BS Pressed Swivel Coupler for Scaffolding Fittings

Short Description:

British Standard scaffolding couplers and fittings are manufactured to BS1139 and EN74 specifications, forming a core component of tube-and-coupler scaffolding systems. Historically, steel pipes paired with couplers dominated construction sites worldwide. Even today, this traditional solution remains widely preferred by many contractors for its reliability and simplicity. Within the BS product range, couplers fall into two distinct categories based on production method: pressed steel type and drop-forged type, each serving similar connection functions but with different performance characteristics.
