Guardrail Expanded Metal Mesh: Material & Construction
- Robust Material Options:
- Galvanized Steel (G90 Coating, ASTM A123): Corrosion-resistant for highway barriers or coastal infrastructure (strand thickness: 3–6 mm).
- Powder-Coated Carbon Steel: UV-resistant finishes (RAL color-matched) for urban guardrails or park safety fencing (ISO 12944 compliant).
- Aluminum Alloy 6061-T6: Lightweight yet durable (tensile strength: 290 MPa) for temporary construction barriers or bridge railings.
- Engineered Design Features:
- Diamond/Hexagonal Patterns: Standard apertures (50–150 mm spans) for impact absorption and visibility (EN 1317-2 crash-tested).
- Reinforced Edges: Rolled or welded borders to prevent fraying in high-traffic zones (OSHA 1910.23 compliant).
- Anti-Climb Design: Small apertures (≤76 mm) for prison perimeters or secure facility fencing.
Guardrail Expanded Metal Mesh: Performance Advantages
- Crash-Tested Safety:
- MASH TL-3/TL-4 Compliance: Absorbs ≥200 kJ impact energy for roadside barriers or bridge railings.
- High Tensile Strength (400–550 MPa): Resists deformation in vehicle collisions or heavy machinery zones.
- Durability in Harsh Conditions:
- Salt Spray Resistance (1,000+ hours, ASTM B117): Ideal for coastal highways or snow-prone regions with de-icing salts.
- Abrasion-Resistant Coatings: Epoxy or polyester finishes for mining site barriers or industrial walkways.
- Versatile Functionality:
- Visibility & Airflow: Open designs reduce wind load while maintaining driver sightlines on curved roads.
- Anti-Graffiti Surfaces: Smooth coatings for urban infrastructure or public transit systems.
Guardrail Expanded Metal Mesh: Precision Manufacturing & Testing
- Advanced Fabrication:
- Robotic Welding (AWS D1.1): Ensures seamless integration into modular barrier systems (panel sizes: 2–4 m lengths).
- Laser-Cut Mounting Holes: Precise alignment for quick installation on concrete posts or steel beams.
- Rigorous Quality Assurance:
- Load Testing (EN 1993-1-1): Validates ≥10 kN/m² vertical loads for pedestrian overpass railings.
- Crash Simulation (MASH Test Level 3): Certified for high-speed roadways (70–100 km/h impact scenarios).
- Coating Adhesion Tests (ASTM D3359): Cross-cut tape tests confirm ≥4B rating for long-term durability.
- Customization Options:
- Variable Mesh Density: Adjust aperture sizes for wildlife barriers (e.g., deer fencing) or construction site screens.
Guardrail Expanded Metal Mesh: Industry Applications
- Transportation Infrastructure:
- Highway Median Barriers: Galvanized steel mesh (4 mm strands, 100 mm apertures) with MASH TL-4 certification.
- Bridge Parapets: Powder-coated aluminum mesh (3 mm thickness) for corrosion-free edge protection.
- Industrial & Construction:
- Factory Floor Guardrails: Heavy-duty carbon steel mesh (6 mm strands) with anti-slip surfaces (R10 rating).
- Trench Shielding: Modular panels (2 m x 1 m) with quick-connect brackets for excavation site safety.
- Public Safety & Security:
- Stadium Crowd Control: Powder-coated barriers (1.2 m height) with anti-climb design (CPNI certified).
- Prison Perimeter Fencing: High-tensile steel mesh (5 mm strands, 50 mm apertures) with razor wire integration.
- Urban & Recreational:
- Bike Lane Separators: Aesthetically designed aluminum mesh (RAL 6018 finish) for city streets.
- Park Safety Railings: Green-coated steel mesh (76 mm apertures) blending with natural environments.
