Alkali-free glass fiber reinforced polymer (GFRP) bars are high-performance composite reinforcement bars made from alkali-free (E-glass) fibers and epoxy resin using a pultrusion process. They offer excellent properties such as high strength, light weight, corrosion resistance, fatigue resistance, and good electrical insulation, making them an effective alternative to traditional steel reinforcement in corrosive environments and special engineering applications.

With a tensile strength more than twice that of conventional steel bars and a weight only one-quarter of steel, E-glass GFRP bars are easier to transport and install. They also provide good bonding performance with concrete, significantly enhancing structural durability and extending service life. As an ideal upgrade material, they are widely used in municipal engineering, bridges, marine engineering, tunnels, underground works, and other fields.

Core advantages

  High strength: Tensile strength is significantly higher than ordinary steel reinforcement, effectively improving structural load‑carrying capacity.

  Corrosion resistance: Stable performance in harsh environments such as acid‑base, salt spray, and marine conditions; does not rust or corrode.

  Lightweight: Only one‑quarter the weight of steel, making transportation, handling, and construction more convenient.

  Good fatigue resistance: Maintains stable performance under long‑term cyclic loading, enhancing structural durability.

  Excellent electrical insulation: Non‑conductive, suitable for special electrical environments or projects with lightning protection requirements.

  Reliable bonding with concrete: Ribbed or sand‑coated surface design enhances grip with concrete, ensuring effective structural cooperation.

  Strong durability: Significantly extends service life and reduces long‑term maintenance costs.

Application area

  Municipal Engineering: Roads, bridges, culverts, drainage pipes, inspection wells, etc.

  Marine and Port Engineering: Breakwaters, docks, revetments, seawalls and other corrosive marine environments.

  Water Conservancy and Underground Engineering: Reservoirs, canals, tunnels, metro systems, diaphragm walls, etc.

  Chemical and Corrosive Environments: Chemical plants, sewage treatment plants, saltworks, acid-alkali tanks, etc.

  Structural Strengthening and Rehabilitation: Beam and column strengthening, slab strengthening, seismic retrofitting, etc.

  Lightning‑Sensitive and Electrical Applications: Substations, communication base stations, hospitals, laboratories, etc.

  Special Structures: Long‑span structures, lightweight structures, temporary works, precast components, etc.
