Product Overview

Alkali-resistant glass fiber reinforced polymer (GFRP) bars are high-performance composite reinforcements made from alkali-resistant glass fibers and resin, produced through a pultrusion process. These bars offer excellent alkali resistance, corrosion resistance, high strength, light weight, and electrical insulation, making them an ideal alternative to traditional steel reinforcement—especially in high-alkalinity concrete and corrosive environments.

Core advantages

    Superior alkali resistance: Maintains stable performance in high-alkalinity concrete and is not degraded by alkali.

    High strength and light weight: High tensile strength with low density, easy to transport and install, and helps reduce overall project costs.

    Corrosion resistance: Does not rust and is resistant to acids, alkalis, and salts, suitable for harsh environments such as marine and chemical industries.

    Good electrical insulation: Non-conductive, avoiding stray current corrosion and making it ideal for electrically sensitive projects.

    Excellent aging resistance: Long service life with stable performance under UV, humidity, and other harsh conditions.

    Strong bonding with concrete: Special surface treatments enhance grip and bonding performance with concrete, improving structural stability.

Application area

    Municipal engineering: Roads, bridges, culverts, drainage pipelines, etc.

    Water conservancy engineering: Reservoirs, canals, dams, sewage treatment facilities, etc.

    Marine engineering: Seawalls, breakwaters, docks, and other high-salt environments.

    Chemical anti-corrosion engineering: Chemical plants, acid-alkali tanks, salt works, etc.

    Underground engineering: Tunnels, metro systems, diaphragm walls, etc.

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

    Electrically sensitive projects: Substations, communication base stations, laboratories, etc
