Rectangular Duct
The rectangular duct offers maximum reliability and it improves conventional installation systems significantly.
Its special configuration offers far stronger properties resulting in a more agile, resistant and aesthetic duct.
We can manufacture the products using Metu extensions (Metu System) and we also have two different types of rollforming machines (WAMMES and FIRMAC) to make ducts with a comprehensive profile, depending on the needs of our client.
As for transverse joints, we have machines for making Pittsburg type joints as well as Snaplock Seam
The reports of the tests which our rectangular duct has undergone in our facilities have determined a class D airtightness.
Complying with the UNE-EN 1507:2007 standard for building ventilation.
This confirms and certifies the high quality of its manufacture.
