GlassFiberReinforcedPolymer (GFRP), these rods are composite materials that are made of fiberglass combined with polymeric resins, ideal for reinforcing base slabs are used as an alternative to traditional steel bars in construction and structural reinforcement due to their unique properties. This bar does not rust, is lighter, does not conduct electricity and presents a high durability, making the structures where they are applied have a considerably longer useful life.
