Explore our premium-tier blow-molded industrial products and high-buoyancy modular docking platforms engineered to global marine standards.
Pioneering High-Performance Polymer Marine Infrastructure & Custom Blow Molding Solutions Since 2019
Established in 2019 in Huangyan, Taizhou, Zhejiang Province—the renowned heartland of industrial mold fabrication and plastic manufacturing in China. Shenghuang has evolved into an ISO 9001 certified engineering leader in large-scale structural blow molding, producing high-buoyancy modular pontoons, marine systems, and custom industrial packaging.
Our facility runs continuous, state-of-the-art automated blow molding lines. This equipment enables high-precision thickness profiling and uniform material distribution across complex configurations, ensuring every pontoon meets exact structural load tolerances under extreme hydrostatic pressure.
Committed to eco-friendly marine stewardship, Shenghuang processes 100% recyclable, non-toxic High-Density Polyethylene (HDPE). Our marine products release zero microplastics or chemicals, complying with global regulations for installation in ecologically sensitive marine conservation zones.
The global marine leisure and commercial harbor industry has witnessed a paradigm shift from traditional timber and concrete docking systems toward modular, high-molecular polymers. As personal watercraft (PWC) continue to scale up in dry weight—largely driven by heavy-duty 3-seater designs and high-performance supercharged models—single-berth layouts are increasingly insufficient. High-density marinas, commercial rental agencies, and luxury residential waterfronts require efficient space optimization. This demand has accelerated the adoption of the Double Jet Ski Floating Dock.
OEM customization lies at the center of this transition. Waterfront operators require specific load capacities, tailored configuration pathways, and aesthetic consistency with existing installations. Our factory acts as a direct engineering partner. We deliver robust Double Jet Ski Dock systems capable of bearing dual PWCs up to 2,000 kg total payload without experiencing structural sag, lists, or mooring failure.
Our marine pontoons utilize High-Density Polyethylene (HDPE) reinforced with proprietary anti-UV, anti-oxidant, and anti-static compounds. The material chemistry is optimized to combat structural degradation caused by continuous exposure to salt water, solar radiation (UV15+ protection), and mechanical abrasion from incoming watercraft hulls.

A double jet ski floating dock must address key physical challenges: center-of-gravity shifts during drive-on maneuvers, side-by-side hull clearance, and mooring load concentrations. Our design features an engineered entry channel with a graduated slope (V-shape incline). The split layout balances the load across a wider surface area. Under normal operations, this prevents watercraft listing or drift-off.
The roll-on/roll-off process uses low-friction slide guides and optional integrated rollers. By reducing direct friction between the dock surface and the PWC hull, we extend the lifespan of the dock's HDPE wear plates and prevent damage to gel coats. Additionally, the twin-hull configuration allows operators to moor two watercraft with a shared utility lane down the center. This design optimizes usable deck space and minimizes the mooring hardware needed at the harbor line.
Our design, development, and production processes are audited and certified to conform to international quality and environmental standards.
