In the US, nearly fifty-seven million tons of traditional steel reinforcement bar (rebar) are used every year in the manufacturing of concrete. Torex International (now Polytorx LLC) developed a new steel fiber additive for concrete reinforcement, dubbed Helix. Originally designed for blast and earthquake resistant structures, Helix is toothpick sized, coated metallic wire that has been twisted into a helix shape. When millions of the small wires are dispersed into concrete, they lock into place, forming a strong matrix that increases the concrete's blast and impact resistance up to five times over traditional concrete.
As of 2007, Polytorx is growing rapidly, having exceeded $2 million in sales. In the process, the company has garnered major entrepreneurial awards, including the Michigan Technology Tricorridor Award, a National Science Foundation Small Business Innovation Grant, and the prestigious Carrot Capital Business Plan Competition.
