Abstract

PROBLEM TO BE SOLVED: To dispense with a welding operation or a riveting operation for joining a longitudinal frame member to an expanded metal, to facilitate manufacture and, moreover, to attain inexpensiveness. SOLUTION: A scaffold material 1 is made of an expanded metal and hollow longitudinal frame parts 2A each extending in the length direction over the full length and having a rectangular cross section are formed integrally in the opposite edge parts thereof. In the central part in the width direction of an expanded part 3 between the longitudinal frame parts 2A on the opposite sides, a hollow intermediate frame part 2B extending in the length direction over the full length and having a rectangular cross section is formed integrally with the material. Non-slip members 26 are fitted to the lower sides of the opposite-side longitudinal frame parts 2A and the intermediate frame part respectively. An upper connective part 26a of each non-slip member 26 is fitted in an inward expanded groove 25. A lower non-slip part 26b thereof is positioned below bottom walls 24 of the opposite-side longitudinal frame parts 2A and the intermediate frame part 2B.
