Common Shipping Container Specs

Shipping container dimensions vary in length and width. Most commonly, containers are around 10-feet, 20-feet, or 40-feet long, each at around 8 feet wide. The height of each shipping container varies between standard height (8 feet 6 inches) and "high cube" (9 feet 6 inches), which are often used to increase storage space or create better air circulation. Check out the table below for a breakdown of shipping container dimensions and specifications.

How to Transport Modified Shipping Containers

You envision purchasing a mobile container office or equipment enclosure, but then it hits you: how will your container get from point A to point B? Following are some helpful insights from the Falcon Structures logistics team.


When to Put a Shipping Container on Wheels

Falcon Structures usually recommends customers transport their modified shipping container with a semi truck. However, occasionally there are cases where towing a container on a chassis – a frame on wheels that carries the container –is the best solution.

What You Can Expect from Falcon Structures’ Modified Shipping Containers

We know that you need your structures to be secure, durable and portable, which is why we build our wide range of standard portable storage, office and housing structures using standard ISO 20 ft or 40-foot Conex shipping containers. We also make custom structures with standard and 10-foot shipping containers.

Conex Shipping Container Materials and Construction


Portable ISO shipping containers require no foundations or structural assembly. Modified shipping containers are durable, weather-resistant and secure because they are built with:

  • 16-gauge vertically corrugated corten steel
  • Double, asymmetrical steel doors with ground-level entry
  • Heavy-duty, marine-grade wood flooring
  • Die-stamped steel roof

Used and One-Trip Containers

While 20-foot and 40-foot shipping containers are the norm, the age and condition of shipping containers vary greatly. At Falcon Structures, most of the containers we modify and sell fall into the “one trip” or “new” category. One Trip containers have made only one trip from China to the U.S. and are the best option for living and working spaces.

Falcon Structures also offers used shipping containers – those that have made several trips by land or sea – but we only recommend this option for limited applications. Since we always choose containers with modification in mind, we only offer certified, wind and watertight containers.

Modified Shipping Containers Create Reliable Structures

 Canon office interior solution

While the concept of creating durable standardized shipping containers originated in the United States, most shipping containers (also known as Conex or Connex containers, ISO containers, one trip containers, sea containers, ocean containers, ISBU containers, intermodal containers, etc.) are manufactured in China or Europe.

Shipping Container Testing and Standards

To get to the U.S., shipping containers travel by sea and must meet strict ISO manufacturing standards set forth by the International Maritime Organization (IMO). These standards ensure any cargo stored inside is protected from harsh elements experienced at sea, including wind, rain, snow, ice and heat. 

Once modified, containers provide a safe and sturdy environment suitable for storage, industrial enclosures, living quarters, office space, military solutions and more.
