Word-of-the-Month: Rebar


Rebar, short for reinforcing bar, is a steel bar that is used to reinforce concrete. Concrete has strong compression strength, but weak tensile strength. The rebar is used as a tension device to increase the concrete’s tensile strength, providing more stability to a structure. 

Fun Fact
In the 18th Century, a cast iron rebar was used in the Leaning Tower of Nevyansk in Russia. Due to the high quality of steel used, there has not been any corrosion on the rebars to this day. Additionally, the embedded rebars in the structure were not recognized for their greatness until the mid-19th Century, which led to the development of modernized reinforced concrete.

Stahl used steel rebars to reinforce the large concrete walls at new 135,000-square-foot Army National Guard Readiness Center in Arden Hills, MN.
