    Steel is strong, rigid, and has a low coefficient of thermal expansion. It is also heavy (multiple workers may be needed to transport it) and is subject to corrosion. Sometimes it is called carbon steel or black special steel to differentiate from stainless and galvanized steel. All steel, by definition, contains carbon.
