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.

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.
- If you're doing general marine contractor work — bridge, piling, dredging — start with the Standard Barge. If your job involves heavy cranes or choppy water, choose the Heavy Duty Crane Barge for its 7′ depth. For remote lakes accessed by truck, the Back Lake Barge stacks two-high without permits.
- Yes. All Sentinel barges use the same pin-flange connection, so you can combine Standard and Heavy Duty sections in the same configuration. Back Lake barges have a different width and pin to one another.
- It depends on the crane weight and the water conditions. As a rule of thumb, a 60-ton crawler crane typically needs four Heavy Duty sections. We size every job — call us with your crane spec sheet and we'll confirm.
