“Manufacturing” From Refined Steel Material to Shaped Product The product may be intermediate, as in a rolled steel beam prior to “fabrication” The product may be final, as in a steel casting for a bridge saddle or a bollard. Two basic categories of manufactured steel products: Cast Steel Products made in one basic way in foundries Wrought Steel Products made one of several methods in mills: Forging Extruding Hot Rolling (with or without cold finishing) Casting is generally performed by pouring molten steel into sand molds. Casting is used instead of wrought methods when the steel product to be made is of such size and/or complexity that it is uneconomical to produce by these other methods.
