Introduction to the Hy-Ten Coupler – called HT of UK Origin.
The HT Coupler range is for the mechanical connection of deformed steel reinforcing bars complying with BS4449 grades 500B & 500C and ASTM A615 grades 60 & 75.
The HT Coupler is CARES approved to TA1-B and TA1-C (including the performance requirements of EC2 & Sellafield Technical Standards).
The HT Range consists of the HT.S Standard Coupler, HT.P, HT.EP & HT.LT Positional Couplers, HT.C Connecting Coupler and HT.A & HT.EA Mechanical Anchors.
The Standard and Positional HT Couplers can be used not only where the 2 bars are of the same diameter, but also where the 2 bars are of different diameter (i.e. transitional joints).
The HT.S is used where at least 1 bar is rotatable. The HT.P is used where no bar is rotatable but at least 1 bar is moveable.
The HT.EP is used where neither bar is rotatable, at least 1 bar is movable, where length adjustment of the coupler is required.
The HT.LT is used where neither bar is rotatable, at least 1 bar is movable, where an extended length adjustment of the coupler is required.
The HT Coupler heads are produced and threaded in a dedicated production facility using CNC lathes. This results in a high quality product with more accurate & consistent threads than can be achieved through the rebar threading required by other systems.
The high quality threads also mean that a torque wrench is not required for on-site installation.
The HT Coupler heads are welded onto the appropriate rebars using the computer controlled HT Friction Welder. This process is much faster than the threading of rebars required by other systems.
The combination of the friction welding process and the high quality machined threads allows the system to achieve bar break and to have substantial advantages in terms of QUALITY, COST & LEAD TIME
