Due to its characteristics, the circular helical duct is the most suitable for countless applications.
Our standard line of galvanized steel covers a wide range of diameters from 80mm up to 1500mm, the thickness goes from 0.5mm to 1,25mm, reinforced for diameters above 300mm.
In stainless steel, we made them with the same characteristics and diameters in 0.5mm thickness. The great diameter series belong to diameters from 1500mm to 2250mm and the thickness is from 1,5mm to 2,5mm.
The standard length of the galvanized duct is between 3 and 5 meters, and tailor-made upon request.
We complement the most demanding requests with a wide range of standard accessories and special pieces, for any type of our ducts whether it is a galvanized, helical, corrugated, auto connected or insulated duct.
The unions between ducts and accessories are realized directly in all cases, not being necessary any special element for the union. The union between ducting sections is done through an accessory union/duct.
The thickness of the steel sheet used comply to the norm UNE 100-102-88.
