Conex Shipping Container Materials and Construction

This ISO standard portable storage container requires no foundations or structural assembly. It is wind and water-tight to protect your things from the elements. All of our storage containers are durable, weather-resistant, and secure because they are built with:

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

Shipping containers are a strong option for storage, offices, and workforce housing.


Built to Endure Harsh Weather Conditions

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.

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.

What You Can Expect with Falcon Shipping Containers

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

Falcon 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.
