First, most rebar produced in North America is produced using an EAF steel making process, or Electric Arc Furnace. Here, scrap steel is collected from various sources at the steel mill and put into a large ladle where the steel is then melted at temperatures up to 1,800° Fahrenheit. In this state, the molten steel will be poured into a casting.
