How shipping container are constructed.

Containers are built from 4mm (⅜”) thick non-corrosive steel and square tubing frame. The sides are constructed from 14 gauge, 0.075” non-corrosive rolled steel that is corrugated to add rigidity and then welded to the steel frame.

The floor is made of the same square 4mm steel tubing for the frame and a plywood floor of 28mm (1 ⅛”) screwed to the cross braces.
The corner posts are designed to withstand 153,000 pounds allowing as many as nine containers to be stacked on top of one another, with a 7’2” x 7’6” door opening at one end.
A standard container is 20’ x 8’ x 8’6”. But 40-foot and 45-foot containers are just as common. An empty 20-foot container weighs approximately 5,500 pounds and can carry 65,000 pounds of goods.
Cargo statistics are calculated in TEU (20-foot equivalent units). The 40-foot container is considered to be 2 TEUs. With the arrival of new super freighters, the sizes of containers are increasing as well, some as long as 57ft.
The Eurozone is hesitant to adopt larger sized containers because of the older and narrow streets in many European cities. They make it hard for large trucks to navigate and causes congestions.
