Engineered with High Molecular Density Polyethylene to Deliver Superior Buoyancy and Global Certifications.
Established in 2019, an industrial pioneer based in Huangyan, Taizhou, Zhejiang—the manufacturing heartland of high-precision plastics technology in China.
Over the years, we have scaled our operations to serve international maritime projects, commercial ports, and custom docking providers globally. Our core competency lies in the advanced application of heavy-industry blow molding processes. We design, prototype, and manufacture custom polymer flotation cubes, single and dual Jet Ski platforms, and various blow-molded industrial parts designed to endure complex environmental stressors.
By strictly enforcing the ISO 9001 quality management framework and sourcing only premium virgin High-Density Polyethylene (HDPE), we guarantee that every modular block exported features structural stability, high tensile resistance, and superior UV protection.
High load thresholds, structural flexibility, and superior polymer density for heavy-duty commercial applications.
"The modular structure of our OEM Dual Jet Ski Floating Docks distributes localized pressure dynamically across the connected pontoon grid, allowing marine operators to park multiple PWCs side-by-side without risking tilt, structural degradation, or material stress points."
The Evolution of Marine Polymer Engineering & Next-Generation Dry Dock Solutions
Our current development roadmap focuses on incorporating advanced anti-UV compound variants and anti-static additives directly during the extrusion blow molding phase. This prevents color degradation, cracking, and chalking in extreme UV zones such as the Middle East and tropical coastlines.
By refining the inner rib architectures within each float module, our engineering team has minimized empty weight while retaining superior compressive strength. Future iterations will utilize finite element analysis (FEA) to maximize impact resilience when PWCs are docked at high speeds.
To optimize assembly time for commercial marinas, we are introducing a patented modular connecting pin that features dual-locking threads. This guarantees that side-by-side configurations remain flush, eliminating water pooling between the seams and enhancing walking safety.
Meeting Global Infrastructure Demands for Municipal and Commercial Projects.
Modern coastal planning requires eco-friendly marine equipment that integrates seamlessly into delicate ecosystems without causing pollution. Traditional concrete and treated wood docks decompose and release toxins over time. Our blow-molded HDPE modular pontoons offer a sustainable alternative, providing high structural durability, chemical inertness, and stability in changing environments.
For operations hosting personal watercraft fleets—such as resort rentals, police patrols, and rescue services—the dual Jet Ski floating dock offers a compact footprint with high load distribution. The system operates efficiently in changing tides, floating dynamically to keep vessels clear of underwater rocks and debris.
Leveraging Taizhou's High-Scale Industrial Plastics Ecosystem to Deliver Cost-Efficiency
Our facility in Huangyan utilizes automated blow molding production lines. This level of automation minimizes human error, decreases cycle times, and ensures structural consistency across large production batches. By automating the control of extrusion heat profiles and parison thickness, we produce products that maintain consistent wall thickness across all corners, which is critical for pressurized structures like marine pontoons.
Taizhou’s established petrochemical and plastics manufacturing ecosystem gives us direct, high-volume access to premium raw materials. This proximity reduces transit times and buffers our production against global supply chain disruptions, allowing us to maintain predictable lead times for international shipping and large-scale commercial project developments.

Direct technical answers from Shenghuang Factory engineers on floating dock performance, logistics, and assembly.
The system's modular, flexible structure distributes wave energy dynamically, reducing risk compared to rigid docks. In high-wind areas, the performance depends heavily on utilizing robust, heavy-duty piling brackets and elastic anchoring setups. Reports from our global clients indicate excellent results during severe weather events.
Yes. If there is no local distributor in your area, we ship products directly from our Huangyan factory to your nearest international container freight terminal, providing complete customs documentation and import documentation support.
Absolutely. The dock is engineered to withstand freezing conditions and ice exposure. The tapered sides of our modular cubes cause the system to slide upward when ice expands, riding on top of the sheet rather than being crushed by it.
The primary consideration during winter freeze-up is ice movement. In areas with static ice, the dock can remain in the water safely. However, if there are heavy currents or moving ice blocks that could shear the anchoring lines, the dock should be disassembled and stored on land before the spring thaw.
For safe walking and stability, we recommend a minimum platform width of three modular cubes (approx. 1.5 meters). This width balances buoyancy and load distribution to prevent tilting under foot traffic.
Yes. The modular cubes draw only 5 to 10 cm of water when unloaded. However, ensure that the launch end of the dock has sufficient water depth to allow the Jet Ski hull to slide off safely without bottoming out.
Our manufacturing facility was established in 2019. Over the years, we have grown into a major supplier of modular HDPE products in China, serving commercial and industrial clients globally.
Our OEM Dual Jet Ski docks are made from virgin HDPE mixed with anti-UV stabilizers. They are designed to last over 15 years, even when exposed to harsh sunlight, salt water, and marine organisms, without requiring paint or structural treatments.
