Types and introduction of Marine Containers
1、 Classification by materials used
According to the materials used in the main parts (side wall, end wall, top, etc.), containers are called containers made of what materials. According to the classification of materials used, containers can be divided into three types:
1. Aluminum alloy container has the advantages of light weight, beautiful appearance, anti-corrosion, good elasticity, convenient processing, low processing cost and repair cost, and long service life;
2. Steel container has the advantages of high strength, strong structure, high weldability, good water tightness and low price; its disadvantages are heavy weight and poor corrosion resistance;
3. FRP container has the advantages of high strength, good rigidity, large volume of contents, good heat insulation, anti-corrosion, chemical resistance, easy cleaning, and easy repair; the disadvantages are heavy weight, easy aging, and low strength at the screw bolt.
2、 Classification by structure
According to the structure, containers can be divided into three categories:
1. The inner post type container and the outer post type container mainly refer to the aluminum alloy container. The inner column container refers to the side column (or end pillar) located in the inverted wall or end wall; the outer column container refers to the side column (or end pillar) located outside the inverted wall or end wall;
2. Folding container refers to that the main components (side wall, end wall and top) of container can be simply folded or disassembled, and can be easily reassembled when used again;
3. The monocoque container is a steel body composed of all parts. It has the advantages of light weight and can adapt to the torsion without permanent deformation.
3、 Classification by purpose
1. General container
Ordinary container, also known as dry container, is mainly used to transport articles and groceries. It is usually used to transport cultural goods, daily necessities, medicine, textiles, handicrafts, chemical products, hardware and electrical equipment, electronic machinery, instruments and machine parts. This kind of container accounts for 70 ~ 80% of the total number of containers. In addition to frozen goods, live animals and plants, dry containers can be used for goods suitable for container transportation in terms of size and weight.
2. Frozen container
There are two types of reefer containers: external and built-in. The temperature can be adjusted from - 60 ℃ to + 30 ℃. In the process of transportation, the built-in container can start the refrigerator at will to keep the specified temperature, while the external type must rely on the refrigerator equipped on the container special vehicle, ship, special yard and station. This box is suitable for transporting butter, chocolate, frozen fish, condensed milk, margarine and other items in summer.
3. Open top container
Open top container, It is also called open top container. This kind of container does not have a top, but has a roof made of canvas, plastic cloth or plastic coated cloth supported by folding top beam. The cargo can be loaded and unloaded from the top of the container by crane. The container with open top or without fixed surface is covered with waterproof cloth during shipment, and its watertightness requirement is the same as that of dry cargo box. It is suitable for loading heavy goods such as glass plate, steel products and machinery.
4. Frame container
The flat rack container has no top and sides. It is characterized by loading and unloading from the side of the container. The main object of transportation is overweight goods, which is easy to load livestock, and naked goods such as steel which can be exempted from outer packaging. It can also facilitate the hoisting of large, ultra wide and ultra-high goods.
5. Container livestock
A pen container with metal mesh on the side, good ventilation and easy feeding. It is a special container specially made for transporting cattle and horses.
6. Tank container
Tank container is also called liquid container. It is a special container for the transportation of food, medicine, chemicals and other liquid goods. The structure is to fix a liquid tank in a metal frame. International standard tank is a kind of stainless steel pressure vessel installed in a fastening external frame. The tank inner tank is mostly made of 316 stainless steel. Most tanks have steam or electric heating devices, inert gas protection devices, pressure relief devices and other optional equipment for fluid transportation and handling.
7. Platform container
The shape of platform container is similar to railway flat car. It is a container with high bearing capacity and no superstructure. It is suitable for loading overweight and ultra long goods, with length of more than 6 meters, width of more than 4 meters, height of 4.5 meters and weight of 40 tons. Moreover, the two platform containers can be connected to hold 80 tons of goods. It is very convenient to use this kind of box to transport vehicles.
8. Ventilated container
There are 4-6 ventilation holes on the wall of the vented container, and the inner wall is coated with plastic layer. It is suitable for loading hot and stuffy goods such as fresh vegetables and fruits.
9. Insulated container
The insulated container has heat insulation layer in the box, and the air inlet and outlet can adjust the angle on the top of the container. The outside air and wind direction can be used to adjust the temperature in the container. When it is closed tightly, it will not be affected by the external temperature for a certain period of time. Suitable for shipment of goods sensitive to temperature and humidity.
10. Bulk container
Generally, there are 2 ~ 3 small hatches on the top of the bulk container for loading. There is a lifting frame at the bottom, which can be raised to an angle of 40 ° for unloading. This kind of box is suitable for bulk cargo such as grain and cement. If you want to carry out plant quarantine, you can also fumigate and steam wash in the box.

11. Bulk powder container
The Freeflying bulk material container is basically the same as the bulk container, but the nozzle and suction pipe are used for loading and unloading.
12. Hanging container
The paper discusses the application of the paper container to the container of clothing goods. With the development of international trade, the commodity structure changes constantly, and various types of special or multi-purpose containers will appear in the future.
The above is about the types and introduction of shipping containers. Welcome to the logistics customer service, we will serve you with a professional attitude.
