Abstract: A scaffolding coupler intended for fixed attachment to the ends of a ledger of a scaffolding system. The scaffolding coupler comprises a foot and a hook which is integrally connected with the foot. The hook has a radial inside contour which is substantially circular segmental. The scaffolding coupler has at least one supporting surface which is formed by the foot and the hook and which, with the scaffolding coupler connected to a standard, rests on a supporting projection of the respective standard. The scaffolding coupler further comprises a pin which is slideably connected to the hook. The pin is configured as a bent pin, having a substantially circular segmental inside contour, which, in use, abuts directly against a pipe wall of a standard to be coupled to the first ledger or a ledger. The bent pin has a substantially circular segmental outside contour which abuts against the substantially circular segmental inside contour of the hook.

Abstract: In a method for manufacturing an element (8) of a modular scaffolding system, an at least partly galvanized pipe part (10) having a first end (12) and a second end is provided, together with an at least partly galvanized first connection head (40) which is designed to be connected to the first end (12) of the pipe part (10). A weld (24), which connects the first end (12) of the pipe part (10) to the first connection head (40), has an internal weld surface (24b) and an external weld surface (24a). The internal weld surface is proximal to the pipe part (10) and/or the connection head (40), and the external weld surface is proximal to an outside environment (60) of the pipe part (10) and the connecting head (40). A protective layer covers the external weld surface, such that it is screened off from the outside environment (60).

Abstract: A method for manufacturing an element (8) of a modular scaffolding system, comprising: providing an at least partly galvanized pipe part (10) having a first end (12) and a second end; providing an at least partly galvanized first connection head (40) which is designed to be connected to the first end (12) of the pipe part (10); forming, through welding, a weld (24) which connects the first end (12) of the pipe part (10) to the first connection head (40), the weld (24) comprising an internal weld surface (24b) and an external weld surface (24a), which internal weld surface is proximal to the pipe part (10) and/or the connection head (40), and which external weld surface is proximal to an outside environment (60) of the pipe part (10) and the connecting head (40).; and covering the external weld surface with a protective layer, such that the external weld surface is screened off from the outside environment (60).
