Billet is a solid steel bar material used as raw material in the production of various steel products. It comes in standardized larger sizes and is commonly used in casting, rolling, or further processing into finished goods such as bars, plates, or other products that require high thickness and strength.

Bloom is a semi-finished steel product with a rectangular or square cross-section, larger than billets. It is primarily used as a raw material in the manufacturing of structural steel products. Blooms are commonly processed through rolling or forging to produce items such as beams, rails, and heavy-duty structural components that demand exceptional durability and strength.
