Galvanised steel - Import export

Based on the customer technical data ad requirements, we offer complete manufacturing solutions. Aluminum anodizing is also available

Round spiral ducts are available in diameters from 80 mm to 1600 mm. The ducts are available as made of 0.4 mm to 1.8 mm thick metal sheet; the ducts in diameters of DN 160 mm or greater are also available with corrugation for improved stiffness and vacuum strength. The corrugations are available as a standard feature for diameters of DN 250 mm to DN 1600 mm. All spiral ducts made from galvanized steel sheet, stainless steel sheet or aluminium sheet meet requirements of air tightness class D according to EN 12237.

longitudinal welding with overlap pipe for transporting air and dust. TRANSQuick system is made of galvanised steel sheet, 0.7 and 0.9 mm in thickness. Depending on the wall thickness there are available various lengths 0.7 mm thickness L=500 / 1000 / 1480 mm. 0.9 mm thickness L=500 / 1000 mm

The fire dampers are manufactured in the following nominal sizes DN100, DN125, DN160, DN200. The fire dampers are equipped with a thermal fuse mechanism ensuring the damper switch to the safe position in case of reaching an ambient temperature equal to or higher than 72°C. The fire dampers allow using limit switches signalling closed position of the damper blade (1 limit switch) or blades (in case of using 2 limit switches). The casing is made from galvanised steel sheet; the fire damper blade is made from a silicate cement board.
