The 30mm Premium Rubber Gym Tile has a hard wearing ultra fine granule surface layer and a medium granule base layer. The Premium tiles are more abrasive resistant than standard rubber tiles. Perfect for protecting your subfloor and prolonging the life of your free weights and functional equipment with excellent noise suppression and rebound properties. We recommend using the 30mm Rubber Gym tiles in free weights areas, or any place in your gym where weights will be dropped. These tiles do not require a floor adhesive and lock together with hidden plastic connectors under each tile. This means they are easy to fit and can be easily moved in the future.
