What types of metals are used to build shipping containers

Shipping containers are durable boxes made of various materials so that they can hold up in the vast oceans they sail on. They transport a variety of items we use to make our lives more convenient like computers, TVs, bedding, clothing, etc. Shipping containers are up against snowstorms, pounding rain, high-speed winds, and the glare of the sun for hours on end. Their unique manufacturing process and the materials used to create them are what make shipping containers impervious to the harsh conditions they face.

Materials

Shipping containers are typically made from corten steel which is a self-healing/weathering steel. The strength of this material has revolutionized the way we transport cargo across large bodies of water. It has helped ensure the safety of the load and increased the overall carrying capacity. The most common sizes of shipping containers are 20, 30, and 40 feet and also come in refrigerated designs. For the most part, they all have closed tops, hinged doors, and corrugated walls that are welded to the end frames and rails.

Production

  1. Each container starts with a roll of steel that is cut into several sheets.
  2. They are then sandblasted and primed to remove debris and contaminants.
  3. The sheets get corrugated to improve their overall strength.
  4. Floor braces and roof panels are made, and wall panel sheets are welded together.
  5. Square tubing is fused together on the top of the walls.
  6. Floor panels can then be assembled to create the floor frame.
  7. Corner post and door assembly are also completed separately.
  8. Once the door is completed, it is installed on the floor frame, and then the wall panels are installed after.
  9. The door assembly, wall panels, and corner posts are welded together.
  10. Then, the roof panel is assembled and welded.
  11. Priming and painting can be done at this point.
  12. Wood frames with varnish are used to prepare for flooring.
  13. Holes are drilled in the floor panels once they are fixed to the container floor.
  14. Rubber seals and door hardware is installed for a watertight seal.
  15. The bottom of the container is also made waterproof and water tightness testing is conducted.
  16. Finally, the box is completed and inspected for any errors.

Protection

There are several ways to keep your shipping containers in good condition regardless of what you plan to use it for. While a primer is applied to shipping container steel to slow down rusting, it does not prevent it from rusting altogether. That is why you should pay extra attention to any horizontal area, dent, or pocket on your shipping container. If water sits on the surface for too long, it can speed up the oxidation process, leading to more rust forming. You should also pay attention to welding seams and apply an extra coat of rust-resistant paint on them. It will cover small chips and cracks that you might not see, increasing the stability of your container.
