  • More than 70% of containers are made up of steel.

Advantages of containerization

  • They are cheap in price.
  • They can be more easily repaired, compared to aluminum GRP containers
  • They can resist damage.
  • Cost due to loss or damage of goods is reduced.
  • Lower labor cost due to automated material handling equipment
  • Lower warehousing & transportation cost, since containers are easily stored & transported.
  • Containers can also be used for temporary storage at ports with limited warehousing facility.

  • Reduction in marine insurance premium
  • Retention of the original quality of goods.
  • Faster and reliable delivery

  • They have more tare weight thus carry less pay load.
  • They suffer from corrosion
  • They required sophisticated handling techniques.
  • Lack of facility at donors & other suppliers premises

Classification of containers in terms of their measurement

  • ISO has classified standardization of containers in multiple of 10 ft. i.e. 10 ft., 20 ft., 30 ft., 40 ft. etc.
  • Predominantly 20 ft. & 40 ft. containers are mostly used around the world.
  • 65% of world fleet consists of 20 ft. containers.
  • 20 ft. containers are referred to as Twenty Feet Equivalent Unit or TEU.
  • This is commonly used term all over the world
  • It becomes easier for container terminal operator (CTO) & ship owner to estimate the space required in a container.
  • Most of the containers have a width of 8 ft., but in height, containers vary from 8 ft. to 8-1/2 ft.
  • Presently, 75% of the containers have the height of 8-1/2 ft.
  • The inside volume of the containers of size 20 ft. (8 ft.*8-1/2 ft.) is about 35 cubic meter.
