Marine Roller Fenders
Hongruntong Marine manufactures roller fenders including boat roller fender and dock roller fender systems. Professional roller fenders marine solutions with smooth rolling operation.

The roller fender is a specialized marine fender designed to guide and protect vessels during berthing and docking. Unlike traditional static fenders, the roller fender rotates to absorb impact while reducing friction, making it highly effective in preventing hull damage. Whether applied as a boat roller fender, dock roller fender, or in heavy-duty roller fenders marine applications, this solution is ideal for areas where vessels must enter or exit at sharp angles.
Manufactured with durable rubber and high-strength steel components, rolling boat fenders are commonly installed on quay walls, piers, and lock entries to provide safe berthing. Their rotating design not only minimizes stress on vessels but also ensures smoother operations in ports and harbors.
Characteristics
Smooth Rolling Mechanism
The roller fenders feature precision-engineered rollers that rotate freely upon contact, significantly reducing friction between vessels and structures while providing consistent protection.
Vessel-Specific Protection
Our boat roller fender systems are specifically designed for vessel installation, offering excellent impact absorption and hull protection during docking maneuvers.
Dock Integration Design
The dock roller fender products incorporate heavy-duty construction and corrosion-resistant materials, ensuring long-term reliability in challenging port environments.
Marine-Grade Durability
All roller fenders marine solutions are manufactured with premium materials that withstand saltwater exposure, UV radiation, and continuous heavy-duty use.
Applicantions
Port Entrances & Lock Gates – Smooth vessel entry and exit at narrow or angled approaches.
Dock & Pier Protection – Ensures safe berthing for commercial and naval ships.
Boat Berthing – Reliable protection for yachts, ferries, and fishing vessels.
Heavy-Duty Marine Operations – Suitable for terminals handling bulk carriers, tankers, and Ro-Ro ships.
