Self-floating Steel-clad Composite Bridge Anti-collision Facility
Safety,Stability and Economy are Our Core Product Power
Self-floating steel-clad composite bridge collision protection facility is a new anti-collision system developed by NANHAI on the basis of traditional bridge collision protection equipment. Installed around bridge piers, it can float up and down along the pier axis by its own buoyancy according to changes in water level, always maintaining the optimal collision protection height.
New Bridge Protection for Complex Waterways
In navigation operations, operational errors, extreme weather and complex currents often cause ship collisions, threatening bridge and ship structures.
As cross-river and cross-sea projects expand, traditional anti-collision facilities show limitations due to heavy weight, easy corrosion and insufficient buffering.
The self-floating steel-clad composite bridge anti-collision facility is designed for complex hydrology and high-intensity navigation to reduce collision hazards to bridge structures.
Main configurations include: rectangular, semi‑circular, circular, profiled, polygonal, etc.
We also provide composite anti‑collision facilities with energy absorption ratings of 100t, 500t, 1000t and 3000t.
Available in a wide range of customizable colors.
Core Structure
01 Steel-Clad Outer Shell
FRP composite shell with UV absorbers and anti-aging agents for long-term corrosion resistance and weatherability.
02 Energy Absorption Core
Filled with energy-dissipating lattice webs, steel plates, and closed-cell foam to absorb kinetic energy via friction and compression.
03 Damping System
Inner rubber damping elements and PE wear-resistant panels provide primary-level energy absorption to prevent daily fatigue impacts.

Five Core Product Advantages
Superior Energy Absorption (Bridge & Vessel Protection)
Flexible materials combined with internal fillers can reduce impact force by over 60%, minimizing vessel damage to the greatest extent.
Lightweight & Convenient
Independent units are lightweight, resulting in low transportation and hoisting costs, and effectively ensuring the safety of bridge structures.
Exceptional Weather Resistance
Resistant to acids, alkalis, and salt spray, maintaining stable performance under tidal changes and harsh hydrological environments.
Active Guidance
The rounded corner structure can deflect the bow, preventing the vessel from continuing to impact the pier and actively reducing collision energy.
Customizable Appearance
The exterior can be customized with eye-catching colors or reflective coatings, significantly improving visual safety for nighttime navigation.
Successful Cases
A collection of bridge anti-collision engineering practices, demonstrating the mature application and reliable performance of self-floating anti-collision facilities in various water areas and working conditions.
In 2025, an overseas company approached NANHAI for a bridge protection project.
The self-floating steel-clad composite bridge anti-collision facilities developed and manufactured by NANHAI stood out among many competitors for their outstanding safety, stability and high adaptability, and won the bid successfully.

Frequently Asked Questions (FAQ)
1Is the product design compliant with current national standards?
Yes, fully compliant.
Our product design and R&D strictly followJTG/T 3360-02-2020 Specifications for Collision Design of Highway Bridges.
2How does the facility avoid displacement in fast-flowing water?
It is equipped with a professional connection mechanism and an internal damping system.The streamlined bottom design effectively reduces water resistance, ensuring structural stability even in high-flow conditions.
3How does the product meet anti-collision requirements under large water level fluctuations, such as in reservoir areas or tidal zones?
Our product adopts a self-floating design.
It features a streamlined floating body structure at the bottom, filled with high-density closed-cell foam, ensuring it floats up and down with the water level at all times.The protection zone always covers the water surface where ships are most likely to collide.
