Used in urban areas with higher density, as they have the same resistance in any direction. The mold consists of a set of sides, bed, and core. Circular posts have a hollow section to reduce weight. To create this hollow section, a core is used that runs through the entire length of the mold.
Circular Model Type R
With a nominal load ranging from 100 to 5000 daN and variable length. They have a conicity of 20mm per meter, as shown in the table:
