Foam Filled Fenders
Hongruntong Marine Foam Fenders are foam-filled marine fenders engineered for superior energy absorption, long service life and minimal maintenance. Ideal for berth protection, ship-to-ship operations and offshore installations, our foam boat fenders offer reliable docking protection and excellent resistance to water ingress and abrasion.
Our foam-filled marine fenders combine a closed-cell foam core with a durable, weather-resistant outer skin to provide constant buoyancy and predictable impact performance. Designed for commercial ports, naval and offshore applications, these foam boat fenders minimize hull and pier damage while reducing lifecycle costs.
Key Features
-
Closed-cell foam core — prevents water ingress and maintains buoyancy.
-
