1. Shipping Containers Are Made of Steel

The first thing to know about shipping containers is that they’re made from steel. Steel is a very strong, lightweight material that can be formed into any shape and used in various settings. The strength of the steel makes it great for shipping. This is because it can withstand the pounding and shaking that occurs during transport.

The overall strength of a steel box comes from its thickness and its shape. The longer and broader the box is, the more weight it can support without bending or breaking under pressure. However, there are also other factors at work here.

2. Shipping Containers Have a Lot of Rivets

Shipping containers also have a lot of rivets that hold them together and keep them sturdy. Each container has at least 40 or 50 rivets and many more screws and bolts. These all work to increase the strength of the container, hence the weight a container roof can hold.

The rivets help to keep the container together even if there are holes in the side or top of it from something hitting it during shipping. The rivets help keep all of the pieces together so that they do not fall apart and cause damage or injury to anyone nearby who could get hurt by falling metal pieces.

3. Shipping Containers Are Designed to Be Stacked

Shipping containers are built to withstand the pressure of being stacked on top of each other in a cargo ship. They also have to be able to stand up to rough motions as they travel around the world by sea.

The walls and floor of a shipping container must be strong enough to increase the weight a container roof can hold. But they also need to be light enough for easy transport by truck or rail car. This means they must be built out of lightweight materials. Light materials such as aluminum or steel that can still offer the strength needed for stacking them up on top of each other.

4. Shipping Containers Have Pillars

Shipping containers have pillars, or posts, that are located on the four corners of the container. These pillars form a part of the structure of the shipping container. The pillars are used to support the heavy weight of the cargo being carried in the container. Consequently, the pillars increase the weight a container roof can hold.

Important to note that the pillars are hollow inside. From simple physics, since stress/bending stress equals to force per given area (stress=F/A). Then we can say that since they are hollow, this reduces the cross sectional area, and in return increases the amount of stress the pillars can withstand.

This is to say that how much weight a shipping container roof can hold, is dependent on the strength of the pillars.
