Most manufacturing and wholesale enterprises have huge amounts of stock which they have to store carefully for a considerable amount of time. Transportation of large quantities of materials will also have to be undertaken during trade. So there is a need for big containers.
Some people have made it a business, collecting used containers, replacing broken parts, painting them and putting them up for sale. These boxes are also tested to see if they are air tight and can withstand specific weather conditions. Some dealers also offer to customize these containers according to the needs of the buyer.

Choosing the container will depend upon the nature of goods to be transported or stored. Some require heavy steel or aluminum types whereas in some cases plastic boxes will suffice. Before buying a used container, make sure that your material does not exceed its recommended volume for storage.
This is especially important if you intend to ship your stock to distant places. In such cases, the container should be checked to see if it is water tight. If it is to be kept in some deserted storehouse, it should have proper locks and safety catches to protect against looters.
The main intention of going for a used container is obviously the price. You can expect to save up to 30-50% with them. Lower priced ones will not carry any warranties whereas those priced higher may offer some limited warranties and customization options.
