BT Stainless Steel Couplers
The Ancon range of couplers are predominantly designed for the joining of carbon steel bars, however when stainless steel reinforcement is being used the Ancon BT Stainless Steel coupler is ideal.
These couplers are available in either grade 316 or Duplex stainless steel to match the grades of rebar available in the market. They are suitable for projects of any size where the strength of the connection is required to match or exceed that of parent bars, including large scale, high volume coupler applications.
The end of each bar to be joined is cut square and enlarged by cold forging. This increases the core diameter of the bar to ensure that the joint is stronger than the bar. Parallel metric threads are formed onto the bar ends.
There are currently no local standards covering stainless steel reinforcement. Stainless steel reinforcement is generally imported from mills in Europe. Available bar sizes are limited to European standards.

BT Stainless Steel Type A
The Type A connection utilises an internally threaded coupler to join two cold-forged and threaded bar ends together. Each bar end is threaded to half the length of the coupler. Type A connections are used where the continuation bar can be rotated.
BT Stainless Steel Type B
The Type B connection utilises the same coupler as for the Type A, the difference being one bar end is threaded for the full coupler length. Type B connections are used where the continuation bar can be rotated for no more than one revolution.
BT Stainless Steel Type C
The Type C connection utilises the same coupler as for the Type A, together with locknuts and longer threads to the bar ends. Type C connections are used where the continuation bar cannot be rotated.
