A 3-Steps Process
Step 1 – Cutting
The end of the reinforcing bar is sawn square.
Step 2 – Cold Forging
The sawn end of the rebar is then enlarged by a patented cold forging process. The core diameter of the bar is increased to a pre-determined diameter.
Step 3 – Threading
Finally, the enlarged end of the rebar is threaded to the required length.
To connect cages that haven’t been prefabricated together or sets of bars that can’t be brought butt to butt, Bartec Caging Splice is your solution. Both bars are threaded with a standard Bartec thread, then the free rotating elements of the Caging Splice will restore thread continuity and make the connection.
When there is a need to splice bars of different sizes, it is allowable in most cases to reduce the size of the larger bar and to use a standard coupler.
However the Bartec® system also offers special transition couplers that conveniently avoid the difficult task of planning in advance the need of transitions.
Also called “End Anchors”, they are a convenient alternative to hooked bars to provide end anchorages in congested areas. Bartec® standard anchorage heads
are circular and have a net bearing area of 4 times or 9 times the cross-section of the bar.
For composite construction where concrete reinforcement bars must be welded to structural steel, use Bartec® weldable couplers, which are specially made from low carbon steel and which have a large chamfer for bevel welding.
