Headed Bars

Headed Bars

Anchorage alternative to hook bars and long development length

Headed Bars are a simple and effective alternative to hooks and long development length.

A compact disc is mounted onto the reinforcement bar end. The assembly of the rebar and the anchor provides a anchorage superior to long straight or bent reinforcement bars, while being simpler and faster to install.

Headed Bars contribute to reducing rebar congestion in heavily reinforced area, which ultimately eases the compaction process and result in better concrete quality in key areas of the structure.


Product features

  • Made of an anchor plate that is screwed onto the end of the reinforcement bar.
  • Headed Bars are a convenient alternative to hooks in congested areas.
  • Anchors are available into two standard sizes to provide a net bearing area 4 or 9 times equal to the cross section area of the bar.
  • Requires the same bar end preparation as Dextra coupler systems and compatible with Bartec, Fortec, Griptec and Rolltec threads.


Reduce congestion
and allow the use of larger rebar.
Install in a few seconds
Install in a few seconds
even after the reinforcement has been installed.
with Dextra Bartec, Fortec, Griptec and Rolltec systems.

Benefits of Headed Bars

As main reinforcement :

  • Less congestion.
  • Ease of installation. Threaded heads can be fitted on site after rebar installation.
  • No more risk of rebar embrittlement due to bar bending.
  • Require shorter anchorage (development) length.
  • More faithful realization of strut-and-tie modeling.
  • Better anchorage effectiveness (lower bearing stress and less slip) especially on large diameter bars

As transverse reinforcement :

  • Shear reinforcement in slabs and footings.
  • Cross ties in walls, columns and diaphragm walls.
  • Faster installation time.
  • No more site bending of double-headed 135° or 180° hooks.
  • Allow use of larger bars, therefore decreasing the quantity of links.
