What is a Conex Box
What is a Conex Box?
Conex Boxes are also known as shipping containers, and are the cargo containers that
allow goods to be stored for transport in trucks, trains and boats, making intermodal
transport possible. They are typically used to transport heavy materials or palletized
This type shipping term was referred to as Container Express and became to be
abbreviated as “ConEx.” Conex became universal and was later used to identify the
entire category of shipping containers. Connex is also an accepted spelling and can be
referred to as conex box, conex, conex container, connex box, conex boxes.
Conex is also referred to as shipping container, ISO container, conex box, railroad
container, intermodal container and certain truck trailers. This industry term refers to
the International Standards Organization (ISO), the largest developer of international
standards and the organization that developed the standard dimension specifications
for steel shipping containers used worldwide.
The design of the ISO standard containers allows for intermodal shipping, which is the
movement of containers from one mode of transport to another, like ship, rail, or truck,
without the need of having to load and unload, and reload its contents.
Conex Boxes are used to protect transported cargo from shock and bad weather
conditions, as well as keep storage products intact. They were first used in the 1950s
and were initially developed for the purpose of commercial shipping.
Depending on the type of product that is going to be sent, the Conex box can vary in
dimension, structure, material, etc. Characteristics of these shipping containers were
later standardized, something that expedited transport without the need to load and
unload the merchandise along the way.
There are different types of Conex Boxes for different types of transportation:
Common types include:
Dry Storage Conex Boxes
Refrigerated Conex Boxes
Open Top Conex Boxes
Flat Rack Conex Boxes
Open Side Conex Boxes
Tank Conex Boxes
Ventilated Conex Boxes

Now we are going to run through the essential parts of a conex box.
For a door to work, you need hinges. Pins hold the conex box's hinges together through
a barrel. In certain cases when doors are difficult to open, hinge pins and blades may
be seized due to corrosion.
Each door is fitted with 2 to 4 vertical lock rods to enable opening, closing and locking
of the doors.
The door handle rotates the lockbar to initiate the door opening process by forcing the
cams out of their keepers. Each door handle has a door locking handle retainer that
slides over the door handle when in locked position.
At the end of each lock rod is a cam welded in place which engages with knuckles, also
known as cam keepers. The action of engaging the cams to the keepers forms an antiracking function. In certain cases, often unfortunately too many, contents of the conex
box may have shifted causing conex box doors and lockrods to warp.
When opening a conex box, start with the right hand door first. Swivel the handles,
engage the cams and keepers, and twist both door handles. Closing the doors is just a
reverse of this process.
The lock box is a steel box welded to the right hand door which overlaps a staple welded
to the left hand door. A padlock, normally CISA type 285 66 can then be attached inside
the lock box through the staple and is then protected from direct attack, hindering
attempts to gain entry to the conex container.
ISO markings and a consolidated data plate allow worldwide intermodal transport and
are updated as necessary.
Take note that customs authorities in some countries may also have their own
container seal regulations as part of their national security.
Rubber gaskets are fitted to the container doors during the manufacturing process and
prevent water ingress. Door gaskets are designed to present two or more fins against
the structure or adjacent door. These are generally flexible but when the gasket is
damaged, they may become stiff thus jamming the door closed, or preventing it from
Conex boxes often take a beating, traveling around the world, being exposed to freezing
conditions and rust due to seawater or when the frost has melted.
