Upsetting technology is a parallel-thread mechanical splicing system designed for the connection of 16mm to 40mm reinforcing bars. This system is a patented cold upsetting and Metric thread Cutting process which can grantee an ultimate tensile strength of the bar connecting and make the bar break.
It is designed and manufactured in compliance with China standard of JGJ107-2010, UK standard of BS8110, USA standard of ACI318, VN standard of TCVN8163 and other international standards.
