Carbon steel rectangle bar A36 hot rolled is a versatile, low-alloy steel product commonly used in construction and manufacturing applications. It is characterized by its excellent weldability, formability, and moderate strength. Hot rolling is the process by which the steel is heated to a high temperature and then shaped into a rectangular bar, resulting in a stronger and more durable material. A36 steel bars are widely available in various sizes and are often used in structural components, machinery parts, and other applications where reliability and cost-effectiveness are essential.
