At Qingdao Sunkai Marine Supplies Co., Ltd., we have spent years focusing on one simple goal: making marine fenders that truly protect ships and port facilities in real operating conditions.
Marine fenders are often overlooked, but in practice they are the first and most critical safeguard during berthing, ship-to-ship operations, and offshore activities. Every impact absorbed correctly means less damage to hulls, terminals, and structures—and fewer operational risks for our customers. This understanding has guided our work from the very beginning.
Today, our marine fender products are widely used by ports and shipyards across China and are also supplied to customers in Southeast Asia, Europe, the Middle East, and South America. Through consistent product performance and dependable service, Qingdao Sunkai Marine Supplies Co., Ltd. has gradually earned long-term trust in both domestic and overseas markets.
From product development to manufacturing, we follow a clear principle: practical performance comes before complexity. Instead of pursuing unnecessary technical stacking, we focus on materials, structure, and durability—factors that directly determine how a marine fender performs after years of repeated impacts.
Our product range includes foam-filled fenders, rubber fenders, and inflatable (pneumatic) fenders, allowing us to meet protection requirements for a wide variety of scenarios. These include vessels ranging from small yachts and workboats to 1,000-ton cargo ships and 100,000-ton class vessels, as well as applications such as port terminals, offshore platforms, ship-to-ship transfer, and salvage operations.
Each fender type is developed to solve a specific problem rather than to simply expand a product list.
Our foam-filled fenders use a closed-cell polyurethane foam core combined with a polyurea protective outer layer. This structure allows the fender to absorb impact energy efficiently while maintaining stability even under heavy compression. In daily operations, this means lower reaction force on ships and port structures, and more consistent protection during frequent berthing.
Our rubber fenders are manufactured using carefully formulated blends of natural and synthetic rubber. They offer strong resistance to seawater corrosion and UV exposure, and they remain stable in temperatures ranging from -30°C to 80°C. In normal port conditions, their service life typically reaches 10 to 15 years.
Our inflatable fenders rely on air-pressure buffering to absorb energy. They are flexible, easy to deploy, and convenient to transport after deflation, making them especially suitable for ship-to-ship operations and temporary protection needs.
At Qingdao Sunkai Marine Supplies Co., Ltd., quality control is not treated as a final inspection step—it is integrated into the entire production process.
All of our marine fenders comply with ISO international standards and have passed inspections by recognized classification societies such as CCS and BV. From raw material testing to finished product delivery, every step is traceable and measurable:
Rubber materials are tested for wear resistance and tear strength
Foam cores are controlled for closed-cell rate and elastic recovery
Finished fenders undergo impact testing that simulates harsh marine conditions
Through this process, we consistently maintain a product qualification rate above 99.8%.
The true value of marine fenders is proven on site. Over the years, our products have delivered clear results:
A large domestic container terminal reduced structural damage by 40% after installing our rubber fenders, saving nearly RMB 2 million per year in maintenance costs.
A port in Southeast Asia has used our foam-filled fenders for five consecutive years under high-frequency berthing operations without failure.
Offshore platforms in the Middle East selected our customized inflatable fenders, which successfully protected facilities during severe storm conditions and high collision-risk operations.
These projects are not exceptions—they reflect how our products perform when conditions are demanding.
Every port and vessel operates under different conditions. For this reason, we place strong emphasis on customized fender solutions. Our technical team designs fender size, structure, and installation methods based on factors such as ship tonnage, berthing speed, tidal range, and terminal structure.
We also support specialized requirements, including oil-resistant fenders for oil terminals, optimized floating systems for large tidal variations, and modular fender designs for offshore wind power platforms.
To support customers worldwide, we have built a responsive global service system, offering technical consultation, installation guidance, and after-sales support. Today, our marine fenders are exported to more than 30 countries and regions, with a repeat order rate of 72%, reflecting long-term customer confidence.
Looking ahead, Qingdao Sunkai Marine Supplies Co., Ltd. will continue to refine the core performance of our marine fenders. We will further improve material formulations, structural durability, and cost efficiency, while expanding into emerging applications such as polar ports and deep-sea platforms.
Our goal remains unchanged: to provide reliable, practical protection solutions that help make marine operations safer and more efficient worldwide.
