Directly Forming to Square and Rectangular Tube Mill


The square or rectangular shaping is formed out before the tube welding, with important advantages in terms of power and material cost reduction.

Computerized Roll Positioning for quick adjustment of roll setting without any roll change (in forming – welding – sizing – straightening) for any size included into the mill size range.


Extreme reduction of mill set up time.

Elimination of all cost for roll sets.

Increase of productivity and reduction of stock and relative costs.

Reduction of manpower due to the complete automatization of the mill operation and adjustments.

Minimal and easy maintenance.

Display with automatic illustration of tube section for each production step.

Easy use of software for setting up of any production parameter, including tube angle radius.
