Engineering solution
What this equipment is designed to solve
Round air ducts made of galvanized steel, manufactured by spiral winding. Diameters from Ø100 to Ø1250 mm. Corresponds to VSN 353-86, TU 36-736-93.
Advantages of spiral-wound air ducts
- Increased rigidity thanks to spiral seam at low weight
- Low noise level – quieter than rectangular counterparts
- Sealed spiral connection – minimal air loss
- Smooth inner surface – low aerodynamic drag
- Anti-corrosion protection – zinc coating, service life up to 25 years
- Section length up to 6 m (Ø≤500 mm) – fewer connections, quick installation
Material

Frequently Asked Questions
We produce 11 standard sizes – from Ø100 to Ø1250 mm (spiral) and any rectangular section according to the project. Non-standard sizes – according to customer drawings.
Galvanized steel 08ps, thickness 0.5–1.0 mm. For aggressive environments – stainless steel AISI 304/316. The thickness is selected according to the operating conditions.
The period depends on the execution, configuration, batch size and current production load. After checking the technical specifications, we fix it in the commercial proposal and contract.
The standard length is 1.25 m. On request, we produce sections of 2.5 m and 3.0 m to reduce the number of connections on site.
