The truck and train tanks are built by Bending steel or aluminum sheets with a width between 6 meters and 12 meters depending on the type of application, which allows the bending of a single piece in order to avoid circumferential welding. It is possible obtain the greatest savings in the welding phase, where having the possibility of using wider sheets, a saving of 40% can be obtained. Furthermore, the possibility of using longer sheets avoids the problem of joining and verifying the perpendicularity of the different sections that you would have with a less wide machine. Sertom PB Plate rolling Machines prove to be the best solution for the construction of truck and train tanks. Thanks to their structure and precision, they are highly performing and precise machines.
