Props are auxiliary elements that support a horizontal formwork system and position it at the required height in each case.

As load-bearing elements, they are responsible for transmitting to the ground the loads they receive when the structure is concreted and act as support until it is put into service, once it has reached the necessary strength to absorb the necessary stresses.

They are height-adjustable and telescopic. They are generally comprised of two hollow cylindrical bodies which facilitate regulation, one inside the other (body and shaft). In some cases, as a complement, they may have a locking system to prevent the shaft from separating from the body, as well as an unloading system to facilitate removal and disassembly.
