This model that specially design for inline hockey and roller skating. Its surface is flat, very suitable for the roller skates. Also the surface is made thicker than normal products, in order to make the tile more robust and stronger. That's also the reason why its tile weight reaches 240 g/tile. supporting legs provide a steady and safe court surface for players. And it doesn't need rubber rolls as sub-base, could be installed on the sub-base directly. This model receives a really good feedback from the roller skating players.
