FIBERGLASS REBAR (GFRP)

FIELDS OF APPLICATION

 

Introducing GFRP rebar

GFRP, or Glass Fiber Reinforced Polymer, is a composite material that has the potential to be transformative in various constructive industries. GFRP Rebar is an economical, safe, and long-term sustainable solution, offering both initial and long-term cost savings. Fiberglass rebar has enjoyed a rise in popularity thanks to the many key advantages it offers over its steel rebar. Choosing FRP rebar is a commitment to quality, innovation, and an investment in the safety of future objects.

Benefits of composite rebar

  • Excellent corrosion resistance. GFRP rebar effectively resists corrosion and so can last much longer than standard rebar. Composite rebar minimizes maintenance needs.
  • Highly Chemical Resistant.  GFRP rebar resistant to chemical acids, salt ions, and the inherent alkaline bases of concrete that cause premature deterioration.
  • Lightweight. FRP rebar is 9 times lighter than steel, making it easier to transport and install.
  • High Strength. Despite its lightweight properties, GFRP rebar offers impressive strength-to-weight load-bearing performance.
