According to researchers from the Polytechnic University of Valencia who developed the patent, the beams use recycled plastic as the raw ingredient. Thanks to their polymeric profile, they can be assembled and installed anywhere while maintaining their structural rigidity. And because they contain zero metal, they won’t corrode over time. The crack team was able to minimize the beam’s weight so dramatically by using an alveolar structure, a natural system found in human bones, to seal the deal.
