MK-OBL ISO Corner Casting,Top Left

 Shipping containers are standardised according to ISOstandards such as ISO 668, 1496, ...From a structural point of view, a container consists ofa strong frame at the front side and a strong frame witha door at the aft side. Each of these frames is composedof 2 vertical corner posts, 2 horizontal girders atthe bottom and on top, and 4 corner castings (2 at the bottom, 2 on top, see also MK-0). These elements are

designed to take all the external loads working on thecontainer.The rest of the container (roof, longitudinal walls, andbottom) is not taken into account for securing calculations  because these elements are weak in comparison 

to the end frames. Only for special, by the classification society defined, cases may the strength of these longitudinal elements be taken into account for the securing 

calculations. Containers can be secured to a foundation or to eachother y connecting elements fitting into the ISO-holes ocated the underside of the bottom corner castings and in the upper side of the top corner castings. 

Containers can be additionally secured of stiffened by 

lashing elements fitting into the standardised front and 

side openings of the top and bottom corner castings.
