Bloom, billet, slab, plate, sheet, strip are terms used in metalworking and manufacturing. Blooms undergo first breakdown of ingots through hot working and have a large cross sectional area. Billets are further reduced through hot rolling. Slabs are hot rolled ingots with a specific cross sectional area and width. Plates are thick products over 6mm, while sheets are thinner but wide, and strips are thin and narrow. Blooms, billets, and slabs are considered semi-finished products.
