CUSTOM MANUFACTURING

CUSTOM
MANUFACTURING

Welded ducts, ventilation towers, fittings and housings in steel, stainless steel and aluminium – to drawing, sample or specification.

WHAT WE
DELIVER

When standard products do not fit, we manufacture. Intelmann GmbH produces welded ventilation towers, ducts, fittings, weather louvres and housings in steel, stainless steel V2A / V4A and aluminium – to your drawing, sample or technical specification.

A particular focus is on ventilation towers: freestanding outdoor installations with louvre hood, standpipe and optional protective grille – welded or flanged, painted, powder-coated, in V2A / V4A or Corten steel. Whether single piece or series, building or ship.

Our custom fabrications are used wherever standard dimensions are not sufficient: high-temperature systems up to 400 °C, seawater-resistant offshore components, custom-made built-in parts for ships and buildings.
