Enhanced Safety

The light weight of Mateenbar60™ simplifies handling, minimizes installation risks, & reduces workplace injuries—contributing to safer worksites & reducing material waste for a more sustainable future.

Mateenbar is much lighter than traditional steel sections and this allowed the contractors to have less staff making the large reinforcing cages. The lighter weight material reduced the risk of damage to the sensitive heritage monument. The team from Mateenbar were great to work with. They fabricated profiles and materials that were ideal for the application.

What Is Mateenbar60™ Used For?

Mateenbar60 is a rust-proof, lightweight structural rebar designed to reinforce concrete in heavy infrastructure and government projects. It is the primary reinforcement to provide resistance for the load stresses on the concrete structure according to ACI440 / ASTM D8505 standards and replaces epoxy-coated steel, galvanised steel and stainless steel where durability and maximum performance are critical. Its stiffer modulus of 8700 ksi (60 GPa) makes it ideal for large-scale applications, including bridges, highways, seawalls, industrial facilities, and other heavy-duty construction.

Is Mateenbar60™ Approved by the Building Codes?

Mateenbar60 complies with key building codes and standards established by leading industry institutions such as ASTM, ACI, and ICC. These standards and evaluations ensure Mateenbar60 meets the stringent requirements for safety, performance, and reliability in residential and commercial construction. While specific building codes can vary by jurisdiction, Mateenbar60’s compliance with these widely recognized standards simplifies the approval process for use in many projects. For detailed information, consult your local building authority.

Is Mateenbar60™ Affected by Alkaline Conditions?

No, Mateenbar60 is not significantly affected by alkaline conditions. It is manufactured with ECR glass fibers, which are resistant to attack from alkaline conditions and a specialized resin matrix that provides excellent resistance to the high-alkaline environments typically found in concrete. This ensures long-term durability and performance, even in harsh conditions, making it a reliable reinforcement choice for a wide range of applications.

Does Mateenbar60™ Have a Ductile Failure?

Mateenbar60 does not experience ductile failure like steel. Instead, it exhibits a linear elastic behavior until it reaches its ultimate strength, at which point it will fail in a brittle manner consistent with the properties of FRP materials without significant deformation. The design standards for GFRP rebar like Mateenbar60 allow for this property by incorporating safety factors and providing reliable and long-lasting reinforcement.
