<p>A method for production of a metal profile (16, 17, 18) for a building frame (1) and a metal profile assembly comprising such metal profiles is described. The method comprises the step of providing a sheet metal (41), feeding the sheet metal (41) in a feeding direction, when the sheet metal (41) is fed in the feeding direction, bending the sheet metal (41) to a bent profile comprising a web (9) and flanges (10, 11) on either side of the web (9), and cutting off a metal profile of the bent profile. The cutting is made so that the metal profile (16, 17, 18) gets a length which is adapted to a predetermined building frame (1) so that the metal profile (16, 17, 18) may be used for the building frame (1) directly without additional cutting of the metal profile (16, 17, 18). The method comprises the step, before the cutting, of arranging fastening holes (14) on predetermined positions on the metal profile (16, 17, 18) so that the metal profile may be attached to other metal profiles (16, 17, 18) in the building frame (1) directly without need of drilling any additional holes in the metal profile (16, 17, 18).</p> |
