We manufacture two types of ventilation ducts: rectangular and circular.
They are made of the following metal sheet types:
- black (metal sheet coated by spraying and powder-coated, hot-dip galvanised);
Rectangular ducts are available in the following versions:
- without insulation (standard),
- insulated on the outside (with mineral wool and galvanised steel casing);
- insulated on the inside (with mineral wool).
Circular ducts are available as:
- spiral pipes;
- welded pipes and profiles;
- connecting profiles and components.
KMW Engineering also offers components constructed in the stay-in-place formwork technology.
