High-Strength Steel Reinforcing Bar

Current US building codes for rebar strength were last updated in the late 1960’s based on 50’s and 60’s era research. These codes limit rebar strength to 60 ksi. US rebar mills can now produce suitable rebar up to 100 ksi. In many parts of the world, rebar strengths of 100 ksi and above are used routinely.

Since 2013, CPF has led a systematic initiative – from strategic planning through research – to lay the groundwork for code changes that will bring US rebar standards into the 21st century. This initiative will allow engineers to capitalized on advances in steel metallurgy, and implement designs comparable to practice and standards throughout the world.

This issue goes well beyond rebar costs. The results will have a significant impact on construction quality, productivity, and sustainability.
