Marine Rubber Fender High Impact Resistance Seawater Corrosion Resistance
Description
Dock Rubber Fender is a critical marine protection system designed to absorb berthing energy and prevent structural damage to vessels and quay walls. Hongruntong Marine’s heavy-duty dock rubber fenders are manufactured from high-grade natural rubber compounds with optimized elasticity and abrasion resistance. Available in multiple profiles and dimensions, these fenders are engineered to withstand repeated high-impact loads while maintaining stable performance in harsh marine environments.
The product demonstrates excellent load-bearing capacity, superior energy absorption efficiency, and long service life under continuous compression. Its weather-resistant formulation ensures reliable operation in extreme temperatures, UV exposure, and saline conditions. Dock rubber fenders are widely applied in commercial ports, container terminals, and shipyards, providing safe, efficient, and cost-effective berthing solutions.
Case Study – Container Terminal Berthing Upgrade
A large container terminal in Southeast Asia handling 50,000–80,000 DWT container vessels experienced frequent quay wall damage due to increased vessel size. Hongruntong Marine supplied customized dock rubber fenders designed for high reaction force control. After installation, vessel berthing safety improved significantly, maintenance costs dropped by over 30%, and port operations achieved higher berthing efficiency. Terminal operators reported stable long-term performance with minimal wear after two years of continuous use.
