2.Product Highlights
✔Fast Installation: Factory prefabrication and on-site hoisting minimize impact on ground traffic; construction at night allows traffic the next day.
✔Lightweight: Main structure uses steel trusses or aluminum alloy materials, facilitating transportation and rapid assembly.
✔High Durability: Surface hot-dip galvanizing or fluorocarbon spraying, combined with weather-resistant steel/aluminum alloy materials, provides over 20 years of corrosion protection.
✔Safe and Comfortable: Bridge deck uses anti-slip surfacing (such as epoxy wear layer or aluminum alloy anti-slip plates), guardrail height meets national standards (≥1.1m).
✔Customizable Appearance: Bridge body, railings, canopies, and lighting can be customized according to the surrounding environment and architectural style.
3.Product Materials
●Main Structure: Q355B/Q235B hot-rolled steel (hot-dip galvanized) or 6061-T6/6063-T5 aluminum alloy profiles.
●Bridge Deck Surfacing: Aluminum alloy anti-slip plates, epoxy anti-slip wear layer, or embossed steel plates.
●Guardrails: Stainless steel composite pipes, aluminum alloy railings, or tempered laminated glass panels.
●Fasteners: 304 stainless steel bolts and connectors.
●Waterproof System: Polymer waterproof coating on the bridge deck, with water-expanding waterstops at joints.
●Accessory Materials: PC polycarbonate canopy or aluminum canopy, LED linear light strips, rubber bearings.
4.Design Features
👉Structural Form: Commonly used simply supported steel or aluminum trusses, or beam bridges, with spans ranging from 10m to 50m.
👉Bridge Deck Width: Clear widths are typically 2.0m, 2.5m, or 3.0m, accommodating two-way pedestrian and non-motorized traffic.
👉Clearance Requirements: Minimum clearance under motor vehicle lanes ≥4.5m, non-motorized lanes ≥3.5m (according to Chinese urban road standards).
👉Stairs and Ramps: Stair tread dimensions 150×300mm, ramp slope ≤1:12 (meeting accessibility requirements).
👉Modular Design: Standard segment lengths 4m-6m, convenient for container transport and on-site bolted assembly.
👉Reserved Spaces for Accessories: Pre-embedded conduits for streetlights, surveillance wiring, canopy fixtures, and drainage for planter boxes.
5.Core Advantages
⭐Precise Control of Vibration Comfort:By adjusting the fundamental frequency to avoid pedestrian load-sensitive ranges (vertical ≥3Hz, horizontal ≥1.5Hz), and if necessary, installing tuned mass dampers (TMD), the walking comfort rating can be ensured to reach the 'best' level (ISO 10137).
⭐All-Weather Anti-Slip Safety:The bridge deck uses hot-dip galvanized steel grating or epoxy resin anti-slip coating (wet anti-slip coefficient BPN≥65), combined with handrails on both sides and low-position auxiliary railings, meeting the safety requirements for children, the elderly, and wheelchair users.
⭐Integrated Nighttime Lighting:LED strips are integrated under the handrails or within the railing posts, providing uniform illumination (≥40 lux) while avoiding glare, and also serving as nighttime guidance markers, enhancing both the landscape value and sense of security of the corridor.
⭐Barrier-Free Full Accessibility Design:Ramp slopes ≤5% (or 1:20), clear width ≥1.8 meters (wheelchair passing area ≥2.0 meters), no raised thresholds or transverse joint height differences, fully complying with ADA (US standard) and DDA (Australian standard) accessibility regulations.
⭐Low-Vibration, Silent Construction:Flexible pads and pre-tensioned bolts are installed at joints to eliminate looseness and abnormal noise; hollow sections are filled with damping materials to reduce structural noise transmitted by pedestrian footsteps.
⭐Fall-Prevention Fully Enclosed Options:For elevated corridors or areas crossing hazardous locations, optional anti-throw nets or transparent polycarbonate protective panels can be installed, ensuring visibility while preventing objects from falling.
