Marine plywood flooring

Also called Container plywood floor, Apitong flooring

Definition

Marine plywood flooring is the dense, multi-ply hardwood decking that shipping containers traditionally ship with from the factory, screwed down to the steel floor cross-members and built to carry loaded pallets and forklift traffic without flexing. It's the standard container floor material, though some newer containers use bamboo flooring instead.

What varies from one used container to the next

The floor is one of the parts of a used container that genuinely varies unit to unit. Two boxes of the same size and grade can have floors in different shape depending on what they hauled, how many years they spent working, whether a section was ever patched, and how they were stored before they got to us. One factory spec doesn't describe every floor sitting in a yard.

That's different from the wall steel, where the gauge and grade are consistent across the board. Flooring wear is the individual history of that specific container, not a fixed spec you can quote sight unseen.

How to pin down what's under your feet

The honest way to know the condition of a specific container's floor is to walk into it and look, press a boot down on any section that looks stained or soft, and check the corners where moisture tends to collect first. We're not going to hand you a blanket floor rating that applies to every used box on the lot, because it wouldn't be true of all of them.

If you're buying sight unseen from a broker instead of a local yard, this is exactly the kind of thing you can't check that way. Walking the actual container is the only way to know.

What marine plywood flooring is built to take

When it's sound, this flooring is built to handle exactly what a container sees in service, pallets loaded and unloaded repeatedly, forklift traffic driving straight over it, and years of weight sitting in one place without sagging. It's a working floor, not a finished one, which is why people who convert a container into a workshop or office often add a subfloor over it.

Wear signs worth checking before you buy

Look for soft spots underfoot, dark staining that suggests standing moisture, and any patched or replaced sections that don't match the surrounding boards. None of these automatically rule a container out, used equipment shows use, but they're worth seeing with your own eyes before you commit, not learning about after delivery.

It's the traditional standard, but not universal. Some newer containers ship with bamboo flooring instead. Check the specific unit if the floor material matters to your plan.
Floor sections can be repaired or swapped as part of our modification work. What that involves depends on the container and the damage, so it's a conversation for a specific box, not a blanket answer.

Check a floor with your own boots before you decide

We'd rather have you look at the actual container than take our word for a used floor's condition.
