Reduced Congestion with T-Headed Bars:

Reduced congestion

Avoid installation errors and problems with field tolerances:

Not to standards   Reduced anchorage capacity
Typical situation at site:
not according to the standards
Left: Reduced anchorage capacity
Right: Full anchorage with T-heads

Improved robustness at overload and accidental conditions:

Improved robustness

Concentrated anchorage, no bond length required:

Concentrated anchorage

The concentrated and stiff anchorage properties of headed bars are not dependent on a bond length to develop the full tensile strength of the reinforcement in concrete; 100 % anchorage at the head.

Stiff anchorage:

Stiff anchorage graph

HRC group has conducted a series of tests documenting the T-headed bars unique strength and performance. Please contact us for more information.

  • All products are designed to exceed the actual stress and strain capacity of the rebar.
  • Head dimensions for HRC 100 series are based on concrete compressive strength of 30MPa. Higher concrete strength results in more conservative design.
  • T-heads of HRC 200 series have improved resistance under fatigue loads.
  • Mechanical properties that fulfill the ductility requirements for reinforcement steel with a charasteristic yield strength of 500 MPa in accordance to EN 10080.
  • Can be combined with 180° hook or other HRC products:

t-headed bars

  • Series 100 and 200 are available in lengths 200–18 000 mm.
