The columns are made of reinforced concrete, with square or rectangular cross-sections.
Their height ranges from 2 m to 15 m.
They are generally embedded at the base and transfer the loads from the bearing beams to the foundations.
They can absorb all or part of the lateral loads and take up the loads of travelling cranes.
They can include 1 to 3 corbels.
The bushings or stand-by armatures are positioned using templates.
