The flat bar steel is rolled with negative deviation, but it is delivered according to the actual weight. The utilization ratio is 1-5 percentage points higher than that of the steel plate.

Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
