of standard.
The grit is aluminium oxide; but the difference is the grit granules are larger with deeper valleys and higher peaks. A deep anti-slip coating helps to prevent clogging with dirt, dust, ice etc. A deeper grit provides great durability.
Coarse Safety-Grip is BS 7976:2 pendulum tested with results available on the tech specs tab.
Due to the abrasive levels that Coarse Anti-Slip Grip Tape possesses, it is more suitable for areas exposed to constant coverage of dirt or water. Industrial or construction sites do suffer from exposure to dirt, amongst other things. The deep recesses on the surface of coarse grip tape prevent it from becoming clogged within reason, allowing it to provide adequate slip protection in demanding environments.
