Standard Specification for Solid Round Glass Fiber Reinforced Polymer Bars for Concrete Reinforcement
STANDARD published on 15.11.2025
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers glass fiber reinforced polymer (GFRP) bars, provided in cut lengths and bent shapes and having an external surface enhancement for concrete reinforcement. It specifies the property limits and test methods for qualification, quality control and certification of GFRP bars, the geometric and mechanical property requirements, and minimum inside bend diameter of bent bars. Physical properties include fiber mass content, glass transition temperature, degree of cure, and bar sizes), whereas mechanical properties include ultimate tensile force, tensile modulus of elasticity, ultimate tensile strain, transverse shear strength, and bond strength.
