These versatile cylindrical fender products combine robust construction with optimal performance, making them ideal for various vessel types and docking configurations.
Hongruntong Marine cylindrical marine fenders (also called cylinder fenders or cylindrical boat bow fenders) are robust rubber/foam-core impact absorbers designed to protect hulls, quay walls and offshore equipment during berthing and mooring. Engineered for long service life and predictable energy absorption, these cylindrical fenders are ideal for workboats, tugs, barges and small to medium vessels that require dependable bow protection and side-lining contact points.
Key features & benefits
Proven cylindrical profile — distributes contact forces uniformly for steady, predictable compression and rebound.
Benefit: reduces shock loads to hull structure and minimizes point damage.
Durable outer skin — abrasion-resistant and UV stable.
Benefit: longer life in harsh marine environments; lower replacement costs.
High-energy absorption core (closed-cell foam or reinforced rubber) — excellent compression recovery.
Benefit: protects vessel and infrastructure under repeated impact.
Multiple mounting options (through-bolt, chain/rope wrap, bracket attachments) — flexible installation.
Benefit: easy retrofit to existing bow or fendering arrangements.
Wide size range & custom lengths — from small boat bow fenders to large vessel bumpers.
Benefit: one supplier for varied fleet requirements; easier inventory management.
Low maintenance design — simple cleaning, inspection and occasional surface treatment.
Benefit: reduces downtime and operational cost.
Typical Applications
Bow protection for tugs, pilot boats and workboats (cylindrical boat bow fender).
Side protection for barges and pontoons.
Quay, jetty and small pier fendering systems.
Temporary or permanent fendering on construction or offshore work sites.
Ship-to-ship transfer protection for small/medium vessels.
