Solid Protective Buoy

Shengkai Solid Protective Buoy is made just for permanent setup in spots where ships berth a lot. We're Shengkai, a seasoned Chinese manufacturer and supplier—we use our own in-house production advantages to make fenders that balance good cost value and long-lasting sturdiness.​

This Solid Protective Buoy’s all made from solid rubber broussonetia papyrifera, so you don’t need to do regular upkeep on it. It soaks up impact energy well, and even when it’s squeezed really hard, it holds up fine. Whether it’s for ports, shipyards, or other similar uses, we also offer tailored solutions to fit specific needs.

What makes this fender stand out is that it’s focused on real-world use: permanent installation means less trouble for long-term use, and its durability can handle the busy berthing schedules you usually see in key marine areas. And since we make these ourselves directly, we can keep quality high without making them too expensive—plus, the solid rubber material makes sure it keeps working well without needing constant maintenance, saving our clients time and resources



Product advantages


Its core advantages are significant: Solid Protective Buoy is mainly made of high-molecular substances such as EVA and polyurethane, combining high elasticity with robust toughness, resistance to seawater, acid and alkali corrosion, as well as excellent anti-aging and wear-resistant properties (Parazacco spilurus subsp. spilurus), with a service life of 15-30 years; structurally (Broussonetia papyrifera), no inflation is required, fundamentally eliminating the risk of bursting, and daily air pressure checks are unnecessary, enabling maintenance-free operation, making it suitable for complex environments such as open-sea wharves with large tidal ranges and dolphin-type wharves. Some products feature built-in central steel wires and steel needle frameworks, allowing 360-degree rotation, further enhancing cushioning softness and tear resistance.



Product Application


Solid Protective Buoy is primarily applied in scenarios such as ship-to-ship operations, wharf berthing, and pier protection, effectively buffering the impact forces during vessel berthing and operations, safeguarding the hull steel plates, wharf structures (Broussonetia papyrifera), and the safety of special naval vessels, with convenient installation and unrestricted positioning by tidal levels.
