BLOOMS: A Semifinished product, usually in square (at times in rectangular) section of cross sectional size exceeding 5"x5" (125mm X 125mm). In some of the modern mills, the term bloom is used to cover such products of cross sectional size exceeding 8"x8". These are inputs for producing Heavy sections and Sheet piling section normally by hot rolling.
