The high strength steel flat bar is a rectangular-section steel product designed for applications requiring stability, strength, and workability. It is made from carbon structural steel or low-alloy structural steel and undergoes strict dimensional control, offering flatness, straightness, and consistent thickness across the full length.
This type of flat bar is especially popular in engineering and manufacturing environments that require components to be cut, welded, bolted, or formed with precision.
