sea can

What varies is the region, not the box

Where you hear the term sea can depends more on geography than on the container itself. It's the standard word for a shipping container across Canada, and it drifts south into the northern border states, Pennsylvania, Michigan, upstate New York. Head further south into Virginia and the Carolinas and conex or just container gets said far more often, though sea can still turns up in listings and searches from buyers who picked up the word elsewhere.

None of that regional drift changes the product. A sea can in Ontario and a container in Woodlawn are built to the identical ISO standard: same corner castings, same corrugated Cor-Ten steel, same 20-ft and 40-ft lengths.

What the word never tells you

A sea can carries no information about size, grade, or condition. It could mean a rusted-through unit somebody's trying to unload, or a nearly new one-trip box, or anything in between. Two different sellers can call the exact same container a sea can and mean two very different things about how sound it is.

The way to pin it down is to skip the naming word entirely and ask the questions that actually describe the box: what size, what grade, and what the walk-around shows. Our guide to 20-ft vs 40-ft sizing covers the first question, and our container types page covers grade.

If you called us about a sea can

Call it a sea can, a conex, or just a container, and you'll get the same answer here: we sell and rent 20-ft and 40-ft steel boxes, used cargo-worthy or one-trip, delivered free within 75 road miles of Woodlawn. The word you used to describe it on the phone changes nothing about what we quote.

It's worth saying plainly: unlike some of the military and overseas terms floating around this glossary, sea can isn't describing a product we don't carry. It's just another name for the exact box sitting in our yard. That puts it closer to conex than to something like a quadcon or a pallet-wide container, terms for units built to a different standard entirely.
