Hot - rolled carbon steel sheets are produced by rolling steel at high temperatures above its recrystallization point, which gives them good ductility and relatively low cost. In the construction industry, they are commonly used for structural components like beams, columns, and large - scale framing, providing the necessary strength and stability for buildings and bridges. The manufacturing of heavy - duty machinery, such as construction equipment, agricultural machinery, and industrial presses, also relies on hot - rolled carbon steel sheets for their robust mechanical properties and affordability. They are also utilized in the production of pipes, pipelines, and storage tanks, especially in applications where large - scale fabrication and cost - effectiveness are priorities.
