Many cans require opening by cutting the “end” open; others have removable covers. Cans hold diverse contents: foods, beverages, oil, chemicals, etc. Metal cans are not used as shipping containers. Steel cans are made of tinplate (tin-coated steel) or of tin-free steel. In some locations, even aluminium cans are called “tin cans”.
