Metal anchor rods have received widespread attention in the engineering community due to their corrosion issues, greatly affecting the application range and engineering lifespan of geotechnical anchoring technology, especially in many special geological formations and permanent geotechnical anchoring engineering applications, which are greatly limited. The main component of fiberglass anchor rod is corrosion-resistant material, which has the characteristics of high strength, light weight, impact resistance, corrosion resistance, and good dielectric performance.

Due to the corrosion resistance, fatigue resistance, and excellent mechanical properties of fiberglass anchor rods, foreign countries have replaced steel bars with GFRP bars in concrete structures, attempting to fundamentally solve the durability problem of concrete structures and achieving good results. Many foreign companies have been widely applied in engineering practice, with tunnels and slopes being the most common. The countries of application include the United States, the United Kingdom, Germany, Italy, Norway, Sweden, Belgium, Australia, etc. Examples of application include HBL/HBCM (coal mines in France), Cape Breton Coal (coal mines in Canada), Coal Mine Chile (coal mines in Chile), Gengiols (railway tunnels in Switzerland), Chlos tunnel (road tunnels in Switzerland), Langeten Stollen (Wateradit drainage tunnel in Switzerland), Road A42 (slope stability in the UK), and Hoben Salzburg (roads in the US). Tunnels, etc.
