Galvanized Steel Spiral Clamped Air Ducts

– 0.50mm – 1.00mm (inclusive) (110gr or 275gr galvanized sheet) thickness range,

Circular air duct is produced by clamping galvanized steel sheet in special machines. Duct diameters, dimensions of duct fittings, tolerances are produced in accordance with EN 1505 and 1506 and galvanized sheet material EN 10142. All duct parts, elbows and connections are designed in the most appropriate way in terms of sound level and aerodynamics. 100 mm with spiral pipes shaped with precise tolerances in fully automatic machines. with 1,600 mm. diameter range is produced. Maximum sealing is provided at high pressures. Fittings channel parts are produced in CNC plasma cutting machine according to the desired dimensions.
