Glass Fibre Reinforced Polymer-GFRP Rebars are reinforcement materials employed in the construction of concrete. Their corrosion resistance makes them a cost-saving, long-term option for reinforced coastal concrete, bridges, and parking garages. They have better durability in extreme environmental conditions, prolonging the structure's lifespan. The lighter quality assists in lessening the total weight of the structure, something that may be of concern for some forms of construction, like high-rise buildings or retrofitting work. Glass Fibre Reinforced Polymer-GFRP Rebars provide a better substitute to ordinary steel rebars in concrete reinforcement, especially in conditions where water exposure, salt, or harsh chemicals are present.
Designed to meet Bharats growing infrastructure needs with precision and quality, we are crafting premium GFRP Rebars in Ahmedabad. Our products meet the highest standards of Bureau of Indian Standards IS-18256:2023 and other International Standards.
GFRP Rebars is a revolutionary solution to corrosion vulnerabilities. We offer unparallel resistance to chloride-ion attacks, providing a robust alternative for non-prestressed reinforcement in concrete elements subjected to flexure, shear, and compression loads. These composite rebars have a tensile strength upto 2x greater than traditional steel yet, weigh a mere 25% of their steel counterparts. Furthermore, GFRP Rebars serve as excellent electromagnetic and thermal insulators
