How Are Shipping Containers Made?

Shipping containers have revolutionized global trade, providing a secure, durable, and efficient way to transport goods worldwide. But how are these robust steel boxes manufactured? This article will take you through the process of making a shipping container, from raw materials to the final product.

Step 1: Raw Materials and Steel Preparation

The primary material used in making a shipping container is corten steel, also known as weathering steel. This type of steel is designed to withstand harsh weather conditions and resist rust. Large sheets of corten steel are cut and prepared to form the container’s walls, floor, and roof.

Step 2: Wall Panels and Flooring

The steel sheets are sandblasted to remove any impurities, then corrugated to add strength and durability. These corrugated panels are welded together to form the container’s walls. For the flooring, cross-members are welded to the bottom frame, and marine-grade plywood is installed, providing a strong base.

Step 3: Assembly and Welding

The individual panels are welded together to create the basic structure of the container. Reinforcements are added at the corners, as these points bear the most weight during stacking and transport. The doors, equipped with locking mechanisms and rubber seals for waterproofing, are then installed.

Step 4: Surface Treatment and Painting

Once the welding is complete, the entire container is sanded and primed to protect against corrosion. A layer of industrial-grade paint is applied, often in bright colors for easy identification. The paint not only adds to the container’s aesthetic but also serves as an additional protective layer.

Step 5: Testing and Quality Control

Every shipping container undergoes a series of tests to ensure it meets international standards. These tests include:

• Structural integrity tests to check the strength of the welds and panels.
• Waterproofing tests to ensure no leaks occur.
• Door functionality tests to verify smooth operation and security.

Step 6: Final Inspection and Delivery

After passing quality control, the container receives its identification markings and is prepared for shipping. It is then transported to distribution centers or directly to customers.

Summary

Shipping containers are built with precision and durability to withstand the rigors of global trade. Whether for transporting goods or repurposing into homes, offices, and storage units, these containers offer unparalleled versatility.
