Our bolt down anti slip plates are fabricated from 0.06” thick weatherproof aluminium they have rounded corners and six countersunk holes. The abrasive top coating has a coefficient of friction in excess of minimum requirements.  Our anti slip plates are available with either a black coarse non slip coating or a black/yellow hazard warning non slip coating.  For orders over a certain size we can offer other colors and sizes. The plates are great for fixing onto a previously unsuitable surface, e.g. sodden timber, ribbed decking etc. Each plate is 4.5”x25”.
