ABP Scaffolding
Upsetting type rebar coupler is a robust parallel thread mechanical splicing system that enlarges rebar nominal diameters by cold forging prior to thread cutting. After cutting, the thread's minor diameter remains larger than the rebar's nominal diameter, ensuring exceptionally strong connections. This specialized design yields smooth threads for rapid, easy installations and high-efficiency structural connections.

With more than 10 years of expertise in high-grade rebar couplers manufacture, the enterprise operates out of a modern facility spanning over 5,000 square meters. Initially serving the major domestic nuclear power stations and large-scale industrial complexes, the brand expanded globally in 2016. Ongoing research and development led to successful cone-thread structural systems in 2017 and advanced rapid-connect systems in 2018.
Operating under rigorous internal management protocols, the facility processes and exports standard and custom-made connection solutions to the USA, Europe, Australia, and key Asian-Pacific regions. Annual productivity exceeds 5,000,000 units of versatile configurations, ensuring rapid delivery times (often within 5 days for single container requirements) and uncompromised quality controls.
