The concrete poles used with this fencing system are made of reinforced concrete (centrifuged or vibrated) with minimum standards C30/37 and DIN 1045-2/A1. The concrete poles have the shape of a truncated cone or a frustum of pyramid with a circular, hexagonal or of a regular octagon shape cross section. The basic reinforcement of the poles consists of at least 6 rods of 8.00mm diameter (S400KTX) for those of octagonal or hexagonal cross section and 4 rods of 8.00mm diameter (S400KTX) for those of square cross section. Rings or rectangular clips of 4.00mm diameter (S400KTX) are used with a distance of 35cm between them, along the pole for the reinforcement of the cross section.
