Rectangular ductwork
Rectangular ducts are produced with the help of the two automated production lines "FIRMAC" type ADF and MDF, with integrated flange CGF20 or CGF30.
Our range consists of rectangular ducts and fittings with dimensions respecting EN 1505 standard. The entire range of rectangular products is made of Z 275 galvanized steel sheet, but for greater resistance against corrosion pieces can be made of aluzinc or stainless steel.
At the customer's request rectangular pieces tailor-made pieces can be produced, ensuring the same quality in terms of materials and manufacturing processes. Rectangular ducts can be supplied as semi-finished products in the shape of the letter L, in order to make transportation more efficient.
