Do you know that ships carry approximately 90% of the world’s cargo? It’s no wonder that several different types of shipping containers are in use to handle such a huge number of items, each having a different purpose. Before selecting air freight services, you must understand the type of container you will be needing.
The 11 most popular types of shipping containers are described in detail below. As well as options for weighing or lifting them onto and off the frame.
General Purpose Container
A “dry jar” is another term for a general-purpose container. With a sturdy roof, sidewalls, and bottom, these shipping containers are fully sealed, weatherproof, and safe from the elements. The most popular type of container is the dry container, which is used to load most regular air freight cargo types. Besides, general-purpose containers may be customised with additions like liner bags or for shipping liquids.
Flat Rack Containers
The sides of this basic storage container can be folded to create a flat shelf. Since the end walls are stable enough to secure the freight, they are suitable for transporting oversized items like heavy equipment, trucks on rails, large reels, and building materials. Some 40′ flat rack shipping containers will transport up to 45 metric tons of freight!
Open Top Containers
A convertible roof on an open-top shipping container can be removed. This is appropriate for freight that is over-height and cannot be conveniently loaded through the ramp, such as tall equipment or other heavy/bulky finished goods that require the use of a crane or moving bridge for managing and stacking. Lashing rings are mounted on the upper and lower sides of open-top containers.
Double Door Containers
This type of container is also regarded as a “tunnel container” because it has doors on both sides. Double-door containers are ideal for easy loading and unloading materials, and they provide even more space for items like steel and iron. Both sets of doors have the same locking mechanisms and weather-tight seals to shield cargo from the environment.
High Cube Containers
The arrangement of high cube shipping containers is identical to that of general containers, but they are around one foot higher. These containers are available in 40′ and 45′ lengths and are used where a slightly greater volume capacity is needed. The front end of most high cube containers has a gap in the floor to base the container on the so-called gooseneck chassis, allowing it to sit lower and broader.
Open Side Containers
The only difference between open side containers and standard, general-purpose shipping containers is that the doors will often open entirely on the side. This function allows for much more space and entry, making loading and unloading goods much easier. Open side shipping containers are available in 20′ and 40′ lengths, and they provide ample space for extra-large products that can’t fit through standard doors.
ISO Reefer Containers
Temperature-sensitive and perishable cargo such as foods, fruits, and vegetables are delivered in ISO shipping containers. The temperature is regulated by external power in this container form. Reefers are usually made of weathering steel called ‘Cor-ten’ steel and are available in 20′ and 40′ lengths.
Like an ISO Reefer container, an enclosed or thermal container has a temperature control mechanism that allows it to survive higher temperatures. To cool or heat the air inside the bottle, they provide electrical compliance (mechanical compressor). A vacuum flask, equivalent to a “thermos” bottle, is used to make insulated glasses. As a result, they’re ideal for transporting goods like food, pharmaceuticals, tissues, blood, biological materials, and chemicals over long distances.
These are some of the most common types of shipping containers used in sea cargo.
