Abstract (en)

[origin: EP0921250A2] At least one longitudinal bar (10,12) has two at least essentially flat side walls (18,19,20,21), whereby the height of these side walls is greater than the width (23,24,25,26) of the longitudinal bars. The longitudinal bars (10,12) are surface-rolled round bars. The starting cross-section of the round bars is smaller or not more than preferably approximately 5 per cent larger than the cross-section of the round bars used for the cross bars ((14,16). The diameter of the cross bars (14,16) is approximately 4.2 mm. A round cross-section starting material for the longitudinal bars (10,12) is subjected to cold forming in a cross-section of approximately 3.9 x 4.9 mm with slight rounded narrow sides (22,23,24,25) and even broad sides (18,19,20,21).
