Structure and Flooring
Steel shipping containers have walls that are made from 14 gauge corrugated steel panels that are welded to the main structure. The top and bottom side rails and end frames are 7 gauge tubular steel. Containers are manufactured with a set of doors at the end. Some have doors at both ends and are called double door units (DD). All doors utilize the same mechanics to open, close and seal. the main weight bearing components of a container are the 4 corner posts. Each of these corner posts have “corner castings” at the top and bottom. these are for stacking and lifting purposes when transported on cargo ships. The height of the floor (inside) is roughly 6 3/4″ from the bottom of the corner casting. This 1-1/8″ marine plywood flooring is supported by steel cross members approximately 5 inches tall. The bottom of the cross member comes to just 5/8″ above the bottom of the corner casting. See photos for details. Click here for more information on the marine plywood used in shipping containers.
