ISO 17357 Certified Pneumatic Rubber Fender with Natural Rubber Cover and 50Kpa/80kpa Working Pressure

Our Pneumatic Rubber Fenders represent a reliable and versatile solution for modern marine fendering, delivering superior impact protection for vessels, port infrastructures, and offshore installations. Manufactured from high‑grade natural rubber and reinforced with multiple layers of high‑tensile synthetic cord, these fenders are engineered to absorb kinetic energy during berthing, minimising damage to both hulls and quay structures. Fully compliant with ISO 17357, they meet the highest international standards for safety, durability, and performance.

Each fender is constructed from premium natural rubber compounds, selected for their outstanding elasticity, abrasion resistance, and resilience against seawater, ozone, and UV exposure. The rubber cover is reinforced with multiple plies of nylon or polyester cord, providing exceptional burst strength and puncture resistance. Advanced vulcanisation and precision sealing technologies ensure superior air retention, enabling stable operation under repeated high‑compression loads and harsh tidal conditions. The outer surface is smooth and wear‑resistant, reducing friction during contact and prolonging the service life of both the fender and the vessel.

Our fenders are manufactured in strict accordance with ISO 17357, the international benchmark for marine fendering, ensuring full compliance with global performance and safety requirements. Each unit is designed for a working pressure of either 50 kPa or 80 kPa, providing optimal energy absorption and reaction force characteristics for various vessel sizes and berthing conditions. To guarantee reliability, every fender undergoes a rigorous air tightness test prior to deflation and packaging, confirming zero leakage and structural integrity. Furthermore, we offer optional third‑party inspections by leading classification societies, including BV, DNV, LR, ABS, and CCS, to satisfy specific project approval needs.

We provide three distinct configurations to accommodate different mooring environments and operational preferences:

• Sling Type – equipped with durable lifting slings for quick and effortless handling and installation.

• With Chain and Tire Net – features a protective chain and tire net covering, offering enhanced resistance to abrasion and mechanical damage in busy ports and terminals.

• Submarine Type – specifically designed for submerged or semi‑submerged applications, ideal for floating docks, offshore platforms, and tidal berths.

Understanding that each berth and vessel presents unique requirements, we offer extensive customisation to ensure perfect fit and performance. The fender’s diameter can be tailored from 0.5 m to 4.8 m, and the length from 1 m to 12 m, accommodating everything from small workboats to the largest VLCCs. The standard flange material is Q235 hot‑dip galvanised steel, providing excellent corrosion protection. For environments with higher corrosion risks, we can supply flanges in 304 or 316 stainless steel upon request. Additional customisation includes working pressure adjustments, colour options, and special fittings to match your exact specifications.

Each fender is fitted with safety valves at both ends, which automatically release excess internal pressure to prevent over‑inflation and potential rupture, ensuring safe operation under all conditions. The fender’s design achieves high energy absorption with low reaction force, effectively reducing peak impact loads on both the vessel and the dock structure. Its rapid compression and recovery characteristics allow it to adapt seamlessly to changing tidal levels and vessel approach angles, ensuring consistent protection throughout the berthing process.

Before shipment, every fender undergoes a comprehensive quality inspection process, including the mandatory air tightness test to verify that the internal pressure remains stable over a specified period. Only after passing this strict examination is the fender deflated, carefully folded, and securely packed for delivery. For projects requiring class certification, we coordinate with recognised societies to perform witnessed factory acceptance tests and provide full documentation, including material certificates, test records, and compliance statements.

We are confident in the durability and performance of our pneumatic rubber fenders, which is why we offer a 2‑year warranty against manufacturing defects. Our experienced technical support team provides installation guidance, maintenance advice, and responsive after‑sales service. Routine maintenance is straightforward – regular pressure checks and surface cleaning are sufficient to ensure long‑term reliability and cost‑effective operation.

Our pneumatic rubber fenders are extensively used in:

• Commercial ports, container terminals, and bulk cargo docks for ship‑to‑dock berthing.

• Ship‑to‑ship transfer operations, including lightering and STS cargo handling.

• Offshore platforms, floating production units, and temporary mooring buoys.

• Ferry terminals, yacht marinas, and inland waterway facilities.

• Harbour construction, salvage projects, and emergency fendering.
