About the length of the container
Here's all the inside dimensions and openings by container!
Containers were first used in the United States around 1920 to improve transportation efficiency. Initially employed in rail transport, they have now become the mainstay of sea transport.
We have entered an era in which containers are being mass-produced to international standards for marine transportation.
Nowadays, containers are not only used for transportation, but are also used as a tool for land storage (container warehousing), and can be conveniently used, for example, to store materials at a factory and transport them out of the factory when relocating or disposing of them.
IN THIS ISSUE, WE WILL FOCUS ON CONTAINER WAREHOUSES AND INTRODUCE THE INTERNAL CAPACITY (INTERNAL DIMENSIONS) AND CHARACTERISTICS OF THE OPENINGS FOR LOADING AND UNLOADING OF INTERNATIONAL STANDARD (ISO) AND RAILROAD CONTAINERS (JAPANESE STANDARD), WHICH HAVE A HIGH VOLUME OF DISTRIBUTION.
INTERNATIONAL STANDARD (ISO) CONTAINER
THERE ARE VARIOUS TYPES OF INTERNATIONAL STANDARD (ISO) CONTAINERS, SUCH AS DRY CONTAINERS, REEFER CONTAINERS (REFRIGERATED/REFRIGERATED), AND TANK CONTAINERS, ACCORDING TO THE CHARACTERISTICS OF THE CARGO. HERE IS AN INTRODUCTION TO DRY CONTAINERS, WHICH BOAST AN OVERWHELMINGLY LARGE AMOUNT OF DISTRIBUTION AND ARE USEFUL AS CONTAINER WAREHOUSES.
SIZE OF 40FT DRY CONTAINER
As an international standard (ISO), it is the most used container standard in the world.
40FT (feet) refers to the length of the container, and there are two patterns: a normal size with a height of 2591mm, and a size with a height of 2896mm, called a high cube (tall). The normal size (H:2591mm) is the most common.
The floor area is 28.3m2 (8.5 tsubo, 18 tatami mats), which is the size of a typical 1K~1DK. In an apartment or a single-family house, 18 tatami mats is the size corresponding to LDK, so I think you can imagine the size of the inside.
SIZE OF 20FT DRY CONTAINER
As an international standard (ISO), it is a standard for containers developed to transport smaller cargoes that are less than 40FT containers.
20FT (feet) refers to the length of the container, and there are two patterns: a normal size with a height of 2591mm, and a size with a height of 2896mm, called a high cube (tall). The normal size (H:2591mm) is the most common.
The floor area is 13.9 square meters (4.2 tsubo, 9 tatami mats), which is close to the size of a studio or a single room in a business hotel.
Features of the aperture
The opening is generally double-opening on one gable side, and the depth is quite wide, so it is common to use a forklift to bring in heavy items. In addition to the double opening on one gable side, there is also a double opening on one flat side (side opening), but the volume of distribution itself is not large.
If you need to store wide cargo (opening width exceeding 2350mm), side-opening containers are one of the options. However, there is a disadvantage that "large opening" = space is required to open the door. For example, in order to fully open the side opening of a 40FT container, a large space of 6m or more is required in front of the container. For land storage applications, the area required per container is larger, so it is necessary to select the right one for the purpose.
(Single gable side double opening)
It is mainly made of steel and only the internal floor surface is made of plywood.
Since the outer panels are made of steel, it is essential to paint them to prevent rust and they need to be maintained.

Japan's original standard railway container
THE RAILROAD CONTAINER WAS DEVELOPED WITH CONSIDERATION OF THE DOMESTIC RAILROAD CONDITIONS IN JAPAN, WHERE THE TRACKS ARE NARROW AND CURVES ARE FREQUENT. THEY ARE SMALLER THAN ISO (INTERNATIONAL STANDARDS) CONTAINERS, BUT THEY ARE STILL A HIGH QUALITY CONTAINER, AS THE JAPANESE PEOPLE PLACE GREAT IMPORTANCE ON TRANSPORTATION QUALITY.
12FT JR CONTAINER
The most common railroad container is a dry container with a length of 12 FT. Compared to
international standard (ISO) containers, the width and height differ only by about 10 cm, but the length is reduced from 20 FT (feet) to 12 FT (feet), resulting in a smaller content volume.
However, there is less demand for larger rail containers as they fit the domestic transport model of small lot, high frequency transport.
The most common type is the double flat side opening (side opening), in which both sides open.
Some of them have both gable side and flat side openings, and railway containers have a full range of openings.
In the case of 12FT containers, the installation area is not so large because the length of the door is not large enough for side opening.
If you are thinking of using it as a container warehouse, the side-opening type is recommended because of its easy loading and unloading.
(Flat side double-opening / Side opening)
The outer panel is made of steel, but plywood (veneer) is attached to the inner lining. This is a result of the ingenuity to prevent the cargo inside from being damaged, as high transportation quality is required for domestic transportation.
However, since the outer panels are made of steel, it is essential to paint them to prevent rust, and maintenance is required.

Summary of Container Lengths
Even if we say "container" in one word, there are various sizes depending on the standard.
In addition, the usage of the container changes depending on the difference of the opening and the inside construction.
We hope this article will help you to choose the best "container" for you.
