Low steel, also known as mild steel or carbon steel, is a type of steel that contains less than 0.2% carbon. It is a popular and cost-effective material used in a variety of industries, including automotive, construction, and manufacturing. However, its opposite, high steel, is a type of steel that contains a higher proportion of carbon, making it stronger and more durable. High steel is used in heavy construction projects, such as bridges and skyscrapers, as well as in the manufacturing of tools and machinery. While low steel is suitable for many everyday applications, high steel is necessary for more demanding and specialized projects.
