What is Fiberglass Rebar?

Fiberglass rebar is a type of reinforcing bar made from glass fibers and resin. It is known for its high strength, lightweight nature, and resistance to corrosion. These properties make it an ideal choice for various construction projects, especially those in harsh environments where traditional steel rebar would deteriorate quickly.

Key Benefits of Fiberglass Rebar

  1. Corrosion Resistance: Unlike steel, fiberglass rebar does not rust, making it perfect for use in marine environments, chemical plants, and other corrosive settings.
  2. Lightweight: It is significantly lighter than steel, reducing transportation and handling costs.
  3. High Tensile Strength: Fiberglass rebar has a high tensile strength, making it suitable for high-stress applications.
  4. Non-conductive: It does not conduct electricity or heat, which is beneficial in certain industrial applications.
