T-headed bars
HRC 100 & 200 Series
HRC 100 Series
HRC 200 Series
HRC 100/200 Series T-Headed bars are manufactured by a friction-forging process, under strict quality control to ensure a zero-slip connection between head and bar that exceeds the actual tensile strength of A706 reinforcement bar.
Head sizes are in accordance with ASTM A 970 (1997-2004) and Caltrans Full Size (9Ab) to transfer the full rebar force into multi-axial stresses in the concrete beneath the head without crushing the concrete or bending the head. Conservatively used when 4Ab heads are required.
For the designer
- Concentrated anchorage of the actual (real) tensile strength of the rebar — in the T-head.
- The full ductility of the rebar is maintained —the very basis for a robust structure.
- Reduces congestion by avoiding anchorage bends and hooks
- Possible to use fewer larger bars
- Excellent confinement effect
- Can easily be combined with any other HRC Product series at the other rebar end
On the construction site
- Straight bars are safer to handle than bend bars
- Fast installation of headed bars!
- Design with fewer bars and no anchoring bends reduces congestion and leads to improved casting conditions
