Lightweight - corrosion resistant GFRP rebar

Glass fiber reinforced polymer (GFRP) rebar the major advantages of being a lightweight and corrosion-free alternative to steel reinforcement. GFRP rebar offers high tensile strength, stiffness-to-weight ratio, solid resistance to corrosive chemicals, electromagnetic neutrality, excellent fatigue properties, and control over thermal expansion.

GFRP rebar is a lightweight corrosion resistant rebar made using glass fiber reinforced polymer (GFRP). Compared with traditional steel bars, GFRP steel bars have many advantages, such as high strength, light weight, corrosion resistance, non-conductive, non-magnetic and easy processing, etc. In addition, GFRP steel bars also have good insulation properties and fatigue properties, which can maintain strength and stiffness during the life cycle. GFRP steel bars are widely used in a wide range of applications, especially in concrete structures, such as bridges, tunnels, docks, underground facilities, houses, etc. Compared with traditional steel bars, GFRP steel bars perform well in terms of tensile, compressive and bending resistance, and are more resistant to corrosion, and are better used in high humidity and marine environments.

GFRP Rock Bolts have a high corrosion resistance under acid conditions and are well suited for permanent support. The improved flexibility of long tendons is well suited for application without couplings in confined locations.

GFRP hollow rockbolt is mainly used as grouting anchor, use cement&resin and other material as adhesives, could bonding main item with rockbolt, improve support ability.

At present, the glass fiber reinforced bars on the market already have good cuttability. Due to the light weight and toughness of the material itself, some traditional cutting tools, such as electric saws, steel hammers, and pliers, can be used for processing. In addition, there are also some special fiberglass rebar cutting tools, such as abrasive cutting machines, electric saw cutting machines, etc., which can be cut more conveniently and quickly. It should be noted that when cutting glass fiber reinforced bars, attention should be paid to safety, to avoid dust and other harmful substances, and the accuracy and quality of cutting must be guaranteed, otherwise the use effect and safety may be affected.

Glass fiber reinforced polymer bars are a high tensile strength alternative to steel reinforcements. It has strong corrosion resistance and can greatly extend the service life of concrete structures.
