4MST-BAR a composite rebar, often called “fiberglass” rebar, certified for all structural applications. MST-BAR is Glass Fiber-Reinforced Polymer (GFRP) rebar and is an ASTM D7957 and ACI 440.11-22 certified. MST-BAR is a non-corrosive solution to replace epoxy-coated, galvanized, stainless and plain (black) steel rebar and provides reinforced concrete centuries of maintenance-free serviceability. Over 2X the tensile strength and a fraction of the weight of grade 60 steel rebar means it’s the perfect solution for concrete reinforcement. Key Advantages Corrosion-proof Reinforcement: Zero rust, zero spalling, eliminates costly rehabilitation and maintenance. 100+ Years Service Life: Engineered to extend the service life of your reinforced concrete for centuries. Quick & Simple Installation: Up to 50% labor savings compared to installing traditional steel rebar. Transportation Savings: Weighs 25% the weight of steel rebar. One truck of MST-BAR® replaces four truckloads of steel. High Performance in All Climates: Stronger reinforcement in freeze-thaw climates and guaranteed longevity in coastal regions. No Waterproofing: Eliminates need for costly waterproofing agents and epoxy coating necessitated by rust-prone steel rebar. MST-BAR® BEND Technology: Fastest turnaround time for factory fabricated bent bars. Our proprietary corrugated sleeve achieves any bend possible. Thermal Insulator: Increase your structure’s energy efficiency. Nonconductive & Nonferrous: Ideal for projects with electro-magnetic sensitivity. High Chemical Resistance: High alkaline resistance. Impervious to de-icing salts and other harsh chemical attacks. Environmental Sustainability: Environmentally friendly manufacturing leaves a fraction of the carbon footprint left by steel mills. High Fatigue Resistance: 20X higher resistance under cyclical loading compared to traditional steel rebar.
