Standard containers are also known as general purpose containers They are closed containers, i.e. they are closed on all sides. A distinction may be drawn between the following types of standard container: Standard containers with doors at one or both end(s Standard containers with doors at one or both end(s) and doors over the entire length of one or both sides Standard containers with doors at one or both end(s) and doors on one or both sides In addition, the various types of standard container also differ in dimensions and weight, resulting in a wide range of standard containers. Standard containers are mainly used as 20' and 40' containers. Containers with smaller dimensions are very seldom used. Indeed, the trend is towards even longer dimensions, e.g. 45'.
High-cube containers are similar in structure to standard containers, but taller. In contrast to standard containers, which have a maximum height of 2591 mm (8\'6"), high-cube containers are 2896 mm, or 9\'6", tall. High-cube containers are for the most part 40\' long, but are sometimes made as 45\' containers. A number of lashing rings, capable of bearing loads of at most 1000 kg, are mounted on the front top end rail and bottom cross member and the corner posts. Many 40\' containers have a recess in the floor at the front end which serves to center the containers on so-called gooseneck chassis. These recesses allow the containers to lie lower and therefore to be of taller construction.

The walls of open-top containers are generally made of corrugated steel. The floor is made of wood. It has the following typical distinguishing structural features. The roof consists of removable bows and a removable tarpaulin. The door header may be swivelled out. These two structural features greatly simplify the process of packing and unpacking the container. In particular, it is very easy to pack and unpack the container from above or through the doors by crane or crab when the roof is open and the door header is swivelled out. It should be noted, however, that the purpose of the roof bows of an open-top container is not solely to support the tarpaulin but also to contribute to container stability. Flatracks are therefore more suitable for overheight cargoes. Lashing rings, to which the cargo may be secured, are installed in the upper and lower side rails and the corner posts. The lashing rings may take loads of up to 1,000 kg. Usual open-top container dimensions are 20' and 40'.

Flatracks consist of a floor structure with a high loading capacity composed of a steel frame and a softwood floor and two end walls, which may either be fixed or collapsible. The end walls are stable enough to allow cargo securing means to be attached and several flatracks to be stacked on top of one another. Flatracks are available in 20\' and 40\' sizes. A number of lashing rings, to which the cargo may be secured, are installed in the side rails, the corner posts and the floor. The lashing rings may take loads of up to 2000 kg in the case of 20\' flatracks or up to 4000 kg in the case of 40\' flatracks. Some types of 20\' flatracks have forklift pockets. 40\' flatracks have gooseneck tunnels at each end. In addition, they are sometimes equipped with lashing winches with 2 metric ton lashing belts. For transport of certain cargoes, flatracks may be provided with stanchions.

Platforms consist solely of a floor structure with extremely high loading capacity; they have no side or end walls. This high loading capacity makes it possible to concentrate heavy weights on small areas. A platform consists of a steel frame and a wooden floor structure. Platforms are available in 20' and 40' sizes. 40' platforms have a gooseneck tunnel at each end. Lashing rings, to which the cargo may be secured, are installed in the side rails. The lashing rings may take loads of up to 3.000 kg.

The refrigeration unit is arranged in such a way that the external dimensions of the container meet ISO standards and thus fit into the container ship cell guides, for example. The presence of an integral refrigeration unit entails a loss of internal volume and payload. When being transported by ship, integral units have to be connected to the on-board power supply system. The number of refrigerated containers which may be connected depends on the capacity of the ship\'s power supply system. If the aforesaid capacity is too low for the refrigerated containers to be transported, "power packs" may be used, which are equipped with relatively large diesel generators and satisfy ISO requirements with regard to the dimensions of a 20\' container. When at the terminal, the containers are connected to the terminal\'s power supply system. For transport by road and rail, most integral unit refrigeration units are operated by a generator set (genset). This may either be a component of the refrigeration unit or connected to the refrigeration unit. Air flows through the container from bottom to top. In general, the "warm" air is drawn off from the inside of the container, cooled in the refrigeration unit and then blown back in the container as cold air. To ensure adequate circulation of the cold air, the floor is provided with gratings. Pallets form an additional space between container floor and cargo, so also forming a satisfactory air flow channel. In addition, the side walls of the container are "corrugated", which ensures satisfactory air flow there too.
TBulk (or bulk cargo) containers have three loading hatches in the roof, each of a diameter of approx. 455 mm (1 3/4\'). The distance between the hatches (center to center) is 1.83 m (6\'). On the door side, there are two discharge hatches, which are sometimes equipped with short discharge tubes for guiding the bulk cargo. Alternatively, two unloading hatches may be mounted in the doorways, for emptying the containers. Such containers may also be used for general cargo. Lashing rings are mounted in the top side rails for securing the cargo. Some bulk containers are equipped with forklift pockets, which allow handling by forklift trucks.
Tank containers must be at least 80%% full, to prevent dangerous surging of the liquids in transit. On the other hand, they must not as a rule be over 95%% full, or there will not be sufficient ullage space for thermal expansion. The extent of thermal expansion may be calculated for each cargo on the basis of the following formula: ΔV = Va · γ · ΔT Ve = Va (1 γ · ΔT) ΔV : change in volume Va : volume at initial temperature a Ve : final volume at temperature e γ : coefficient of cubic (thermal) expansion ΔT : temperature difference in degrees kelvin Tank containers intended for transporting foodstuffs must be labeled "Potable Liquids only". Some hazardous materials must be transported in tank containers with no in- or outlet openings below the surface of the liquid. Tank containers are generally designed for an operating pressure of up to 3 bar (above atmospheric). The test pressure used is 4.5 bar (above atmospheric). If the cargo requires temperature-controlled transport, tank containers can be equipped with insulation or heating. The temperature of the cargo may be precisely controlled using temperature sensors.
Containers are used in the supply chain to transport large shipments, bulky goods, and heavy items: unpackaged; in lightweight blocks; packed. They are also in demand in modular construction, where they may be used to build large warehouses, industrial buildings, and agricultural facilities. The container is flexible and cost-effective due to the fact that it is equipped with all of the specific gripping components required for dealing with professional loading systems
