What are container floors made of?
Container
flooring is made up of two basic parts—steel cross-member supporting the
floor and a wood floor. The combo makes for a super strong and very watertight
floor to your container. Steel cross-members span the width of the container.
They are spaced out about every 4-6″.
Today we’re going to explore that in more
detail.
Container flooring is made up of two
basic parts—steel cross-member supporting the floor and a wood floor. The combo
makes for a super strong and very watertight floor to your container.
Steel cross-members span the width of the
container. They are spaced out about every 4-6″. They are about 5″
high. This framework to the flooring gives it strength. A 20′ container weighs
5,000 pounds, but it can hold 62,000 pounds. That is more than you are allowed
to drive down a highway without a special permit.
Marine-grade plywood is screwed into the cross-members. Marine-grade plywood is plywood that has been treated to make it more waterproof and insect-proof. Also, an additional coat is put on the bottom of the wood to create even more of a moisture barrier. The plywood is ¾” thick.

The result is that you have a nice, strong floor that will stay dry even if there is moisture under the container. However, if your flooring should wear out, it is also easy to replace. Unscrew the section that needs replacing (or even part of a section that needs replacing) and screw in a replacement piece.
