Scrap steel is recovered from automobiles, buildings and structures, railroad tracks, bridges, stadiums, ships, farm equipment and infinitely recycled to make these items again.
The most common way that SA Recycling purchases steel is as #1 HMS or #1 Heavy Melting Steel. The specificaiton for #1 HMS is for pieces that are cut to under 4’ by 2’ and are more than ¼” thick. If the item is larger than this specification the steel is purchased as Unprepared. This is usually for items like machinery, long pipe, beams and equipment that needs to be cut in order to be prepared to send it to steel mill to be re-melted.
