Whether you plan to use cargo containers for portable storage, overseas shipping, or as temporary mobile offices, there are plenty of used cargo containers available for sale online. Many sellers offer delivery to your door as well as a chance to preview the container via online photos. By figuring out exactly what you need in a cargo container, you can narrow your search considerably from the start. In choosing cargo containers, here are a few attributes you’ll want to consider in advance: 1. Container strength and durability. What materials best suits your intended use? Are you looking for steel shipping containers or plastic storage containers? Or maybe a different kind of metal, like aluminum? It all depends on how strong you need the material to be and what your cargo is. 2. Dimensions: Consider size, weight, cubic capacity and desired shipping mode (air cargo, container ships, etc). Shipping containers for transporting cargo overseas must meet the standard dimensions required for shipping. Fortunately, dimensions are standard fare of online postings. Remember to compare both external dimensions and internal dimensions: Containers that have the exact same external dimensions may not have the same internal dimensions. And make sure that whatever you plan to ship does not exceed the recommended load volume for that cargo container. 3. Resistance to vandals, fire, wind and water. If the container is traveling overseas, it needs to be watertight, if it’s not meant to be so mobile, but instead used as a storage container in an unsavory part of town, then resistance to vandals is your top priority. Cargo insurance is a wise investment. 4.
