Blackbends™
Blackbends are Mateenbar’s factory-formed structural GFRP shapes for applications where straight bars are not
enough. Made to your project specifications in sizes #3 through #8.
Manufactured in the United States and made from durable Glass Fiber Reinforced Polymer (GFRP), Mateenbar60™ is corrosion-free, chemical-resistant, and engineered to deliver a sustainable 100-year design life with no maintenance required, outlasting steel in even the harshest environments.
Designed for heavy industrial projects and larger structural applications, Mateenbar60™ combines trust, quality, and performance to meet your structural reinforcement needs. Despite its lightweight nature, Mateenbar60™ boasts high tensile strength, making it a dependable choice for bridges, multi-story buildings, and other demanding infrastructure projects.
Distinctive Features
Mateenbar60™ is not your typical fiberglass rebar. Our engineers ensure that our GFRP products stand above the competition, with unique features including a buffed, and helically ground rib design that is optimized for superior bond strength with concrete. This innovative form factor ensures a long shelf life without deterioration and makes for easy handling.
Industry Codes and Standards
Mateenbar60™ meets or exceeds all applicable industry codes, standards, and specifications, including:
- ASTM D8505
- ACI 332
- ACI 440
- ICC-ES 5548.
At Mateenbar®, we are committed to delivering reliable concrete reinforcement the industry can trust.
Advantages of Mateenbar60™ over Steel Rebar
🚫
Corrosion Resistant
Unlike steel, Mateenbar60™ will never rust or corrode, even in harsh saltwater, chemical, or high-moisture environments. No epoxy coatings required.
⚖️
Lightweight
Roughly 75% lighter than steel rebar, reducing shipping costs, labor fatigue, and overall project weight without sacrificing performance.
⚡
Non-Conductive
Electrically and thermally non conductive, making it ideal for sensitive infrastructure, rail, and environments where stray currents are a concern.
💪
High Tensile Strength
Mateenbar60™ delivers tensile strength exceeding ASTM D8505 minimums, outperforming conventional steel in demanding structural applications.
Sizing & Options
Prefabricated Bent Bars
- Manufactured in-factory in standard diameters
- Standard bent shapes can be special order
- Compatible with most steel bent shapes with exceptions like “Z” shapes
- Bending is factory-performed only; shapes and quantities must be specified by the contractor
- Strength reduction due to bending is factored into design specifications
Straight Bars (Mateenbar60™)
- Available in standard steel diameters (#3 to #8)
- Stock lengths: 20’, 30′ and 40’
- Pultrusion manufacturing enables a wide range of diameters and virtually unlimited lengths
- Priced per linear foot, offering cost transparency and flexibility
Applications
Bridge Systems
Composite reinforcement provides a durable alternative to conventional steel in bridge and transportation infrastructure, particularly in environments exposed to moisture, deicing salts, and corrosion.
Shoreline Recovery
Shoreline and marine infrastructure faces constant exposure to saltwater, moisture, and harsh environmental conditions. Composite reinforcement offers a corrosion resistant solution for seawalls, bulkheads, docks, retaining systems, and other coastal structures.
Industrial Infrastructure
Industrial environments often expose structures to chemicals, moisture, heavy use, and other demanding conditions. Composite reinforcement provides a durable, corrosion resistant solution for processing facilities, utility infrastructure, foundations, floors, and other reinforced concrete applications.
