In the 1950s, trucking magnate Malcom McLean changed the world when he got frustrated enough with the speed of trucking and traffic to start a commercial shipping company in order to move goods up and down the eastern seaboard a little faster. Within ten years, containers were standardized, and the first international container ship set sail in 1966. The cargo? Whisky for the U.S. and guns for Europe. What was once a slow and unreliable method of moving all kinds of whatever in barrels, bags, and boxes became a streamlined operation — one that now moves millions of identical containers full of unfathomable miscellany each year.

When I started writing this, there was a container ship stuck in the Suez canal that had been blocking it for days. Just like that, a vital passage became completely clogged, halting the shipping schedule of everything from oil and weapons to ESP8266 boards and high-waist jeans. The incident really highlights the fragility of the whole intermodal system and makes us wonder if anything will change.
We are all used to seeing the standard shipping container that’s either a 10′, 20′, or 40′ long box made of steel or aluminum with doors on one end. These are by far the most common type, and are probably what come to mind whenever shipping containers are mentioned.
These are called dry storage containers, and per ISO container standards, they are all 8′ wide and 8′ 6″ tall. There are also ‘high cube’ containers that are a foot taller, but otherwise share the same dimensions. Many of these containers end up as some type of housing, either as stylish studios, post-disaster survivalist shelters, or construction site offices. As the pandemic wears on, they have become so much in demand that prices have surged in the last few months.
Although Malcom McLean did not invent container shipping, the strict containerization standards that followed in his wake prevent issues during stacking, shipping, and storing, and allow any container to be handled safely at any port in the world, or load onto any rail car with ease. Every bit of the container is standardized, from the dimensions to the way the container’s information is displayed on the end. At most, the difference between any two otherwise identical containers is the number, the paint job, and maybe a few millimeters in one dimension.
Standard as they may be, these containers don’t work for every type of cargo. There are quite a few more types of shipping containers out there that serve different needs. Let’s take a look at some of them, shall we?
Flat rack containers are basically platforms with no walls or roofs that are used to transport things like pipes, machinery, timber, buses, and boats. In other words, anything large or bulky that needs to be loaded and unloaded from the top.
Some flat rack containers have collapsible sides that make the cargo easy to remove, and others’ sides are fixed in place. Collapsible flat racks can be stacked together — a stack of four is about the size of a dry storage container. Flat racks come in both 20ft and 40ft sizes, though the widths and heights are often similar between the two.
