Marine steel pontoon
Product Overview
Marine Steel Pontoon is a heavy‑duty modular floating structure
manufactured from high‑strength marine‑grade steel plate, with full
welded construction, closed‑cell foam filling, and professional
anti‑corrosion treatment. It delivers stable buoyancy, high load
capacity, impact resistance, and long service life in saltwater,
freshwater, and offshore environments. Widely used for floating
docks, ferry terminals, work platforms, temporary floating bridges,
marine engineering support, and waterfront infrastructure.
Core Features
Premium Structural Steel: Adopts marine‑grade steel (Q235B / CCSB equivalent) with reliable
weld integrity and structural rigidity.
Closed‑Cell Foam Filling: Fully filled with closed‑cell polyethylene foam; unsinkable even
if the outer shell is damaged.
High‑Level Anti‑Corrosion: Sandblasting + hot‑dip galvanizing + two‑component marine epoxy
coating for long‑term saltwater resistance.
Modular & Connectable: Standard or customized modules for fast assembly, disassembly,
transport, and on‑site expansion.
Strong Buoyancy & Loading: Uniform load capacity 200–700 kg/m²; buoyancy ≥500 kg/m³; stable
under wind and wave conditions.
Safe & Durable: Non‑slip deck, reinforced lifting/mooring eyes, zinc sacrificial
anodes, long service interval.
Applications
- Floating docks & marinas
- Ferry terminals & passenger floating piers
- Offshore construction work platforms
- Temporary floating bridges & access ways
- Marine engineering support & salvage barges
- Water leisure platforms & waterfront facilities
Advantages
- Heavy‑Duty & Long Life: Steel structure with multi‑layer anti‑corrosion ensures years of
maintenance‑light use.
- Unsinkable Safety: Foam‑filled design eliminates sinking risk; improves project
safety.
- Flexible Configuration: Modular design adapts to different water areas and load
requirements.
- Easy Installation: Quick connection and mooring; short construction period.
- Wide Adaptability: Stable performance in harsh marine environments.
