Founded in 1924, the Concrete Reinforcing Steel Institute (CRSI) is a technical institute and Standards Developing Organization (SDO) that stands as the authoritative resource for information related to steel reinforced concrete construction. CRSI offers many industry-trusted technical publications, standards documents, design aids, reference materials, and educational opportunities.

Approximately 8 million tons of reinforcing steel (rebar) is manufactured per year using scrap steel in efficient manufacturing operations. It is estimated that the industry impacts over 75,000 people in steel transportation and placement.

CRSI members include manufacturers, fabricators, material suppliers, and placers of steel reinforcing bars and related products as well as professionals who are involved in the research, design, and construction of steel reinforced concrete. CRSI members employ approximately 15,000 people in steel production and rebar fabrication at over 450 locations in 47 states throughout North America.

The non-profit CRSI Research & Education Foundation fosters the educational and research mission of the Institute through educational programs and scholarships for students majoring in civil engineering, architecture, and other related disciplines at universities and technical schools. The Foundation also supports research fellowships and projects, which will ultimately advance the reinforced concrete industry. CRSI is headquartered in Schaumburg, Illinois, with regional offices located across the United States.
