The company aims to lead the industry in both product quality and sustainability, positioning itself as a trusted partner for clients in various industries globally.
At Shenghuang, our engineering team continuously pushes the limits of high-molecular-weight High-Density Polyethylene (HMW-HDPE). The structural durability of our modular plastic jetski docks relies heavily on our specialized raw material formulations and precision extrusion blow molding parameters.
Marine environments subject plastics to intense UV exposure, temperature fluctuations, and saltwater corrosion. To combat these forces, we integrate advanced UV stabilizers (UV-8 level and above) and hindered amine light stabilizers (HALS) into our virgin HDPE compound. This ensures our floating pontoon modules resist degradation, embrittlement, and discoloration for over 10 years, even under intense tropical sunlight.
One of the critical technical challenges in blow-molded floating cubes is avoiding structural weak spots at the corners. Our modern machines feature multi-point parison programming. This allows our manufacturing lines to dynamically control the wall thickness of the molten plastic tube during extrusion. By allocating more material to high-stress areas (such as the interlocking tabs and load-bearing corner edges), we achieve uniform wall thickness (up to 8-10mm at structural intersections), ensuring exceptional drop resistance and load capacity.
Our research department is currently working on three primary milestones:
How modular HDPE structures solve complex water-access challenges in diverse global industries.
Our drive-on jetski docks permit rapid docking, eliminating hull scratches and reducing customer turnaround times. The anti-slip patterns ensure guest safety while boarding.
Used as floating walkways, working platforms, and aquaculture feed stations. The chemically inert nature of our HDPE avoids chemical leaching, preserving delicate aquatic biomes.
Modular configurations can quickly adapt to emergency platforms, floating bridges, or public parks. They are highly resilient to dynamic forces and rapid currents.
Based in Huangyan, Taizhou—China's mold capital—Shenghuang capitalizes on unmatched proximity to advanced tooling workshops and raw material supply networks. Our factory has digitalized its manufacturing execution systems (MES) to coordinate everything from material compounding to final product dispatch.
This localized cluster allows us to build prototype molds in a fraction of the standard industry time, permitting agile OEM customization for global clients. With automated robotic arms taking charge of parison control and automated trimming, we reduce manual assembly defects, enhance cosmetic consistency, and keep manufacturing overheads lean.
“Through automated quality control, we maintain a defect rate below 0.05% across large-scale container production orders.”
Precision robotic arms handle excessive plastic trimming automatically, ensuring clean seams.
Direct supply pipelines of premium petrochemical polymers ensure raw material consistency.
Minimizing physical handling reduces manufacturing steps and logistics delay risks.
100% recycling of industrial scrap pieces within an eco-friendly manufacturing cycle.
Managing global distribution requires more than basic manufacturing. Shenghuang supports international procurers through optimized processes built to handle heavy logistics and strict compliance frameworks.
To reduce international shipping costs, our modular components are designed to stack optimally. A standard 40-foot High Cube (40HC) container can hold up to 350-400 pieces of our 1000x500x400 mm floating cubes, including standard connecting pins and accessories, drastically lowering maritime shipping freight fees per unit.
We work closely with client engineering departments to mold unique dimensions, specialty colors, or emboss corporate brand logos on the walking platforms. Our internal tooling center can deliver sample molds within 15-25 days depending on complexity, providing rapid feedback before final mass production.
We provide full verification profiles, including wall-thickness ultrasonic testing records, load-limit certificates, raw material safety sheets, and high-impact drop test reports, satisfying complex corporate purchasing and environmental audits.
Proudly manufacturing high-performance plastic molded products for global distributors, retailers, and commercial brands.










Entering international maritime markets requires adherence to local environmental codes and structural safety standards. Our platforms are designed to align with strict global policies.
Our docks undergo thorough load-bearing assessments to verify they exceed standard stability requirements. We calculate buoyancy distributions, shear force resistance on interlocking pins, and surface friction coefficients to confirm compliance with European safety regulations (EN15649) and ASTM watercraft safety criteria.
The pristine ecosystems of lakes and shorelines cannot tolerate chemical contaminants. All our plastic formulations are verified free of toxic heavy metals, lead compounds, and volatile phthalates, guaranteeing compliance with EU REACH and RoHS environmental standards.
We work hand-in-hand with regional marine contractors and engineering firms, supplying structural assembly videos, 3D CAD anchor design configurations, and local freight support to simplify project execution at any local port.

Floating Dock's modular design and superior quality hold up quite well in a typhoon depending on the installation. Our customers are reporting excellent results for the docks that were hit hand in all the typhoon.
Yes, In the areas where there is not a local dealer presence, we can ship your Floating Dock system directly to you local freight terminal for pickup.
Absolutely, The dock can be left in all year even in salt water. The Floating Dock system is designed to be left in the ice for the winter. The special design of the cube allows the dock to pop up on top of the ice.
The issue when it comes to ice and its affect on the system is water flow. If there is a heavy current or moving ice, the key question to ask yourself is, "When the ice thaws out, does it just dissipate back into the water level or are there large blocks of heavy flow ice moving around that would severely damage stationary docks?" If you answer "Yes" to the first part of the question, you can leave our dock in all year. If you answer "Yes" to the second part of the question, then your next move is as obvious as the ice will tear out and wash away any structure.
The cubes can be used as a floating platform, gangway, finger pier or any other type of customized configuration you so desire. Available walking platform must be at least three cubes wide. The dock is extremely stable to walk on and will support your body weights due to the balanced buoyancy of each cube (which is about 200 lbs).
Yes, you can use the dock anywhere you can drive your crafts. The cubes only draw about 2 to 4 inches of water with the craft off it. The minimum functional water depth is measured at the back of the dock where the drive-on takes place. The dock needs to be able to flex in order to drive on top of it. System is fine at rest on the bottom during low tides. The important thing is that there is enough depth at the stem of the dock to allow the boat to back off.
Our factory start our floating dock business from year 2019, is one of the earliest floating dock manufacturer in China. floating dock is becoming the largest floating dock supplier in China, offer the super quality floating dock products.
Yes. As a leading blow molding specialist, we can perform comprehensive OEM customized engineering. We design custom tooling molds to support client specifications, color matching, and private brand logo integration.
Our marine docks utilize virgin HMW-HDPE compounded with professional UV stabilizers rated UV-8 or higher, which prevents structural weathering for over 10 years of constant solar radiation.
