Abstract

In this paper, the mechanical properties of thin walled, high-induction-frequency welded, cold formed circular hollow sections (CFCHS) suitable for crane and scaffolding construction obtained by experimental results are presented. The effect of different kinds of galvanization (batch galvanization and stripgalvanization) is investigated. The CFCHS for the scaffolding tubes possess a nominal diameter of 48.3 mm and their thicknesses range from 1.8 to 3.0 mm with steel grade classification by the manufacturer of S355, S550, S600, S700 and S960. Tests on the whole tube and on strips, both from the welding seam and on the opposite of the welding seam are performed. For the crane construction tubes with a nominal diameter of 90 mm, experiments on tensile-strips are conducted. Thus, it is possible to quantify the differences of mechanical properties such as Rp, 0.2, Rm and the elongation at failure, depending on the type of galvanization and the testing method.
