Mild steel flat bar is a type of steel product that is rectangular in shape and has a flat surface. It is made from low carbon steel and is commonly used in construction, manufacturing, and industrial applications. Mild steel flat bars are versatile and can be easily welded, cut, and drilled to fit various requirements.

The low carbon content of mild steel makes it easier to work with than other types of steel, but also makes it less strong and durable. However, it is still a popular choice due to its affordability, availability, and ease of use. Mild steel flat bars are commonly used in the construction of frames, braces, and supports, as well as for making machine parts and in general fabrication. They are available in a variety of sizes and thicknesses to suit different needs.
