Abstract (en)
[origin: EP0347476A1] To allow a plank for scaffolding in the form of an elongated hollow metal profile (1) to be subjected to high stresses, it is proposed that a closure profile (17) is pushed into each of the front ends (12, 13), and that the holes (6, 7, 8, 9), serving for fastening to the scaffolding, are formed by flow forming in such a way that the metal of the hollow metal profile (1) and of the closure profile (17) is fused together in the region of the to be formed holes (6, 7, 8, 9) by flow forming into cylindrical bushes (28, 29). <IMAGE>
