A set of reinforcing bar couplers that are suitable for various project sizes.

Each end of the rebar to be joined is cut square and enlarged using a cold forge process. A thread is then formed on the enlarged bar end using a thread rolling machine. The thread is such that the cross sectional area of the bar ends are not reduced ensuring the strength of the connection matches or exceeds that of the parent bars.

Features and benefits:

Bartec Plus Type A utilizes an internally threaded coupler to join two cold-forged and thread-rolled bar ends together. Each bar end is threaded to half the length of the coupler. Used where the continuation bar can be rotated.
Bartec Plus Type B utilizes the same coupler as for the Type A, except one bar end is threaded for the full coupler length. Used where the continuation bar can be rotated for no more than one revolution.
Bartec Plus Type C utilizes the same coupler as for the Type A, together with locknuts and longer threads to the bar ends. Used where the continuation bar cannot be rotated.
Bartec Plus Type A standard couplers in the size range 16–32 mm and Type C positional couplers in the size range 16–40 mm are covered by UK CARES Technical Approval TA1-A 5050.
Evaluated for use as per TA1-B: Eurocode 2 and BS 8110 for static applications in tension only with BS 4449 grade B500C reinforcement.
