Avatar SMC Performance index

Anti slip pattern

Avatar  cover of composite access covers achieved a market leading Skid Resistance Value of 89

The table below has been developed from data collected by County

Surveyors Society and illustrates the acceptabable parameters when tested using the TRRL Pendulum Test in general accordance with BS667:part 1:1986

This test provides a slip resistance value(SRV) for each surface tested The higher value the greater slip resistance.
