What is a flat bar?

Flat steel refers to a type of steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular section and slightly rounded edges. It can be used as a finished product or as a raw material for welded tubes and thin plates for laminated rolling.

Flat steel is commonly used to make iron arches, tools, and mechanical parts, as well as for structural components of house frames and escalators in buildings.
