<p>The skate-boarding area is made up of modular units which are placed side by side and connected by edges which correspond to those of the adjacent unit. The units are made of polyester glass in laminated form, with the upper surface covered with a coating of gel, and the underneath surface being reinforced. The reinforcements consist of a polyurethane foam core covered with the laminated material. The edges of the units have rims, and are supported on the ground by means of props which are adjustable in height. The top covering can be coloured or have an advertising design.</p> |
