20ft High Cube Container
The 20ft High Cube shipping container combines the most popular container size (20ft general purpose) with an extra 1ft in height (9.6ft). These are for customers where the cargo or stored items are too tall for the general purpose container (8.6ft).
The age of a used container can vary considerably but usually they are sold by shipping lines after about 10 years of service.
Although some shipping containers are made of aluminium and steel, the majority are now made entirely of a rust-prohibitive steel called “Corten’’. A basic steel frame, fitted with weight-bearing castings fitted into the eight container corners, is filled in with corrugated steel panels which are between 1.5mm to 3.00mm thick. At one end is a pair of almost full width and height doors. These are normally fitted with four locking bars which interlock with the frame top and bottom. Most containers have a 27mm thick wooden ply floor which is supported on load bearing cross-bearers approximately 30cms apart, making the container capable of withstanding loads of 20 to 35 tons – depending on size.
A new container built by a reputable manufacturer will, under normal conditions, last 10 years without maintenance and continue for another 10- 20 years if serviced and maintained as advised.
The anticipated length of usage as a storage container depends on its condition at point of sale, the careful use and regular maintenance. Painting and servicing can prolong the life of a container.
