Sectional barge
vs pontoon barge.
Compare the manufacturer’s current specifications with Sentinel’s published sectional barge sizes, payloads, connections and transport options.
Compare the manufacturer's current specifications when choosing a pontoon or sectional barge for your project.
What is a pontoon barge, really?
A pontoon provides buoyancy; sectional describes a platform assembled from modules. The product specifications determine suitable loads and use.
Confirm deck loads, dimensions, transport and engineering documentation for the configuration you intend to use.
What makes a sectional barge different
Sentinel sells the Standard 10×40 sectional steel barge: 10 ft × 40 ft, 36,000 lb evenly distributed deckload and pin-flange connections. Confirm the intended equipment, loads, accessories and layout with your quote.
The Standard 10×40 barge has a 36,000 lb evenly distributed deckload. Have the equipment loads and platform layout reviewed before use.
Precisely aligned holes give a solid connection after just two double-head connector pins. Many simple connections spaced close together distribute stress across the whole joint, so no single pin becomes a critical stress point. Pin every hole before starting a project. Pins resist corrosion jamming, and the double heads make connection and removal quick. Easy assembly and disassembly make transport quick.
Standard 10×40 barges ship across the United States and Canada. Routing, permits, site access and delivery dates are confirmed with your quote.
