4X Lighter | 3X Stronger in Tensile Strength | Non-Corrosive | Green Solution

Steel rebar is still going strong, but MST-BAR® is built for the next century. Stronger, smarter, and backed by CCS service on every delivery.

Why We Recommend MST Rebar

Stop Corrosion

MST-BAR is non-corrosive. It won’t rust, crack the concrete, or cause expensive repairs, even in the harshest environments.

Stronger than Steel

MST-BAR delivers 3× the tensile strength of steel, stays straight, and will outlive the concrete it reinforces.

Easy To Handle

At ¼ the weight of steel, crews move it faster, safer, and cheaper, helping speed up the jobsite without needing extra equipment.

Frequently Asked Questions

MST-BAR is a glass-fiber reinforced polymer (GFRP) rebar with over three times the tensile strength of steel. It doesn’t rust or conduct electricity, and it lasts longer than the concrete around it. Steel can corrode and cause spalling, MST-BAR eliminates this issue.

Yes. MST-BAR is engineered for structural members, including beams, columns, walls, slabs, and footings. It is also built to handle seismic loading, resisting tension-compression cycles with high energy dissipation. Over 100 structures already use GFRP rebar in seismic regions.

MST-BAR carries ICC-ES Report ESR-4664, meets ACI 440, and complies with the IBC and IRC. It’s also engineered under AASHTO and CSA guidelines. This makes it fully acceptable for permitted construction when designed correctly.

Anywhere you’d use rebar. This includes parking garages, walls, slabs, bridges, seawalls, piers, roads, dams, pools, buildings, and more. It’s especially useful in Idaho for freeze-thaw cycles, de-icing chemicals, and moisture exposure.

Testing shows MST Rebar lasts over 100 years, thanks to its non-corrosive GFRP makeup. It won’t rust or break down, even in harsh environments. That means fewer callbacks and lower long-term costs.

Yes. It’s lightweight and easy to handle, and the ICC-ES report outlines simple storage requirements (keep it off the ground and protected from UV during long storage). Crews love it because it's a fraction of the weight of steel.
