Improvement to the metallic structure for manufacturing electrical panels / cabinets, enclosing a structure of metallic cross sections (5), with the means for supporting the parts making up the external walls from folded sheets, as well as constituting the means for supporting and mounting the doors with its respective hinges, the upper (6) and lower enclosure with the base (7) and other electrical and electronic inside of the cabinet components.The said structure (5) can be presented semi-assembled, where four of its uprights or four of its cross sections (P1) are completely free whilst all the other cross sections are rigidly integrated into two equal rectangular frames (8) which form the two opposite sides of the said structure (5) and therefore at the corner point of the junction of each rectangular frame (8) there is a complementary device (9) cooperating for the interlinking at 90o between two adjacent cross sections (P2) and (P3) of each frame (8), as also this selfsame device presents the means so that the extremities of the other cross sections (P1) may be coupled between the corners of the rectangular frames (8), thus forming the structure (5).
