    • With a rotomolded aluminum-and-plastic composite body, ensure long-lasting durability in saltwater and harsh marine environments.

  • 2. Enhanced Drainage & Structural Rigidity

    • With dual ventilated lids and ribbed textured walls, achieve optimal drainage and reinforced structural integrity for stable buoyancy in rough waters.

  • 3. High-Performance Buoyancy & Load Capacity

    • With seamless rotational molding and die-casting processes, deliver a watertight structure capable of supporting heavy loads up to 500kg.

  • 4. Versatile Marine Scenario Solutions

    • Designed for commercial marine applications, the pontoon provides reliable floating support for docks, buoys, and river/sea markers, outperforming lightweight home-use floats.

  • 5. Marine-Grade Material Compliance

    • Constructed with aluminum and plastic materials adhering to marine safety standards, ensuring environmental and operational reliability.

Product details

Plastic Rotomolded Floating Dock Pontoon Made by Aluminum Rotation Mold Buoy River Drogue Sea Dobber

The Plastic Rotomolded Floating Dock Pontoon combines lightweight durability and versatile design for aquatic and storage applications. Crafted via rotational molding and die casting, this aluminum-plastic hybrid pontoon features a ribbed structural design, dual-ventilated lids, and customizable dimensions. Ideal for docks, drainage systems, or buoy applications, it balances strength with ease of transport through ergonomic handles and precise measurement markings.

Supplier's note

  1. Technical Breakthroughs:

    • Rotational molding: Ensures seamless joints, reducing leakage risks by 30% vs. welded pontoons.
    • Dual-ventilated lids: Improve airflow by 40%, extending storage shelf life for agricultural produce.
    • Aluminum-plastic hybrid: Combines marine-grade corrosion resistance with 25% lighter weight than all-aluminum models.

  2. Version Selection Guidance:

    • Base Model: Ideal for small-scale docks or temporary storage (e.g., weekend lake houses).
    • Advanced Model: Targets commercial marinas or farms needing moderate buoyancy and customizable drainage.
    • Pro Model: Engineers heavy-duty applications like offshore buoys or industrial waste containment, where extreme durability and bespoke designs are critical.
      Example: The Pro’s 700 kg/m³ buoyancy allows safe deployment in stormy seas, while its UV-resistant shell maintains integrity under prolonged sun exposure.
