Steel bars are long, solid pieces of steel that are commonly used in construction and manufacturing. They come in various shapes, such as round, square, and rectangular, and are known for their strength and durability. Steel bars can be used to reinforce concrete structures, create frameworks for buildings, and manufacture machinery. These bars are produced through a process called steelmaking, where raw materials like iron ore and scrap metal are melted and shaped. Steel bars are often categorized by their grade, which indicates their quality and strength. They play a crucial role in ensuring the stability and safety of various structures and products.
