Rectangles 50×11 mm are cut out on both sides at one end of the reamer. On the resulting shaped reamer, stiffeners are made along the edges, stiffeners are bent on both sides along the length of the reamer. On three-roll rollers, a chute is made by rolling. To assemble the gutter with the cut-out side, it is inserted inside the second gutter from the side without cutting-out, silicone sealant is applied to the junction. To increase the rigidity of the assembled gutters, a blind rivet is installed.
