We manufacture two types of ventilation ducts: rectangular and circular.
They are made of the following metal sheet types:

• galvanised;
• acid-proof;
• black (metal sheet coated by spraying and powder-coated, hot-dip galvanised);
• aluminium. 

 

 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.
