Core Engineering Advantages

1. Advanced Energy Absorption Technology
The cylindrical geometry of our fenders ensures 360° force distribution, minimizing localized stress during collisions. This design effectively reduces peak impact loads by up to 65%, safeguarding both vessels and docking structures from costly damage. Ideal for high-traffic ports or heavy-duty offshore platforms, our fenders excel in scenarios requiring consistent, large-scale energy dissipation.

2. Ultra-Durable Material Composition
Crafted from a proprietary blend of natural rubber, SBR (Styrene-Butadiene Rubber), and anti-oxidant additives, our fenders resist degradation from UV exposure, oil spills, and saltwater corrosion. Rigorously tested to perform in temperatures ranging from -45°C to +75°C, they maintain flexibility and structural integrity in Arctic cold or tropical heat.

3. Reinforced Anti-Twist Structure
Embedded high-tensile steel cables (optional) and layered rubber construction prevent deformation under torsional stress. This innovation ensures the fender retains its shape and energy absorption capacity even after years of repetitive impacts, reducing maintenance costs and downtime.

4. Customizable Solutions for Unique Challenges

Size Flexibility: Diameters from 200mm to 2000mm, lengths up to 6 meters.
Load-Specific Design: Tailored compression rates (30%–60%) and hardness levels (Shore A 50–75) to match vessel displacement and berthing velocity.
Modular Integration: Compatible with panel systems or floating pontoons for hybrid marine protection setups.

Applications Where Precision Matters

Our cylindrical fenders are engineered for scenarios demanding reliability and adaptability:

Ports & Terminals: Protect quay walls, lock gates, and container terminals from berthing collisions.
Offshore Energy: Shield oil rigs, LNG platforms, and floating storage units from vessel impacts.
Shipbuilding & Repair: Buffer docks during ship launches or dry-docking operations.
Coastal Infrastructure: Defend bridges, seawalls, and tidal barriers from storm surges and vessel strikes.

Why Hongruntong Marine Stands Apart

1. Globally Recognized Quality Assurance
Every cylindrical fender undergoes 3-stage quality control: raw material inspection, in-process stress testing, and final load certification. Compliant with ISO 17357, OCIMF, and PIANC guidelines, our products are approved by Lloyd’s Register, ClassNK, and Bureau Veritas.

2. End-to-End Technical Partnership

Simulation & Design: Leverage our R&D team’s expertise in Finite Element Analysis (FEA) to optimize fender layouts for your project.
On-Site Support: From installation guidance to lifecycle management, we ensure seamless integration with your infrastructure.
Sustainability Focus: Eco-friendly production processes and recyclable materials align with global ESG standards.

3. Competitive Edge for Clients

Rapid Production: Automated manufacturing lines enable lead times as short as 10–20 days for standard orders.
Cost Efficiency: Bulk order discounts and a 12-year limited warranty maximize ROI.
Global Logistics: Strategically located warehouses in Asia, Europe, and the Americas ensure timely delivery.
