The IAA type container is a 40-foot dry cargo container with a content of up to 67.96m3. The general deadweight is 3800kg, the deadweight is 26.68 tons, and the total deadweight is 30.48 tons. The IC type is a 20-foot container with an internal volume of 33.2m3. The deadweight is generally 2317kg, the deadweight is sub 17.9 tons, and the total deadweight is 20.32 tons.

Container type:

There are REEFER CONTAINER, abbreviation RF, DRESS HANGER CONTAINER, OPEN TOP CONTAINER abbreviation OT, FLAT RACK CONTAINER abbreviation FR, tank container (TANK CONTAINER) abbreviation TK , Refrigerated containers, platform containers (PLATFORM CONTAINER), ventilated containers (VENTILATED CONTAINER), insulated containers (INSULATED CONTAINER). The open-top container is used to load heavy goods such as glass plates, steel products, machinery, etc., which can be loaded and unloaded from the top by a crane.

A canned container is a container composed of a bottom surface of a box, a tank body and a surrounding frame, and is suitable for liquid cargo.

Container size:

Maximum length, width, and height inside the container. The height is the distance from the bottom surface of the box to the bottom of the top plate, the width is the distance between the two inner liners, and the length is the distance from the inner panel of the door to the inner liner of the end wall. It determines the internal volume of the container and the maximum size of the cargo in the container.

What do GP, HQ, OT, FR, HT, RH, GP/DC mean?

The common ones are GP/DC which refers to dry containers. There are many types of special containers, mainly divided into: Reffer Container, Dress hanger Container, Tank Container, Open Top Container) and Flat Rack Container (Flat Rack Container) to meet the special needs of special groups.

1. GP (flat cabinet): GP stands for General Purpose (Containers), which is generally called a flat container. For example, 40GP refers to a 40-foot ordinary container.

2. HQ (high cabinet): HQ stands for High Cube (containers). For example, 40HQ refers to a 40-foot tall container; the difference between the two is that HQ is higher than GP.

3. OT (Open Top Cabinet): OT is the abbreviation of Open Top, which refers to an open top cabinet, that is, a cabinet with no top of the box but a tent on the top of the box. OP (OPEN TOP), can be loaded on top, suitable for super large cargo such as machinery.

4. FR (frame cabinet): FR stands for frame container. This kind of container has no top plate and no left and right side plates around, only front and rear plates, corner posts and front and rear roof beams. At the same time, the front and rear plates are foldable, and the floor is folded. As a whole, it looks like a flat panel, so the Guangdong area is often called "flat cabinet". In addition, the floor of this kind of container is very thick, and the overall weight is heavier than that of ordinary containers. It is mainly used to install large-scale machinery. FR (FLAT RACK), specially designed for heavy cargo loaded from the top or both sides. The frame cabinets are mainly loaded for the transportation of large-scale machinery and equipment with ultra-long, ultra-wide, and ultra-high weights and the transportation of heavy-weight bulky goods. Such as heavy machinery, steel, wood, etc., specifically ball mills, tower cranes, elevators, steam turbines, generators, pile drivers, boilers, tower cranes, condensers, sugar equipment, etc.

5. HT (Dress hanger Container): As the name suggests, this is specially used to hang clothes. There are many crossbars on the upper side beam of this container, and each crossbar has several bars. Belt buckles, nylon buckles or ropes use the hooks on the hangers to hang clothes directly on the buckles or ropes.

6. RH (High Freeze Refrigerator) refrigerated containers mainly load goods: food: meat, fish, aquatic products, biscuits, chocolate, chemical products: mainly fine chemical products; such as perfume, air freshener, and plastic products.

7. RF (Freezer) Reffer Container: In international practice, the appearance of the freezer is white, which is set by the principle of black heat absorption and white constant temperature. The freezer parameters are divided into 20-foot freezer: external dimensions 6058*2438*2438 (mm), internal dimensions 5391*2254 (mm), nominal height 2130mm. The volume is 25.9, the dead weight is 2750kg, the total weight is 24000kg, and the load is 21250kg. 40-foot freezer: external dimensions 12192*2438*2591 (mm), internal dimensions 11480*2235 (mm), nominal height 2235mm. The volume is 57.3, the dead weight is 4750kg, the total weight is 30480kg, and the load is 25730kg.

8. TC (Tank Container): also known as liquid container. It is a special container manufactured for the transportation of liquid goods such as food, medicine, and chemicals.
