Highway Safety Fence, Highway Sound Barrier Fence Panels, W Beam Highway Guard Rail

Highway safety fencing is an essential component in road infrastructure . These fences are specifically engineered to withstand the forces exerted by vehicles, preventing accidents, reducing impact damage, and mitigating risks in critical areas such as intersections, bridges, and along busy highways. The two main types of highway safety fences are Highway Sound Barrier Fence Panels and W Beam Highway Guard Rails.

Highway Acoustic Sound Barrier Fence Panels

Sound barrier fence panels are commonly used along highways that pass through residential areas, near schools, and in other locations where noise control is a priority.

Typical Dimensions and Specifications:

• Height: 2.0 m – 6.0 m
• Length: 2.0 m – 5.0 m
• Panel Thickness: 2 mm – 6 mm
• Weight: 20 – 50 kg per square meter
• Sound Transmission Class (STC): 28 – 45 DB
• Noise Reduction Coefficient (NRC): 0.60 – 0.95
• Post Spacing: 2.5 m – 3.5 m
• Wind Resistance: Up to 160 km/h
• Corrosion Resistance: 15 – 50 years (depending on coating and exposure)

Material Composition

• Steel Grade: Galvanized Steel (G90, G120 coating) for corrosion resistance.
• Coating/Finish: Hot-dip galvanization for superior corrosion resistance, powder coating (Polyester, Epoxy) in various colors for enhanced aesthetics and UV resistance.
• Sound Absorption Layer: Acoustic Insulation Materials (acoustic foam perforated steel with soundproofing backing).
  Thickness of insulation: 50 mm – 100 mm.
• Surface Finish: Smooth, perforated, or embossed surface options, perforated panels designed for better sound absorption.

Mesh Fence Panel Dimensions

• Panel Height: 2.0 m – 6.0 m, Custom heights can be manufactured for specific project needs.
• Panel Length: 2.0 m – 5.0 m (commonly used for continuous fence sections). longer panels reduce the number of joints and installation time, making them more efficient.
• Panel Thickness: Typically 2 mm – 6 mm (for steel sheets), insulation layer thickness 50 mm – 100 mm ( soundproofing materials are included).
• Weight: Steel panels typically weigh between 20 – 50 kg per square meter, depending on thickness and material used.

Sound Transmission Class (STC)

• Typical STC rating for highway sound barrier steel panels ranges from 28 to 45 dB depending on design.
• Panels with acoustic insulation or perforation usually offer higher STC ratings, providing better noise reduction.

Noise Reduction Coefficient (NRC)

• Standard NRC rating for steel sound barriers: 0.60 – 0.95.
• Higher NRC values (above 0.85) indicate better sound absorption for areas with higher traffic noise levels.

Steel Fence Post and Mounting System

• Steel Posts: Typically H-beam or round posts, galvanized for corrosion resistance.
• Post Height: 2.5 m – 6.0 m (based on panel height).
• Post Diameter/Dimensions: 120 mm – 200 mm for round posts; 100 mm x 100 mm to 200 mm x 200 mm for H-beams.
• Post Spacing: Usually 2.5 m – 3.5 m apart, depending on panel size and wind load considerations.
• Post Material: Galvanized steel or stainless steel for longevity and strength.
• Panel Fixing: Panels are fixed to posts using brackets or direct bolting systems.
• Wind Load Resistance: Panels are designed to withstand wind speeds of up to 120 km/h – 160 km/h depending on panel type and height.
• Corrosion Resistance: Hot-dip galvanized steel offers 15 – 50 years of service life, depending on exposure to environmental conditions (coastal or urban environments may see shorter lifespans).
  Stainless steel panels offer 50 years or more of corrosion resistance.
• Standard Color Options: Common colors include gray, black, blue, green, beige, or white, with custom color options available. Perforated designs allow for more light and air flow, while also enhancing aesthetic appeal.
• Custom Designs: Steel panels can be customized with decorative patterns, logos, or graphics. Embossed patterns for artistic applications.

W Beam Highway Guard Rail

The W Beam guard rail is one of the most widely used safety barriers, featuring a "W" shaped beam that is mounted on posts. It is designed to absorb and redirect the energy of a vehicle impact, preventing vehicles from crossing over or hitting roadside objects. W Beam guard rails are used along the edges of highways, around sharp curves, bridges, and areas with high traffic volumes. They are ideal for locations requiring high durability and impact resistance.

• Material: Hot-dip Galvanized Steel, Steel Alloy
• Beam Width: 300 mm – 400 mm
• Beam Thickness: 2.5 mm – 4.0 mm
• Post Height: 1.8 m – 2.0 m
• Post Diameter/Dimensions: Round: 140 mm – 200 mm, Square: 120 mm x 120 mm, H-Beam: 100 mm x 100 mm – 200 mm x 200 mm
• Post Spacing: 2.5 m – 4.0 m
• Panel Length:4.0 m – 4.5 m
• Height of Barrier: 0.8 m – 1.0 m
• Weight (per meter): 25 kg – 35 kg (depending on material and thickness)
• Wind Load Resistance: Up to 110 km/h – 120 km/h (depending on post spacing and material)
• Crashworthiness: Meets MASH or NCHRP 350 standards
• Corrosion Resistance: 15 – 25 years (Galvanized), 50+ years (Stainless Steel)
• Reflective Tape Optional for increased visibility
