Hot rolled steel coils are a fundamental material in the steel industry, known for their versatility and cost-effectiveness. These coils are produced by heating steel above its recrystallization temperature and then rolling it into thin sheets or coils. This process enhances the steel's ductility and malleability, making it suitable for various applications across multiple industries. Hot rolled steel coils are characterized by their slightly rough surface texture and rounded edges due to the cooling process. They are typically used in situations where precise dimensions and surface finish are not critical, such as in construction, automotive frames, and machinery parts. The process also imparts less stress on the material, resulting in products that are easier to work with for further manufacturing processes like welding, forming, and cutting.
