A "sea can" is a colloquial term used to refer to a shipping container. It is a large, standardized metal container primarily used for transporting goods via sea, rail, or road. Shipping containers are designed to be durable, secure, and capable of withstanding the rigors of long-distance transportation. They are constructed from corten steel, which is highly resistant to corrosion, and come in standard sizes, such as 20 feet or 40 feet in length. Shipping containers have standardized dimensions and are stackable, making them efficient for transportation and storage. Due to their durability and versatility, shipping containers are also used for various other purposes, including temporary or permanent storage, modular buildings, pop-up shops, and even as the basis for customized homes or offices.
