Sentinel modular barges

Pillar · Our Barges

Sectional steel barges.
Built in Canada.

Every Sentinel barge uses the same pin-flange system, the same CSA-grade steel, and the same robotic welds. Choose the model that fits your project — and combine sections to build any size you need.

All barges share the same DNA.

CSA-grade steel. Every barge is fabricated from CSA G40.20-13 / G40.21-13 grade 350W structural steel.

Robotic welds. Bohler Ti 52 T-FD flux core wire delivers continuous, uniform welds — every joint, every barge.

Pin compatible. Mix and match sections across our entire lineup. The same pinning system runs through every model.

Barge Lineup FAQ

Direct answers about heavy deck barges, charter terms, and global delivery.

Which barge should I buy?+
For general marine contractor work — bridge, piling, dredging — start with the Standard. For heavy cranes or choppy water, the Heavy Duty Crane Barge with its 7′ depth. For remote lakes accessed by truck, Back Lake stacks two-high without permits.
Can I mix different models in one float?+
Yes. Same pin-flange across the lineup, so you can combine Standard and Heavy Duty in the same configuration. Back Lake is a different width and pins to other Back Lakes only.
How many barges do I need for a crane platform?+
Depends on crane weight and water. Rough rule: a 60-ton crawler typically wants four Heavy Duty sections. Send us the crane spec sheet and we'll size it.
