Yellow Sentinel flat-deck sectional steel barge with red pin-flange connection pins in the yard

Pillar · Our Barges

Sectional steel barges.
Built in Canada.

Every model is built from CSA grade 350W steel, designed to CSA S16-14, and shares the same pin-flange connection system. Pick the Standard for general work, the Heavy Duty Crane for heavier payloads, and the Back Lake when it has to ship without permits.

Same hull. Different job.

CSA-grade steel. Every model uses CSA G40.20-13 / G40.21-13 grade 350W structural steel — Standard, Heavy Duty, Back Lake, and custom alike.

Welds and paint. ¼″ fillet welds unless noted, two-component epoxy exterior paint, engineered and stamped drawings.

One pin-flange system. The same double-head connector pin runs through every model, so any section pins to any other.

Questions

Barge Lineup FAQ

Pricing, specs, lead times, and delivery — straight answers.

Which barge should I start with?
Start with the Standard (36,000 lb evenly distributed). If the payload is heavier, move to the Heavy Duty Crane Barge (58 tons per barge with 1 ft freeboard per 41′4″ section). If it has to ship in Canada without permits, the Back Lake stacks two high on a truck.
Can I mix different models in one float?
All Sentinel barges share one pin-flange connection system, so sections pin together across the lineup. Depths differ between models, so tell us the mix and we will confirm the layout with your quote.
How many barges do I need for a crane platform?
It depends on the crane and the water. Send us the crane spec sheet and we will size the float and quote it.
