Classification

GFRP rebars can be categorized into fully threaded surfaces and sand-coated (grit-blasted) surfaces based on their surface profiles. Different surface textures result in varying bond strengths with concrete, allowing customers to select the optimal type for their project requirements.

Applications

  • Civil Engineering: Bridges, tunnels, highways, and retaining walls.
  • Marine Construction: Ports, piers, and seawalls exposed to saltwater.
  • Industrial Facilities: Chemical plants, nuclear stations, and cooling towers.
  • Renewable Energy: Foundations for solar farms and wind turbines.

Advantages

  • High Load-Bearing Capacity & Superior Tensile Strength: GFRP rebar offers twice the tensile strength of steel rebar of the same diameter, yet weighs only 1/4 as much.
  • Stable Elastic Modulus: Its elastic modulus (approximately 1/4 that of steel) ensures predictable deformation behavior under stress.
  • Electrical/Thermal Insulation: Features a thermal expansion coefficient closer to concrete, enhancing bonding integrity with cementitious materials.
  • Exceptional Fatigue Resistance: Ideal for structures subjected to cyclic stresses, extending service life in dynamic load environments.
  • High Impact Resistance: Suitable for applications requiring durability against sudden shocks or impacts.
  • Non-Magnetic with Superior Wave Transparency: Excellent for MRI facilities, telecommunications infrastructure, and other projects demanding electromagnetic neutrality.
  • Leichtes Design: Reduces transportation and installation costs while improving on-site handling efficiency.
