Stable steel pontoons designed to support excavators, cranes, and heavy site equipment in demanding marine environments.
Other common applications:
– inland cargo transport
– timber and material handling
– temporary river crossings
– floating access platforms
– custom industrial applications
No deck barges match your load capacity requirements.
For projects that require transport in sections, flexible configurations, or frequent reassembly, we also offer Modular Pontoon Sections.
Explore Modular Pontoon SectionsThese terms are often used interchangeably in the marine construction industry. In practice, they all refer to flat-deck steel floating platforms used to support equipment, materials, or site operations on water. Depending on region, application, or company background, they may be called steel pontoons, work pontoons, flat-top pontoons, construction barges, or excavator pontoons. At Stalmar, we design and build custom steel pontoons and barges configured specifically for the intended load, equipment, and operating conditions — regardless of terminology.
Yes. Our steel pontoons are engineered to carry heavy equipment such as excavators, drilling rigs, or lifting machinery. We match deck strength, buoyancy, width, and load balance to the exact equipment you plan to use. This ensures stable and predictable operation on the water.
Yes. Steel pontoons are commonly assembled into floating work platforms, access pontoons, or temporary construction platforms. We can supply pontoons as single units or as combined multi-section platforms depending on your project.
Yes. We can deliver pontoons prepared for spud installation or equipped with complete spud and winch systems, depending on your needs. Tell us how the platform will be used, and we’ll recommend the correct layout and reinforcement.
Lead times depend on the selected pontoon size and our current production schedule. Some components may be available immediately, while larger builds require planned production slots. We provide an indicative build and delivery timeline when you request a quote.
We arrange delivery by road or sea, depending on size and destination. Transportation is coordinated directly with you to ensure the most practical and cost-efficient solution. All pontoons are delivered with the necessary documentation and preparation for on-site assembly.
Yes. We provide continued support for maintenance, repairs, and spare components. Our technical team remains available to help with operational questions and ensure minimal downtime.
To recommend the right pontoon configuration, we typically need:
• required load capacity
• target deck size or working area
• equipment type and weight (if machinery will be installed)
• brief description of how the platform will be used
• project location and delivery region
Based on this, we assess buoyancy, stability, deck strength, and overall feasibility — and then propose a suitable solution.
