This product is hot-rolled flat steel, made of high-quality carbon structural steel by hot rolling. It has a rectangular section with regular size, flat surface and uniform thickness. It features good bending resistance, compression resistance, and excellent weldability, cuttability and drillability. With high dimensional accuracy and no obvious defects such as cracks, slag inclusions or folds, it is widely used in steel structures, machinery manufacturing, frame supports, hardware parts, fences, bases, stamping parts and metal components, suitable for high requirements on strength, flatness and processability.<\/p>\n
