A steel can, tin can, steel packaging, or can is a container for the distribution or storage of goods, made of thin metal. Many cans require opening by cutting the "end" open; others have removable covers. They can store a broad variety of contents: food, beverages, oil, chemicals, etc. Steel cans are made of tinplate (tin-coated steel) or of tin-free steel. In some dialects, even aluminium cans are called "tin cans". Most cans are right circular cylinders with identical and parallel round tops and bottoms with vertical sides. http://www.gscustomize.com/tin-cans/
