How Are Shipping Containers Made?
Containers have revolutionised maritime logistics ever since they were started to be used in the industry, as they enabled to increase the quantity of cargo shipped by sea at the same time and ensured the safety of goods. Containers would not have secured a stable position in the market if they were not reliable and safe, so sturdy construction makes them such.
Almost all the shipping containers are built from steel or aluminium, have a roof and hinged doors. The wall elements are attached to the rails and frame at the top and at the bottom.
The production of a container starts from the preparation of steel sheets that are cut in smaller steel sheets of required size. This is done in specialised factories. The steel sheets used for wall panels are sandblasted and primed in order to remove rust and dirt. Then they are corrugated for adding more strength and durability.
The final step to complete the wall panel is to weld square tubing onto the top and bottom of the wall. This tubing is used to weld the floor and roof to the wall later on.
After the production of the wall panels is complete, the manufacturers usually prepare a floor frame. The floor frame is made up of beams that are welded. Then the floor frame is sanded with a flap disc angle grinder to ensure there are no rough welding joints.
Like the side walls, the doors are mainly made out of corrugated steel for added strength and durability. Once the corrugated steel has been cut to size, it is encased in square steel tubing. The doors are then sanded smooth again to remove any rough welding joints.
The corner posts are then welded to beams and then the individual doors are welded in-place inside the beams.
Container Takes the Shape of a Box
Once the main production works of individual container elements are completed, the assembly of a container can be started. The door is fixed and welded, then the roof panel is lowered down onto the container, i.e., the final component required for the efficient functioning of a container.
Painting and Priming Works
The container is primed in order to ensure that additional layers of paint stick better to the container. Once the primer has dried, the container is spray painted several times. Multiple layers of paint are used to ensure the container is protected against the impacts of salt and water.
The wooden flooring is fitted on top of the floor frame. The plywood panels are varnished and screwed down to the steel floor beams.
Once the assembly of the container is completed, it is tested for watertightness, airtightness and defects. If the tests are successful, the container is completed and is suitable for storage and transportation of goods.
