Road Protection Special Net

I. Product Overview:

Roads, as critical carriers for traffic, face safety hazards such as vehicles losing control and crashing, pedestrians crossing recklessly, debris intrusion, and slope collapses. This specialized road protection chain-link mesh is designed specifically to address these pain points. It is woven from high-strength metal wires and can be customized according to road types (highway, municipal, rural roads) and protection scenarios (central median, slope, roadside). It features impact resistance, anti-climbing, weather and corrosion resistance, and easy installation, complying with the "Highway Traffic Safety Facility Design Specifications" to ensure the safety of vehicles and pedestrians.

II. Core Advantages:

Addressing the characteristics of road protection—"high traffic volume, fast speeds (highway 120 km/h, municipal 60 km/h), complex environments (exposure to sun, rain, snow, and ice impact), and diverse terrain (flat ground, slopes, curves)"—this product highlights its fundamental differences from ordinary protective nets:

1. Impact Resistance and Intrusion Prevention, Strengthening Road Safety

• Material and Strength Design:
  • Uses Q355 high-strength low-alloy steel wire (or hot-dip galvanized steel wire) with a wire diameter of 3.5-6.0 mm (5.0-6.0 mm for highways, 4.0-5.0 mm for municipal roads, 3.5-4.0 mm for rural roads). Tensile strength ≥600 MPa, mesh impact resistance ≥10 kN/m². Can withstand side scrapes from small vehicles (speed ≤30 km/h), pedestrian collisions, and falling rock impacts (weight ≤50 kg). The mesh only deforms slightly without breaking, effectively preventing vehicles from running off the road or pedestrians crossing recklessly.
• Targeted Protection Design:
  • Mesh Size Adaptation: 5 cm × 10 cm for central medians (anti-glare, anti-debris scattering), 5 cm × 5 cm for roadside protection (anti-climbing), 8 cm × 12 cm for slope protection (balancing water permeability and soil stabilization). The mesh is uniform and burr-free to avoid snagging vehicles or pedestrians' clothing.
  • Height Customization: 1.2-1.8 m for roadside protection (preventing pedestrians from climbing over), 1.5-2.0 m for central medians (blocking direct headlight glare), 2.0-3.0 m for slope protection (preventing soil collapse onto the road). The gap between the bottom and the ground is ≤5 cm (preventing small animals from entering).

2. Weather and Corrosion Resistance, Adapting to All-Climate Road Environments

• Surface Treatment Process:
  • Hot-Dip Galvanizing (zinc coating thickness ≥100 μm, salt spray test resistance ≥800 hours): Suitable for roads in dry areas, resisting rain and dust erosion. Service life of 10-15 years with low maintenance costs.
  • Hot-Dip Galvanizing + Powder Coating (color options: green, gray, blue, matching road landscapes): Dual protection with zinc and plastic layers, salt spray test resistance ≥1200 hours. Resists salt spray in coastal areas and erosion from de-icing agents (containing salt) in northern regions. Service life of 15-20 years, especially suitable for highways and coastal roads.
• Extreme Environment Adaptation:
  • Low-temperature areas (-30°C): The mesh material does not become brittle and can withstand snow and ice accumulation (snow depth ≤30 cm). High-temperature areas (60°C): The powder coating does not peel or fade, with excellent UV aging resistance and no cracking under long-term exposure.

3. Conforming to Road Terrain, Adapting to Complex Scenarios

• Flexibility and Adaptability:
  • The chain-link mesh has an elongation rate ≥20%, allowing it to bend flexibly along road curves (e.g., bends, ramps) with a conformity rate ≥95%. No cutting or splicing is needed, avoiding protection gaps (traditional welded nets often form right-angle gaps at curves).
  • For slope protection, it can be laid along slopes (≤60°) with close contact to the soil. Fixed with anchor rods (4-6 per square meter), it stabilizes soil to prevent collapse while allowing rainwater penetration (permeability ≥90%), avoiding water accumulation and landslides.
• Easy Installation:
  Comes with "road-specific fasteners" (including expansion bolts, U-clamps, flange plates) for precise connection to concrete barriers, corrugated beam guardrails, and soil shoulders. Installation efficiency is 30% higher than traditional guardrail nets, reducing road closure time during construction.

4. Balancing Transparency and Safety, Without Obstructing Driving Visibility

• Visual-Friendly Design:
  The mesh has a light transmittance ≥70%, not blocking drivers' sightlines (especially at curves and intersections), avoiding traffic accidents caused by obscured views. The matte surface treatment prevents strong reflection of headlights at night, ensuring safety for oncoming traffic and improving road traffic efficiency.

III. Technical Parameters:

IV. Applicable Scenarios:

• Core Scenarios:
  • Highways: Central medians (anti-glare, anti-crossing), roadside protection (preventing vehicle intrusion), interchange slopes (preventing collapse).
  • Municipal Roads: Separation of sidewalks and roadways, bus lane barriers, areas near schools/hospitals (preventing pedestrian jaywalking).
  • Rural Roads: Protection at widened narrow sections, roads near water or cliffs (preventing vehicles from falling), village entrances (restricting large vehicle entry).
  • Scenic Area Roads: Roadside in mountainous scenic areas (preventing falling rocks), lakeside roads (blending with natural landscapes, green powder coating for aesthetics).

V. Service Support:

• Customized Solutions: Based on road design drawings (barrier type, curve radius) and regional conditions (climate, corrosion level), free customized recommendations for material, mesh size, and height are provided, along with CAD installation diagrams (including bend angle design for curves).
• Compliance Support: Full set of test reports (impact resistance, salt spray resistance, tensile strength) provided, complying with JT/T 1074-2016 "Highway Guardrail Net" standards, assisting with acceptance by supervision units and transportation departments.
• Supply Chain and After-Sales:
  • Standard specifications shipped within 7 days; bulk orders (≥1000 m²) enjoy exclusive discounts for road projects. Supports "sample testing first (1 m² sample), order after approval".
  • 5-year warranty (free replacement for non-human damage), lifelong technical consultation (e.g., maintenance in snowy conditions, partial replacement solutions).
