ICC-ES Report Issued to Expand Number of Bar Sizes of DYWIDAG Grade 100 THREADBAR® and Confirms Superior Strength and Performance

Bolingbrook, Illinois – March 21, 2017 – DYWIDAG-Systems International USA, Inc. (DSI) announced today that its DYWIDAG Grade 100 THREADBAR® report has been reissued by the International Code Council Evaluation Services (ICC-ES) to now incorporate bar sizes #11, #14, #18 and #20.


DSI produces and offers its full size range (#6 through #20) in GR100 and has now secured this important ICC-ES report for the key sizes for vertical reinforcing applications where Grade 100 reinforcing is seeing growing acceptance in the construction industry.

Also, the report confirms that DYWIDAG Grade 100 THREADBAR® has minimum 100ksi yield strength in both tension and compression - a feature unmatched by any competing, approved threaded reinforcing bar product in the industry. The DYWIDAG Grade 100 THREADBAR® is the only Grade 100 bar product conforming to both acceptance criteria AC237 and specification ASTM A615-15 and therefore offers unmatched benefits in terms of strength, savings associated with the use of high-strength bars, and quality.

The advantages of using DYWIDAG Grade 100 THREADBAR® are significant, including lower fabrication, installation (both labor and crane time) and freight costs due to the lower overall weight as fewer reinforcing bars are required. All of this results in reduced overall cost and shortened construction schedule.

Kerry Allen, President and CEO of DYWIDAG-Systems International USA, Inc. says: “We are excited to be able to offer this product line which is superior to anything currently available in the market and which will allow owners and designers a fully domestic option to improve their design and performance while also reducing over-all construction costs.”

DYWIDAG Grade 100 THREADBAR® is designed for maximum performance and is produced under an exclusive partnership with Gerdau in their St. Paul Minnesota mill facility by United Steel Workers of America union members and using fully domestic USA steel thus conforming to all Buy America requirements.
