In the civil construction sector; this machine produces ducts which are purposely leaving a gap beneath the concrete layer. Because of the corrugates on the duct it creates a resistance by preveting a crush. Due to flexibility of the duct; it does not require an extra elbow equipment.
In order to gather flexible ducts, the length is extended by screwing an upper diameter duct onto the other, thus using it as different fitting parts. Duct cutting procedure is conducted by plasma cutting system. Thus compared to saw functioning machines it is obtaines a stainless product.
