It is arranged that a steel structure can be strongly assembled. In order to join two steel products, which form a steel structure or reinforcing members therefor, the junction surfaces of one and/or the other steel product are formed with a slip suppression-processed surface having one or a plurality of crests and grooves in a concentric circle, and the two steel products are clamped by means of connecting members extending through connecting holes in such a manner that the first and second slip suppression-processed surfaces are engaged with each other or are not engaged with each other, whereby the joining proof stress between the junction surfaces is increased. |
