Metal containers are sturdy vessels made from materials like steel or aluminum. They are commonly used for storing and transporting various items, including food, liquids, and industrial products. Their durability makes them ideal for both commercial and household use. These containers come in various shapes and sizes, such as cans, barrels, and boxes. They are often designed to be airtight or watertight, which helps preserve the contents and protect them from external elements.
