Lapped splices are not always the most economical solution for connecting rebar in columns and beams. The overlapped rebar represent wasted rebar material and time consuming rebar fixing. The use of mechanical couplers can create material and time savings and simplify the management of rebar fixing and installation.
SteelAsia offers mechanical couplers and rebar threading services.
SteelAsia offers Bartec couplers. The Bartec system involves a cold-forging process to increase its rebar diameter prior to threading. Thread is then mechanically cut unto the enlarged end of the bar. Through this process, there is no reduction the rebar’s cross section area. Couplers can then be physically attached by screwing directly onto the rebar.
