A beam is a long element adapted to transfer a traverse load to pillars. A concrete beam optimally uses the mechanical properties of its material by counteracting prestressing actions through concrete mix and stressing actions through steel. Thanks to the prestressing technique, it is now possible to improve beam strength properties enabling high loads on large spans, limiting the element weight and increasing its fire resistance. On the market, there are beams of several geometry and size used in civil engineering works, industrial buildings and infrastructures.
