Helix® Micro Rebar® — A Superior Alternative to Standard Steel Fiber
The construction industry has traditionally relied on standard rebar and mesh for concrete reinforcement. These methods have drawbacks, such as being labor-intensive and time-consuming, and they only deliver results after cracks form.
At Helix Steel, we are making the entire industry rethink concrete strength. Our revolutionary Helix® Micro Rebar® product offers a more proactive concrete reinforcement solution that improves the material from within.
What Is Helix® Micro Rebar®?
This advanced micro rebar reinforcement product consists of 1-inch twisted steel components mixed directly into the concrete. The twist forges a mechanical bond, which differs from the friction-based bond of standard steel fibers. The twisting process is similar to screwing a fastener into a piece of wood.
The primary benefit of this micro rebar concrete reinforcement process is that the bond effectively prevents small cracks from forming and propagating. It also creates a comprehensive multidirectional reinforcement matrix through the entire concrete volume.

The Helix Advantage — More Than Just a Steel Fiber
Our micro rebar product protects concrete more effectively by stopping cracks before they start. Other fibers can only stop cracks after they appear. Additionally, the patented twist forms a stronger bond than the friction generated by traditional steel fibers, ensuring more reliable, long-lasting results. These micro rebar products integrate seamlessly into mixes for improved structural performance. This approach offers a streamlined form of steel reinforcement for concrete compared to conventional rebar systems.
The ability to control micro cracks means our steel fiber provides increased fatigue, impact, and seismic force resistance. We also apply a zinc coating to the steel material to protect against corrosion. This performance advantage exceeds that of many traditional steel fiber reinforcement products — ideal for producers seeking advanced micro fiber concrete solutions that outperform basic fibers.
Key Benefits of Helix® Micro Rebar® Reinforcement
Helix solutions are among the leading rebar alternative products designed to simplify reinforcement workflows. Micro rebar concrete reinforcement offers numerous benefits:
- Speed: Our micro rebar saves one day of construction per 10,000 square feet by eliminating rebar placement and tying, significantly reducing project completion times.
- Reduced labor and project costs: One of the best alternatives to rebar, Helix micro rebar offers faster construction times and less on-site labor, resulting in more efficient manpower usage and can reduce overall project costs by up to 20%.
- Enhanced safety: Our product helps you create a less hazardous jobsite by reducing the physical strain and tripping risk posed by traditional rebar. This reinforced steel for concrete enhances durability and performance from placement through the life of the structure.
- Increased versatility: Helix® Micro Rebar® is suitable for a wide range of construction applications, such as walls, foundations, slabs, infrastructure, and precast concrete. While often grouped with steel fiber reinforcement, Helix® Micro Rebar® behaves more like distributed rebar within the concrete.
- 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. By integrating directly into the mix, Helix® Micro Rebar® provides efficient steel reinforcement for concrete without traditional bars or mesh.
- 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.
- Third-party accredited: Micro Rebar® has been certified by the International Code Council Evaluation Service (ICC-ES) and Uniform Evaluation Service (IAPMO-ES).

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.

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.
