A masterpiece of precision and complexity

Both of which are strong qualities of Dallan and showcase our expertise in the thin material roll forming industry.

This machine includes a Dallan T5 machine with more than 600 rollers and the obtained profiles are construction modules to be filled with concrete.

The accuracy of the profiles is the key

The profiles have to:

  • Close tightly
  • Match perfectly
  • They also need to be perfectly straightened as they can be up to 9 meters long

Once the profiles are produced, they are stacked on special conveyors to be picked by the following automation.

Our philosophy

The Dallan machines are to be used also by non-expert personnel, and we introduced new and effective methods to straighten the profiles via the control panel.
