What are bridge fenders？

NANHAI is a trusted manufacturer and solution provider specializing in bridge fender systems and marine protection equipment. With years of experience serving global infrastructure and port projects, we understand how to help engineers and decision-makers protect bridges and waterway structures effectively.

In this article, we explain what bridge fenders are, how they work, and why they’re essential for safe and compliant bridge design, especially for professionals involved in ports, highways, and civil construction.

What Is a Bridge Fender?

A bridge fender is a structure installed around bridge piers or towers. It absorbs the impact energy when a ship accidentally hits the bridge, reducing the risk of damage.

At NANHAI, we design fender systems that:

• Reduce the impact forces from vessels
• Protect bridge piers and structures
• Improve safety in marine traffic areas
• Comply with international anti-collision standards

Types of Bridge Fenders – NANHAI Product Range

At NANHAI, we offer various bridge collision protection systems for different waterway and structural needs:

1. Attached Fenders

Fixed directly to bridge piers:

• Steel-frame fenders
• Rubber fenders (solid or cell type)
• Composite fenders
• Timber fenders

Best for low to moderate traffic waterways.

2. Independent Fender Structures

Standalone protection built near the bridge:

• Reinforced concrete barriers
• Steel-pile structures with energy-dissipating layers
• Ideal for large bridges and busy ports

3. Floating Fender Systems

Using pneumatic or foam-filled fenders:

• Easy to install and maintain
• Effective in tidal or deep water zones

All fender types are customizable at NANHAI based on your technical and environmental needs.

Compliance with International Safety Standards

NANHAI’s bridge fender systems meet or exceed key standards, including:

• China’s JTG/T3360-02-2020
• Port and Maritime regulations
• Environmental impact and risk safety requirements

We also provide third-party inspection reports and design support documentation to meet your approval and tender needs.

Installation and Maintenance – NANHAI Support Services

NANHAI provides full support from design to installation:

• Pre-design consultation and energy absorption calculation
• On-site guidance during installation
• Technical training and inspection support
• Annual inspection plans are available

With proper care, NANHAI fenders last 5 to 15 years, depending on use and environment.

Cost vs Value – Why NANHAI Fenders Save You More

Though initial costs may seem high, fenders greatly reduce future repair and liability costs.

💡 Case: One of our clients in Southern China installed NANHAI rubber fenders on a river-crossing bridge. Afterward, minor collisions caused no structural damage, saving over 2 million RMB annually in repair and downtime.
