Helix 8-50 has a nominal length of 2 inches and an equivalent diameter of 0.30 inches which meets specification ASTM A820 - Type I. Helix 8-50 combines our proactive concrete reinforcement technology with a longer length that provides superior post-crack behavior.

Helix Steel’s patented anchorage technology uses a continuous deformation along the length of the shaft in the form of twisted ribs rather than a smooth shaft with hooks at each end. This provides a continuous anchorage in concrete and stable pre- and post-crack behavior as opposed to smooth steel fibers that rely on small end hooks.
