Industrial Rubber Fender Superior Wear Resistance UV Stability And Minimal Maintenance

Industrial Rubber Fender Superior Wear Resistance UV Stability And Minimal Maintenance

Description

The D Type Fender from Hongruntong Marine is an advanced marine protection system designed for structures exposed to constant wave action, tidal changes, and vessel contact. It provides a reliable buffer between vessels and fixed installations such as bridge piers, floating docks, and offshore platforms, where both impact resistance and environmental durability are critical.

The fender’s distinctive D-shaped profile allows efficient energy absorption while maintaining structural stability. Its hollow core geometry balances elasticity and strength, offering consistent performance under compressive loads. Each fender is extruded from a specially engineered marine-grade rubber compound designed to resist ozone, UV, saltwater, and temperature fluctuations.

Case Study – Offshore Bridge Protection, Norway

A coastal bridge in western Norway faced frequent minor collisions from service boats and maintenance barges, especially during heavy tides and winter storms. The previous cylindrical fenders degraded rapidly, losing elasticity and tearing after two winters. Hongruntong Marine provided a customized cold-resistant D Type Fender using a low-temperature elastomer blend with enhanced tear resistance and anti-ozone additives.

Installed in 2020 along the pier faces, the D Type Fenders have since endured continuous exposure to freezing seawater, ice abrasion, and mechanical stress. After four years, inspection reports showed no structural damage, over 50% reduction in impact load on pier surfaces, and no performance loss even after temperatures below -25°C. The local marine authority recognized the system as a cost-effective, low-maintenance solution for coastal bridge protection.

This project demonstrated how Hongruntong’s D Type Fenders perform under extreme conditions—maintaining flexibility, adhesion, and shock absorption in harsh climates and corrosive marine environments.

Specifications

Features

Extreme Temperature Resistance
Engineered with advanced polymer blends that maintain elasticity and tensile strength from -40°C to +80°C. Ideal for northern climates or tropical offshore platforms with thermal cycling.

Enhanced Corrosion and UV Protection
The fender compound contains anti-aging agents, UV stabilizers, and anti-ozone components to resist sunlight, saltwater, and chemical degradation, ensuring long operational life even in exposed coastal environments.

Optimized Hollow Core Design for High Energy Absorption
The internal structure evenly distributes compression loads, providing superior impact energy absorption and quick recovery. This reduces stress transfer to bridge or platform structures.

Custom Mounting Flexibility
Adaptable to concrete, steel, or floating dock installations using various attachment systems—bolts, steel frames, or U-channel inserts. Modular design allows quick installation and replacement without extensive downtime.

Applications

Bridge Piers and Coastal Structures
Protects bridge columns from vessel collisions and reduces maintenance costs caused by repeated impacts and wave forces.

Floating Docks and Marine Platforms
Offers durable side protection for floating structures exposed to tidal and wave movement, maintaining consistent impact performance.

Oil Rigs and Offshore Installations
Provides critical hull-to-structure cushioning in offshore environments with high corrosion and dynamic loading conditions.

FAQ

1. Are D Type Fenders suitable for cold or icy waters?
Yes, our cold-resistant formulations remain flexible and impact-absorbing even at -40°C.

2. Can the fenders be used for underwater installation?
They can operate partially submerged; rubber compounds resist saltwater degradation and marine growth adhesion.

3. What mounting options are available for bridge applications?
We offer bolted steel plates, U-channel mounts, or reinforced brackets tailored to structural geometry.

4. Do the fenders require special coatings or painting?
No coating is required. The rubber itself contains anti-UV and anti-ozone stabilizers for surface protection.

5. How long is the expected lifespan in offshore environments?
Typically 10–15 years depending on wave exposure, vessel frequency, and maintenance practices.
