Have you ever wanted to know how a shipping container is made to be so durable? Shipping containers are made to be able to withstand even the toughest conditions. They are all made to an international standard so they they can be transferred, stacked, and shipped with ease.
Modern shipping containers are made from corten steel, also known as ‘weathering steel’.
All the containers that we receive in our ports are made in a factory in China. The primary material is a huge roll of corten steel.
The main components of shipping containers are cut from these rolls of steel. The cut sections of steel are sand blasted and primed. This process removes all dust and any contaminates from the steel surface.
The next step in the process is to corrugate the steel. This is important because is greatly increases the strength of the steel.
This is how a shipping container is made to be strong enough so that several units can be stacked on top of each other.
After they have been corrugated, the wall panels are welded together and square tubing is welded to the tops of the container walls. The door, then walls and corner posts, are installed on the floor frame. Everything is welded in place. The roof panel is the last to be assembled and welded to the container. The container is then primed and painted to add another layer of protection.
The floor panels are made from wood that has been treated with insecticide. These are varnished, and installed in the floor frame.
Lastly, rubber seals are fitted around the door, and the bottom of the container is waterproofed.
