Composite Fenders
Hongruntong Marine manufactures composite fenders and D-section composite rubber fender systems. Professional composite fenders solutions for marine protection.

Hongruntong Marine specializes in manufacturing high-performance composite fender systems using advanced material technology. Our comprehensive composite fenders range includes innovative composite rubber fender products and specialized D section fender rubber solutions. These engineered D fender systems combine superior impact absorption with exceptional durability, providing reliable protection for ports, docks, and marine structures in the most challenging environmental conditions.
Characteristics
Advanced Composite Material Technology
Our composite fender utilizes engineered polymer compounds that provide excellent strength-to-weight ratio, outstanding impact resistance, and superior environmental durability compared to traditional rubber fenders.
Optimized D-Section Geometry
The D section fender rubber features precisely engineered profiles that ensure optimal stress distribution and maximum energy absorption during vessel berthing operations.
Corrosion-Free Performance
Unlike steel-reinforced fenders, our composite rubber fender systems are completely immune to corrosion, making them ideal for saltwater environments and significantly reducing maintenance requirements.
Enhanced Durability
All composite fenders in our product line demonstrate excellent resistance to UV radiation, extreme temperatures, and marine biological growth, ensuring long-term performance reliability.
Applications
Commercial port terminals and container berths
Oil and gas tanker facilities
Ferry terminals and Ro-Ro ramps
Navy and military installations
Shipyards and repair facilities
Offshore platforms and marine structures

Our Advantages as a Fender Manufacturer
As a factory-direct supplier, we offer end-to-end value that generic marine suppliers can’t match:
Customization for Unique Docks: We adjust the size (length, cross-section) and material blend of Composite Fender, Composite Rubber Fender, and D Section Fender Rubber to fit non-standard infrastructure—e.g., curved dock edges, extra-narrow berths. Custom orders take 3–4 weeks (no tooling fees) and include 3D design previews.
Cost-Effective Bulk Solutions: For bulk orders (50+ units) of Composite Fenders or D Fender, we offer 10–15% discounts. Our Composite Rubber Fender also cuts long-term costs by 30% vs. all-steel fenders (lower maintenance + longer service life).
Global Inventory & Fast Delivery: We stock standard Composite Fender, D Fender, and D Section Fender Rubber in 4 regional warehouses (Europe, Asia, North America, Australia). This ensures 3–5 day delivery for emergency repairs—critical for ports avoiding operational downtime.
On-Site Installation Support: We provide free installation guides (with 3D diagrams) for all fenders and offer on-site training for large orders. Our engineers also help calculate optimal fender spacing (e.g., 1.5m apart for D Fender) to eliminate protection gaps.
Quality Assurance & After-Sales Support
We maintain strict quality control to ensure reliability and long-term performance:
Third-Party Testing: All fenders undergo rigorous testing per ISO 18072 (marine fender standards)—including impact absorption, compression resistance, and 1000-hour salt-spray tests. Test reports are included with every order to verify compliance.
Tailored Warranties: Standard warranty is 12 months for D Fender and D Section Fender Rubber; Composite Fender and Composite Rubber Fender (for heavy use) get 18 months. We also offer a 5-year anti-corrosion guarantee for composite cores.
24/7 Technical Support: For post-purchase issues (e.g., rubber wear, installation alignment), our team responds within 2 hours. We ship replacement parts (like rubber sleeves for Composite Rubber Fender) within 48 hours to minimize downtime.
Frequently Asked Questions (FAQ)
Q: What are the advantages of composite fenders over traditional rubber fenders?
