Material and Structure: Glass fiber-reinforced unsaturated polyester / epoxy modified resin; the predominant design is the sandwich impedance composite structure (the sound-absorbing surface faces the noise source: perforated FRP panel + hydrophobic centrifugal glass wool/rock wool core material + FRP back panel); the surface is often matte gray/green/blue, with customizable landscape features/transparent strips; complies with standards such as HJ/T 381, GB/T 23483, and JT/T 646; high-quality SMC/pultruded products have a lifespan of 15–20 years.
Forming Process: SMC molding (high dimensional accuracy, stable batch production), extrusion molding (efficient for long strips), hand layup (customized for irregular shapes); common specifications for unit panels: 2000mm × 500mm × 100mm, overall height 2.5–4.0m (depending on noise reduction requirements and road red lines); surface density 12–16 kg/m², much lighter than concrete/metal panels.
System components: screen unit + steel/FRP column posts + foundation + sealing/electrical storm protection accessories; sound-absorbing surface perforation rate: 20%–25%, core material density: 48–64 kg/m³, water repellency rate ≥98%.

Product Advantages
High-efficiency noise reduction: The noise reduction for mid-to-high frequencies (the main frequency range of traffic) can reach 25–35 dB(A). The noise reduction coefficient (NRC) is ≥0.8, and the sound insulation rating (Rw) is ≥30 dB. It can suppress diffraction and protect sensitive areas (residential areas, schools, hospitals).
Lightweight, high strength, weather-resistant: density approximately 1.8 g/cm³ (steel plate 1/4, concrete 1/5); can be easily carried by one person; quick for high-altitude/traffic-disrupting construction; resistant to wind loads up to 12 levels, stable at temperatures ranging from -40°C to 80°C over an extended period; resistant to ultraviolet rays, acid rain, coastal salt fog; no corrosion.
Insulated and maintenance-free: non-conductive, no need for anti-corrosion coatings; the hydrophobic core material does not absorb water or form clots, so routine checks on fasteners are sufficient, and maintenance costs are extremely low.
Landscaping and Environmental Protection: Customizable colors, shapes, and transparent PC board strips; flame-retardant formulation, low smoke, non-toxic, meets environmental and fire safety requirements.
