Abstract: A method of making a metal frame that will be used to make metal panels that will be used to fabricate modular metal buildings. Currently, the metal frames are manufactured through forming processes, however, the steps adopted end up generating greater difficulty in the conformation of the metal sheet, and, consequently, increase in the manufacturing time; as well as, they cannot achieve a higher degree of quality, which reduces the added value of the metal frame and can lead to greater difficulty of assembly, lower productivity and higher labor cost. The ideal method, comprises of modular plates (1) that are formed by galvanized sheet frames (2), which are manufactured by the method with 22 forming steps through a roll forming machine (7) with profiling rolls (9) with specific frames (10), and each step has a roll (9) and a set of support rollers (12) for each forming step.
