GFRP Rebars
GFRP Rebars (Glass Fiber Reinforced Polymer Reinforcement Bars) are advanced composite reinforcement products developed as a corrosion-resistant alternative to conventional steel reinforcement. Manufactured through a continuous pultrusion process using high-strength glass fibers embedded in a thermosetting resin matrix, GFRP rebars provide exceptional tensile strength, lightweight handling, and long-term durability in aggressive environments where steel reinforcement is susceptible to corrosion.
Unlike conventional reinforcement steel, GFRP rebars are non-corrosive, non-magnetic, electrically non-conductive, and resistant to chlorides, chemicals, moisture, and environmental degradation. These properties make them highly suitable for infrastructure, marine, coastal, industrial, transportation, and water-retaining structures requiring extended service life and reduced maintenance costs.
SREX Composites Private Limited manufactures high-performance GFRP reinforcement bars engineered to meet demanding structural requirements while delivering superior lifecycle performance and sustainability benefits.
GFRP Rebars are composite reinforcement bars manufactured using continuous E-Glass or high-strength glass fiber reinforcements impregnated with specially formulated resin systems and formed through a controlled pultrusion process. The external surface profile is engineered to provide excellent bond strength with concrete, ensuring efficient load transfer and structural performance.
Due to their superior resistance to corrosion and environmental attack, GFRP rebars are increasingly specified in projects exposed to seawater, de-icing salts, aggressive chemicals, high humidity, and stray electrical currents. Their lightweight construction significantly reduces transportation and installation costs while improving site handling efficiency.
Compared to traditional steel reinforcement, GFRP rebars offer a substantially higher strength-to-weight ratio, enabling long-term structural durability without corrosion-related deterioration.
