Sheet iron

For more than 25 years we have been specialised in ventilation technology. We present you below our metal ducts - round or rectangular.

These ducts can be manufactured in :

  • galvanised iron
  • aluminium
  • inox
  • synthetic material.


Ducts can be manufactured in practically all dimensions. Standard execution with assembly frames of 20-30 mm, including perforated fastening corners allowing assembling through bolts and nuts. We use a peripheric watertightness joint between two assembly sections in order to obtain a perfect watertightness.

We can also manufcture special pieces such as :

  • horizontal/vertical deviations, or even in both directions
  • round or rectangular ducts
  • anti-vibration and flexible cuffs.


Round ducts

These are sheet iron spiraled ducts in standard dimensions. These ducts are generally fastened with self-drilling screws. You can choose between ducts with our without watertightness joints. There is also a large choice of connecting pieces such as T´s, elbows with an angle between 15 and 90°, reductions, ...

The ducts can be supplied on request in inox, galvanised iron or aluminium. Ducts can also be supplied with smooth inner surfaces, particularly suited for the transport of wood chips, dusty air or abrasives.

Our company respects existing standards.
