HELIX® 8-52 MICRO REBAR®: A Superior Concrete Reinforcement Solution
The unique, twisted design of Helix® Micro Rebar® 8-52 allows for efficient tensile stress redistribution within the concrete prior to concrete cracking. This pre-crack property is coupled with solidly stable post-crack performance. The post-crack performance is optimized for the requirements of standardized beam tests. Helix Micro Rebar provides proactive reinforcement coupled with unheard-of resistance if a crack were to occur.
What Is Helix® Micro Rebar?
Helix® Micro Rebar® is an innovative concrete reinforcement technology made up of 1-inch, twisted steel elements that are blended uniformly into the concrete mix. Because each piece is twisted, it creates a mechanical anchoring effect—very different from the friction-based interaction found in conventional steel fibers. Think of it like driving a screw into wood rather than simply pressing something against the surface.
This mechanical bond plays a key role in stopping micro-cracks from developing and spreading. By distributing reinforcement in every direction throughout the concrete, it forms a dense, multidirectional support network.

The Helix Advantage — Beyond Traditional Steel Fibers
Helix® Micro Rebar® strengthens concrete by preventing cracks from forming in the first place, while many other fiber options only act after cracks have appeared. The patented twist provides a superior bond compared to the friction-based hold of standard steel fibers, resulting in more dependable and durable performance.
Because it helps control the earliest stages of cracking, this technology enhances the concrete’s resistance to fatigue, impact forces, and seismic activity. Each steel element is also coated with zinc, adding an extra layer of protection against corrosion.

Save Time
Every 10,000 sq. ft. of rebar replaced with Micro Rebar® saves one full day of construction.
Save Money
Using Micro Rebar® allows contractors to simplify operations, dramatically reducing project costs.
Stand Out
Micro Rebar® doesn’t just meet code and reduce project costs, it’s also easier to use than rebar and mesh—allowing engineers to set themselves apart with clients.
Proven for 20 Years
After two decades, more than 100 million square feet of slabs and more than 20,000 vertical structures, the results speak for themselves.
Increases Strength
When compared to Rebar, Helix Micro Rebar® can increase fatigue resistance by up to 300% and the flexural strength by up to 33%.
3rd Party Accredited
Micro Rebar® has been certified by the International Code Council Evaluation Service (ICC-ES) and Uniform Evaluation Service (IAPMO-ES).
Have a specific application in mind?
Find out how Helix Micro Rebar® can work for you.

Because it locks into the concrete, Micro Rebar® increases the amount of force that would be required to crack it. It would actually have to untwist to pull apart, which is a completely new failure mechanism that makes Micro Rebar™ better than other options.

Specify Helix
Helix® Micro Rebar® Reinforcement Three Part Specification
Specifying Helix® steel reinforcement is simple. Here you will find the necessary CSI formatted specification template. Also available are partially completed substitution forms for during the bidding process and after. Add Helix® reinforcement to the drawings in a note, do not remove the original design. This gives the contractor and building official the opportunity to choose.
The note should say: “use the original reinforcement shown in the drawing or Helix® 5-25 at x lb/yd3 designed and installed in accordance with UES ER 0279 or ICC-ES ER 3949″. We recommend also indicating that the manufacturer should have at least 10 years experience manufacturing and requiring that the manufacturer also have ISO 9001 Certified Quality Management System.
