Steel Bloom

Steel blooms are large-format semi-finished products (150×150mm to 400×400mm cross-sections) used as raw material for heavy structural sections, industrial beams, and large rebar. Manufactured via continuous casting or rolling, these high-strength carbon/alloy steel products offer exceptional mechanical properties and dimensional stability for demanding applications in construction, shipbuilding, and heavy machinery.

Steel Blooms are semi-finished steel products, typically produced with square or rectangular cross-sections. They serve as a fundamental raw material in manufacturing larger steel components, including beams, rebar, and structural sections. These products play a crucial role in the production of structural steel and are widely utilized in various industrial applications. Produced from carbon steel or alloyed steel, Steel Blooms are highly valued for their superior mechanical properties, excellent formability, and versatility across diverse industries. They find extensive use in construction, automotive, and energy sectors.
