The composition of the container

CONTAINER, WHICH REFERS TO A LARGE LOADING CONTAINER WITH A CERTAIN STRENGTH, STIFFNESS AND SPECIFICATIONS FOR TURNOVER. There are many types of containers, and their uses are very different. Today we're going to talk about small details that you may not be very clear.

A container, also known as a container or container, is a kind of container freight equipment that is produced according to specifications and standardization, which can be used repeatedly, and has a certain strength, rigidity and integrity to facilitate mechanical loading and unloading. Since the container can be easily transferred and transported, it has greatly expanded its spread and use around the world.

The structure of the container is mainly divided into the following parts: steel frame, wavy side wall panels that form the box enclosure, floor and its additional beams, opening door leaf and its auxiliary parts, and various loading and unloading components. The various components are welded to each other to form a complete and independent box structure.

Container number (the container number of which the goods are shipped for export)

A standard container number consists of an 11-digit code and consists of three parts.

The first part consists of 4 English letters. The first three digits of the code mainly describe the owner and operator of the container, and the fourth digit of the code describes the type of container.

The second part consists of 6 digits. It is the box registration code, which is used for the unique identification of a container box.

The third part is the check code, which is obtained by the first 4 letters and 6 digits of the number through the verification rules, which is used to identify whether an error occurs during the verification. That is, the 11th digit.

What are the common sizes and types of containers?

20GP, 40GP and 40HQ are the three most commonly used containers

What is the size and volume of 45HQ?

Known:
Length = 45 feet = 45 * 30.48cm = 13.716 meters

Width = 8 feet = 8 * 30.48 cm = 2.438 meters

Height = 9 feet 6 inches = 9.5 feet = 9.5 * 30.48 cm = 2.89 meters
Finally, you get:

The volume of the box of 45HQ = length * width * height = 13.716 * 2.438 * 2.89≈96CBM, and the actual cargo can be loaded is about 85m³.

Common containers and codes

1) Dry cargo box: box type code GP; 95 yards 42G1, mainly for the shipment of general goods, usually used to ship stationery, daily necessities, medicine, textiles, handicrafts, chemical products, Wujinjiaodian, electronic equipment, instruments and machine parts, etc.

2) Dry cargo high container: box type code GH (HC/HQ); 95 yards 45G1.
3) Garment on hanger: box type code HT; 95 yards 42V1; A container suitable for the shipment of apparel products.
4) Open top box: box type code OT; 95 yards 42U1, this kind of container does not have a roof, can be loaded and unloaded from the top by a crane, the top is covered with a tarp when loading, and its watertight requirements are the same as those of dry containers. It is suitable for loading objects with volume height, such as glass plates, etc.

5) Freezer: box type code RF; 95 yards 42R1, divided into external and internal two. The temperature can be adjusted between -28 °C ~ +26 °C, the built-in container can start the chiller at will during transportation, so that the container can maintain the specified temperature, and the external type must rely on the container special vehicle, ship and special yard, the station equipped with the freezer to refrigerate, this kind of box is suitable for transporting butter, chocolate, frozen fish, condensed milk, margarine and other items in summer.

6) Cold high box: box type code RH; 95 yards 45R1.
7) Tank tank: box type code TK; 95 yards 42T1, also known as liquid containers, is a special container made for the transportation of food, medicine, chemicals, and other liquid goods, and its structure is to fix a liquid tank in a metal frame.

8) Frame box: box type code FR; 95 yard 42P1, without a roof and sides, is characterized by loading and unloading from the side of the container. It is mainly used for overweight cargo, but it is also convenient for loading livestock, as well as naked cargo such as steel that can be exempted from outer packaging.

What is LCL, FCL?

LCL (Less than Container Load):

It refers to the goods of multiple shippers in a container, and the small batch of goods containing less than one FCL is LCL cargo, which is operated according to LCL cargo (LCL-LCL).

Full Container Load:

What are the big cabinets, small cabinets, and double backs? 

Large container generally refers to a 40-foot container, usually referring to 40GP and 40HQ. A 45-foot container is generally considered to be a special container.

A small container generally refers to a 20-foot container, usually referring to a 20GP.

Double backs refer to two 20-foot cabinets. For example, a trailer pulls two 20-foot cabinets at the same time; When the port is lifted, two 20-foot containers are lifted onto the ship at one time.

The life of the container 

The life of containers in the transportation industry is generally 10-15 years, and the eliminated undamaged container body still has good physical properties, and can generally be used for another 15 years after rust removal and paint treatment, and can be more durable if it is well maintained, or with other structures such as concrete. Of course, the new container is better in terms of appearance and performance.

Protection of containers 

The container material is affected by the physical properties of its own metal structure, the thermal insulation performance is poor, and the indoor thermal environment is relatively unstable, so it is necessary to set up a thermal insulation layer to effectively control the indoor thermal environment; In addition, the container body is prone to rust, and it is necessary to apply anti-rust paint to the inside and outside of the container to prevent corrosion. It should be noted that in order to prevent the spread of pests and diseases in international shipping, chromate, phosphorus or lead paints are used in container paints produced in some countries, so the original residual paint must be sanded off for some boxes to be used safely.
