Rocklight® is a 3-layer polypropylene composite made up of dimpled sheet sandwiched between two smooth sheets in a proprietary manufacturing process.

The key feature within the panel is its specially designed dimple geometry. The two-sided dimple pattern has only half the dimple height of conventional texturing, ensuring outstanding compressive strength as well as minimum thickness variation on the dimple crowns. Constant wall thickness improves the quality of the welded bond with the outer sheets, therefore further enhancing rigidity. The symmetric dimple structure creates a continuous air gap providing feather-light weight and excellent surface flatness.

Rocklight® plastic panels provide users a unique package of benefits: outstanding strength under tensile, flexural and compressive strength in all directions including edges and sides along with ultra light weight.
