Storage Container Grades
What is a Container Grade?
Container grades provide an indication of the condition of any given container. These range from new builds straight from factory, to much older builds with some or many aesthetic blemishes and/or structural issues.
Whilst shipping containers are built to last for many years in harsh conditions, exposure to sun, rain, prolonged moisture and wind will eventually cause natural deterioration. They can also be damaged in transit or onsite by heavy machinery.
Unfortunately, there is not a universal shipping container grading standard that applies to all containers. However, larger suppliers have implemented a more objective and recognised grading system.
When you are considering a container for your own use, be sure to familiarise yourself with these grades when discussing price and availability.
Also be sure that the container supplier you end up choosing is not just grading containers based on what is available to them. For example, AA should be a new build container, not the best container that they have in their yard.
Master Container has an extensive image catalogue of individual containers. If you are not sure about what you are getting, ask our friendly team for some photos.
