The characteristics:

CHO is a totally hydraulic machine, with three or four rolls with numerical control, which has special shaped rolls, allowing to bend corrugated sheets.

The bending can be of constant radius, in case of versions with three rolls, or variable radius, in case of four rolls bending machines with numerical control.

The corrugated sheets thus obtained are used in the construction of roofs of sheds, coatings, pipes, tunnels, underground passages.
