Heavy Melting Scrap
Heavy melting scrap (HMS) is a designation for recyclable steel and wrought iron. It is broken up into two major categories: HMS 1 and HMS 2, where HMS 1 does not contain galvanized and blackened steel, whereas HMS 2 does.
Shredded Scrap
The shredded scrap grade consists of homogeneous iron and steel scrap, which is magnetically separated, originating from automobiles, including but not limited to unprepared no. 1 and no. 2 steel, miscellaneous baling, and sheet scrap. For shredded scrap, the average density ranges from fifty (50) pounds per cubic foot, to seventy (70) pounds per cubic foot, as specified by the Institute of Scrap Recycling Industries.
Railroad Ferrous Scrap
Obsolete ferrous scrap is recovered from automobiles, steel structures, household appliances, railroad tracks, ships, farm equipment, axles, rail joints, rail road cars and other sources.
