Round spiral duct 560mm

The round spiral duct 560mm, produced by a modern German production line. The materials are of the highest quality with proven origin. The edge of the duct is cut by steel cutlery, protecting its galvanized surface. This method of cutting does not allow the duct to start early corrosion, because the unburnt zink coating preserves the steel from the oxigen. 

Our technology guarantees excellent airtightness, strength and damage resistance of the duct.
