Fiberglass reinforced plastic sound barrier

Fiberglass Reinforced Plastic (FRP) is a material composed of glass fiber (reinforcing material) and resin (matrix material), combining the high strength of the fiber and the corrosion resistance of the resin. Based on this characteristic, the structural design of FRP acoustic barriers usually revolves around the noise reduction logic of "combination of absorption and isolation".

Core CharacteristicsSpecific Parameters & AdvantagesDifferentiated Highlights vs. Traditional Materials
Lightweight & Easy to Install1. Density is only 1/4 of steel and 1/3 of cement2. A standard single panel (2m × 1m) weighs 15-30kg3. No need for heavy lifting equipment; installable manually or with small machineryReduces construction costs and lowers load-bearing requirements for foundational structures like bridges and elevated roads, significantly decreasing construction thresholds and costs
Weather & Corrosion Resistance + Long Service Life1. Resin matrix offers exceptional resistance to acids, alkalis, UV rays and aging2. Operating temperature range: -40°C to 80°C; rust-free and corrosion-free3. Service life: 15-20 years, with only regular cleaning required for maintenanceSolves the pain points of metal noise barriers (prone to rust) and cement noise barriers (prone to weathering), resulting in extremely low post-maintenance costs
Flexible Shape & High Landscape Adaptability1. Integrally molded with custom molds, supporting special-shaped structures like arcs and waves2. Surface can be sprayed with imitated wood grain, imitated stone textures or printed with patternsIntegrates seamlessly with surrounding environments (parks, residential areas, scenic spots, etc.) and avoids the "visual oppression" caused by traditional noise barriers, with stronger landscape compatibility
Stable Mechanical Properties1. High impact resistance and flexural strength thanks to glass fiber reinforcement2. Flexural strength reaches 120-180MPa3. Withstands airflow impact and gravel collision from moving traffic, resistant to deformation and crackingBalances lightweight and structural stability, meeting the long-term application requirements of traffic scenarios
