Galvanized helical ductwork is the most common solution for ventilation, smoke extraction, air conditioning, and heating systems. It allows for the quick, safe, and airtight construction of complete ventilation, extraction, and supply air networks. Manufactured from high-quality galvanized steel, it offers high mechanical strength and excellent corrosion protection.
Available from stock in lengths up to 3 m and diameters from 100 to 710 mm.
It is the most suitable ducting for countless ventilation applications.
Our standard galvanized steel line covers a wide range of diameters (from 80 mm up to 1,500 mm) and sheet thicknesses from 0.5 to 1.25 mm, manufactured with light reinforcement for diameters over 300 mm.
The standard length of the circular spiral duct is 3 meters, with custom lengths available on request.
The sheet thicknesses used comply with the UNE100-102-88 standard.
Certified according to the UNE EN 12237 tightness standard - Class C and UNE EN 12101-7 standard according to CTE.
