The most basic form of carbon steel is hot rolled steel. Hot rolled steel instantly recognizable by the bluish-tinge scale that covers the outside surface of a coil.
The scale is iron oxide that forms on the surface of the steel during a chemical reaction that occurs when the steel is created at a steel mill. Because of this scale, HR steel is best suited for use where the surface finish is not critical to the end user.
Because of hot rolled carbon steel’s versatility, it is used in a wide range of products. These include but are not limited to products in:
• Construction
• Shipbuilding
• Industrial machinery
• Truck equipment
• Tanks
• Pressure vessel tanks
• Farm equipment
• Dump bodies
• Containers
• Trailers
• Rail-car parts
• Metal buildings
• Platforms
• Guard rails
• Shelving products
• Waste equipment
