Polystone® CubX® – innovative construction sheet for chemical tank and plant construction

With Polystone® CubX®, Röchling offers a high-performance tank construction sheet for chemical tank and plant construction. The material has been specifically developed for the construction of rectangular tanks and stands out due to its innovative internal cube structure.

This unique structure provides very high longitudinal and transverse stiffness while maintaining low weight. Depending on the application, steel reinforcements in tank construction can be significantly reduced or even completely eliminated. This reduces manufacturing effort, simplifies design and accelerates production.

Polystone® CubX® also features excellent chemical resistance, making it suitable for long-term use in demanding industrial applications. The air trapped within the sheet structure additionally ensures good thermal insulation.
