Our circular ducts are manufactured from galvanized steel or stainless steel sheets, available in thicknesses from 0.5 mm to 1.5 mm. Diameters range from Ø80 mm to Ø1250 mm. The ducts are continuously welded to ensure Class C airtightness according to EN 1507 / EN 12237. Smooth internal surfaces minimize pressure loss and noise.
Accessories include elbows, reducers, dampers, flanges, and access doors, all compatible with standard HVAC systems. Custom sizes and materials are available upon request.
