Types of containers
growing container transport, load to meet the needs of different types of goods, so we had a different type of container. These containers are not only different in appearance, but also different in structure, strength, and size. According to the different purposes of the container, there are the following types.
1. Dry Cargo Container
is also called general cargo container, which is a general purpose container used to load general general cargo except liquid cargo, cargo requiring temperature adjustment and special cargo. This kind of container has a very wide range of use. There are two commonly used 20ft and 40ft. Its structure is often closed, and generally has a door on one end or side.
2. Top-Open Container
is also called open top container. This is a container without a rigid top, but a roof made of canvas, plastic cloth or plastic coated cloth supported by a foldable top beam. The cargo container is similar. The open top container is suitable for loading taller large cargo and heavy cargo that needs to be hoisted.
3. Platform Based Container
platform type container has no top and side walls, and even some end walls are removed and only the bottom plate and four corner posts are removed.
There are many types of gantry containers. Their main feature is: in order to maintain their longitudinal strength, the bottom of the box is thicker. The strength of the bottom of the box is greater than that of an ordinary container, and its internal height is lower than that of an ordinary container. There are ties on the lower side beams and corner posts, which can fasten the loaded goods. The platform type container has no water tightness, and the goods that are afraid of water can not be shipped. It is suitable for loading goods of different shapes.
Platform type containers can be divided into: open side platform type, full frame platform type, platform type with complete fixed end wall, and platform type container with only fixed corner posts and bottom plate without end.
A platform container is a container with only a bottom plate and no superstructure. The container is easy to load and unload, and is suitable for loading long and heavy pieces.
4. Ventilated Container
Ventilated containers are generally provided with vents on the side walls or end walls, which are suitable for loading goods that do not require freezing but need ventilation and prevent sweat, such as fruits and vegetables. If the vent is closed, it can be used as a grocery container.
5. Reefer Container
This is a container specially designed for transporting frozen or low-temperature cargo that requires a certain temperature to be maintained. It is divided into a built-in mechanical refrigerated container with a freezer and an external mechanical refrigerated container without a freezer.
Suitable for loading meat, fruits and other goods. The cost of refrigerated containers is relatively high, and the operating costs are relatively high. Pay attention to the technical status of the refrigeration device and the temperature required for the goods in the container during use.
6. Bulk Container
In addition to the door, the bulk container is also equipped with 2 to 3 loading ports on the top of the box, which is suitable for loading powder or granular goods. When using, pay attention to keeping the inside of the box clean and smooth on both sides to facilitate the unloading of the goods from the door.
7. Pen Container
This is a container specially used for loading livestock. In order to achieve good ventilation, the wall of the box is made of wire mesh, and there are cleaning ports and drainage ports under the side walls, and a feeding device is provided.
8. Tank Container
This is a container specially set up for the transportation of liquid cargo, such as alcohol, oil and liquid chemicals. It consists of a tank body and a box body frame. When loading, the goods enter through the top loading hole of the tank, and when unloading, they flow out through the discharge hole or suck out from the top loading hole.
9. Car Container
This is a container designed and manufactured specifically for loading small cars. Its structure is characterized by no side walls, only a frame and a bottom of the box, and can be loaded with one or two layers of cars.
Since containers are often affected by various forces and the environment during transportation, the materials used for the construction of containers must have sufficient rigidity and strength, and materials of light weight, high strength, durability, and low maintenance costs should be used as much as possible. It must be inexpensive and easy to obtain.
Materials for Containers
At present, the widely used containers in the world are classified according to their main materials:
1. Steel Container
its frame and the tank wall are made of steel. The biggest advantage is high strength, strong structure, good weldability and water tightness, low price, easy repair, and not easy to damage. The main disadvantages are self-weight and poor corrosion resistance.
2. Aluminum container
Aluminum container with a two: one for steel aluminum; only the other ends steel frame, with the remainder aluminum. The main advantages are light weight, non-rusting silicon watch, beautiful appearance, good elasticity, and not easy to deform. The main disadvantages are high cost and easy damage in collision.
3. Stainless steel containers
usually used stainless steel tank containers. The main advantages of stainless steel containers are high strength, no rust and good corrosion resistance, but the disadvantage is large investment.
4. Glass steel containers
FRP container is installed on a steel frame made of fiberglass composite panels. The main advantages are good heat insulation, corrosion resistance and chemical resistance, high strength (good performance, can withstand greater stress, easy to clean, easy to repair, large container volume, etc.; the main disadvantage is large dead weight, The cost is high.
General Sizes of Containers
At present, the dry containers commonly used in the world are:
1. The outer dimensions are 20 feet X 8 feet X 8 feet 6 inches, referred to as 20 feet containers;
2. 40 feet X 8 feet X 8 feet 6 inches, referred to as 40 Feet container;
3. 40 feet X 8 feet X 9 feet 6 inches, referred to as 40 feet tall container (used more in recent years).

internal volume 12.05 meters X2.12 meters X 1.96 meters, distribution gross weight 36 tons, volume 50 cubic meters.
The container sizes or types of various shipping companies will be different, but in general 20′ and 40′ containers are the same mostly.
