In international trade, container shipping is a crucial transportation method for multimodal freight transportation. Container shipping has so many advantages like high standardization, great sealing, low damage rate, intensification, large-scale operation, regular shipping services, low cost, and good quality. It really enhances the safety and efficiency of freight transportation. Currently, international organizations responsible for setting freight container standards include the International Maritime Organization (IMO) and the International Organization for Standardization (ISO).

A container, also known as a cargo box or freight container, is a standardized box-type freight equipment that can be used repeatedly. It has a certain degree of strength, rigidity, and integrity, making it convenient for mechanical loading and unloading. Since containers can be easily transferred and transported, it has greatly expanded its spread and use around the world.

I. Basic Structure of a Container
A container is composed of an upper part and a lower part. The upper part is a frame structure consisting of an upper cover plate, four columns, and a lower pressing cover plate. The lower part is a frame structure consisting of four angle irons and a bottom plate. The main structure of a container is composed of a bottom plate, side walls, a ceiling, front, rear, left, and right doors, door hinges, door locks, and rubber sealing strips. Among them, the bottom plate is generally made of steel with a thickness of about 28mm. The side walls and ceiling are made of spliced steel plates with a common thickness of 1.5 to 2.0mm.
II. Reinforcement of Containers
To improve the transportation safety of containers and increase their carrying capacity, containers are usually reinforced at the corners and connection plates. Corner reinforcement mainly involves welding a steel triangle at each of the four corners of the container through angle irons, increasing the tightness of the connection between the corners and the container bottom plate. Connection plate reinforcement is achieved by welding and strengthening the connection plate at the bottom of the container corresponding to the bottom plate, further enhancing the connection firmness and carrying capacity of the container.III. Sealing of Containers
To ensure the safe transportation of goods in containers, containers must have good sealing performance. The sealing of containers is mainly guaranteed by the sealing strips of the front, rear, left, and right doors. Generally, rubber strips are used as sealing strips, which have good sealing performance and durability. In addition, before installing a container, check whether the sealing strip is intact to avoid leakage and other problems during transportation.
IV. Rust Prevention of Containers
Containers are generally made of steel materials and are prone to rust during long-term use. To improve their service life and aesthetics, rust prevention treatment can be carried out after the container is manufactured. Coating is the main rust prevention method. Currently, commonly used rust prevention coatings for containers on the market include epoxy coatings, polyurethane coatings, and others.
Conclusion: By understanding the basic structure, reinforcement, sealing, and rust prevention of containers, we can better ensure the safe transportation of goods and improve transportation efficiency. When choosing a container, we can also select the appropriate container type and size according to our own needs to meet different transportation requirements.
