MST Bar
MST Bar is the highest quality fiber glass rebar for building structures and non-structure applications.
Improving Construction With Super Form MST-BAR
Introducing MST-BAR, a fiberglass rebar for use with Super Form ICF. The glass fiber reinforced polymer (GFRP) material offers better tensile strength while being lighter than traditional steel rebar. With its unique properties and innovative design, it is redefining the standards for reinforcement in ICF blocks.
• Rust-Proof
Eliminates spalling and corrosion cracks.
• 200+ Years Service Life
Engineered to last for generations.
• Quick & Simple Installation
Up to 50% labor savings compared to traditional steel rebar.
• Transportation Savings
75% lighter than traditional steel rebar. Load on your truck’s ladder rack, no Class-A CDL required.
• High Performance in All Climates
Stronger reinforcement in freeze-thaw regions and guaranteed longevity in corrosive coastal regions.
•No Waterproofing Required
Eliminates need for costly waterproofing agents and epoxy coating necessitated by rust-prone steel rebar.
• Exceptional Strength
Over 4x stronger than Grade 40 rebar.
• Nonconductive & Nonferrous
Ideal for projects with electromagnetic sensitivity.
• Superior Crack Control
80% less crack initiation compared to traditional steel rebar.
• Chemical Resistant
Impervious to de-icing salts and other chemicals.
Why do builders and contractors prefer it over steel rebar?
Builders and contractors are discovering the labor savings that come with the use of MST-BAR fiberglass rebar.
Specifically, MST-BAR is
- 4x lighter than steel
MST-Bar allows workers to install rebar with ease and reduce workplace injury.
Saving labor reduces the time builders and contractors are on each job site. The installation of MST-BAR fiberglass rebar:
- takes half the time to install with half the number of workers
- requires ZERO maintenance and repairs
Builders experience an increase in productivity with MST-BAR, allowing them to achieve more projects in a month or the same amount of projects.

Why should I use MST-BAR for reinforcing concrete structures?
MST-Rebar is a fiberglass rebar that is specifically engineered and designed with an Integral Rib that mechanically locks it into concrete.
Unlike every other rebar, including traditional steel rebar and other fiberglass rebars, the only way to pull it out of the concrete is to break the concrete itself.
No other glass fiber reinforced polymer (GFRP) rebar, and certainly not steel rebar, can compete with MST-BAR's:
- 3x bond strength
- 3x tensile strength
- 20x fatigue resistance
MST-BAR is a more durable solution to concrete reinforcement.

What are the other benefits of MST-BAR over steel rebar?
Other benefits of MST-BAR over traditional steel rebar include
- Non Corrosive (suited to any environmental exposure)
- Non Conductive (does NOT conduct heat, cold, or electricity)
- Easy to Transport (75% lighter than steel, saving on shipping costs)
