Wellmade Joint Pin Coupler
As a leading scaffolding joint pin coupler manufacturer in China, Wellmade produces both drop-forged type and pressed steel type joint pin couplers. Both of them are used in the scaffold tube clamp system.
As an ISO 9001 & CE certified scaffold factory, all of our scaffolding joint pin coupler products are tested qualified before delivery. All of the scaffolding joint pin couplers are tested according to the international standards of BS1139, EN74, JIS 8951 etc.
Wellmade joint pin couplers are used to fix the scaffolding pipes from the internal side. While in the opposite, scaffold sleeve couplers are scaffold fittings to fix the scaffolding pipes from outside. That is why we called sleeve couplers joint boxes too.
For anti-corrosion purposes, there are E-galvanized (cold galvanized or zinc-plated) joint pins and hot-dip galvanized joint pin couplers for your choosing. Hot-dip galvanized joint pin couplers are used popular on offshore and onshore projects. While you can find both white and yellow colours for the zinc plated joint pin couplers.

Among all types of scaffolding joint pin couplers, bone joints are Japanese standard, while the joint pin for rivet pipes are Korean standard.
For the British standard scaffolding joint pin couplers, you can find drop forged and pressed types. In manufacturing, the drop-forged joint pin couplers are forged from round bars after heating. While the pressed steel type British standard point pin couplers are made from special steel plates.
Joint Pin Coupler for Scaffolding Pipes
British standard joint pin couplers are used for O.D 48.3mm scaffolding pipes. You can connect between type 3 and type 4 scaffolding pipes in the construction.
Japanese standard bone joint pins are the same as Korean standard joint pin couplers. They are used to connect O.D 48.6mm scaffolding pipes.
