Summary：HDPE high vertical sand barriers are hollow wind-sand protection panels integrally extruded and perforated with high-density polyethylene (HDPE) as the base material, blended with UV-resistant, anti-ageing and salt-alkali resistant modifiers. Based on aerodynamic principles, their hollow pores reduce wind speed near the ground, trap drifting sand and hinder the advance of sand dunes. They serve as mainstream engineering sand control materials for railways, highways, Gobi deserts, photovoltaic and wind power bases, and ecological restoration in mining areas.

HDPE High Vertical Sand Barriers
HDPE high vertical sand barriers are hollow wind-sand protection panels integrally extruded and perforated with high-density polyethylene (HDPE) as the base material, blended with UV-resistant, anti-ageing and salt-alkali resistant modifiers. Based on aerodynamic principles, their hollow pores reduce wind speed near the ground, trap drifting sand and hinder the advance of sand dunes. They serve as mainstream engineering sand control materials for railways, highways, Gobi deserts, photovoltaic and wind power bases, and ecological restoration in mining areas.
Core Material & UV Resistance Properties
Base material: Virgin HDPE for HDPE high vertical sand barriers, no recycled materials blended. Density ranges from 0.94 to 0.96 g/cm³. All modifiers are uniformly compounded into the substrate instead of surface coating. The UV stabilizers exist throughout the panel, so anti-ageing performance remains intact after cutting and drilling. This effectively prevents yellowing, pulverization and brittle cracking of panels under intense solar radiation in desert regions.
Temperature resistance: -60℃ ~ +80℃. Adaptable to drastic day-night temperature fluctuations in Gobi areas; no brittle fracture at low temperatures and no deformation under high temperatures.
Environmental durability: Resistant to salt-alkali corrosion and wind-sand abrasion. Rust-free and rot-proof, and maintains stable performance even when partially buried by sand.
Designed service life: 10–15 years, far exceeding straw sand barriers (1–2 years) and ordinary metal meshes (3–5 years).
Main Technical Parameters of HDPE High Vertical Sand Barriers (Customizable)
- Panel thickness: 2.0 mm / 2.5 mm / 3.0 mm / 4.0 mm / 5.0 mm
- Standard dimensions: Length 2–3 m, panel height 1.0–2.0 m; custom cutting available upon request
- Open area ratio (porosity): 30%–50%; 30%–40% commonly adopted in projects. Hole patterns and aperture sizes can be adjusted according to wind tunnel test requirements
- Tensile strength: ≥22 MPa; Elongation at break ≥300%. Excellent toughness against strong wind impact and resistant to tearing during sandstorms
- Color: Engineering green (other colors available on request)
- Accessories: Pre-drilled mounting holes on panels. Can be assembled into vertical sand barriers with steel posts or anti-corrosion posts
Sand Blocking Mechanism
The hollow structure guides airflow and reduces near-ground wind speed by over 60%. Sand grains settle and accumulate in front of and between barriers. The design avoids excessive wind load that may overturn the barriers while achieving effective sand trapping and fixation, creating favorable conditions for subsequent vegetation restoration.

Advantages of HDPE Sand Barrier Panels
✅ Excellent UV Resistance and Weatherability Internally compounded UV stabilizers suit the intense solar radiation in northwest desert regions. The panels resist ageing and pulverization under long-term outdoor exposure.
✅ High Impact Resistance and Wear Resistance Superior toughness withstands repeated impact and abrasion by wind-blown sand with outstanding DIN abrasion performance.
✅ Salt-Alkali and Corrosion Resistance Free from corrosion and rust in saline-alkali Gobi conditions, ideal for saline desert environments.
✅ Lightweight and Easy Installation Lightweight panels enable manual handling and mounting, greatly cutting hoisting and construction costs, and adapting to undulating terrain.
✅ Permeable Design to Avoid Excessive Wind Load Scientific open area ratio prevents overturning caused by high wind pressure on solid barriers, balancing sand trapping and airflow permeability.
✅ Low Maintenance Requirements No annual replacement required to reduce long-term operation and maintenance costs. The material is recyclable and environmentally friendly.
Application Scenarios of HDPE High Vertical Sand Barriers
Transportation Projects Wind and sand protection on the windward side of desert railways and Gobi highways to prevent subgrade burial by drifting sand. Widely adopted in projects such as the Golmud–Korla Railway and Beijing–Xinjiang Expressway.
New Energy Bases Peripheral wind-sand protection for photovoltaic and wind power plants.
Desert Ecological Restoration Gobi and desert rehabilitation, restraining dune migration. Combined with straw checkerboard barriers to build an integrated sand control system featuring external sand blocking and internal sand stabilization.
Mining and Oil & Gas Bases Wind-sand protection for industrial sites; drifting sand interception around oases and villages.
