Couplers are key connecting parts used in traditional fastener-type scaffolding systems to fix scaffold members, components or structures, that are formed by mechanical biting or structural fastening realiz the vertical crossing or horizontal connection of steel tubes. Its core function is to transfer the load force of the members and achieve flexible structural adjustment.
Couplers, as key parts for connecting and fixing components, play an irreplaceable role in multiple fields covering construction, machinery, and transportation. According to the different production processes and materials, they are mainly divided into two types: forged couplers and stamped couplers. Based on the classification of common functions and structural forms, the product scope of Jenmour Steel® includes right-angle couplers, swivel couplers, sleeve couplers, girder couplers, putlog couplers, joint pin, single couplers, basically covering all types in today's constructional coupler market.
