Two Basic Types of Slag
Stein supplies the two basic types of slag used today: Blast Furnace Slag and Steel Slag. Blast Furnace Slag is the co-product of iron making in a blast furnace, while Steel Slag is a co-product of steel making in a BOF (Basic Oxygen Furnace) or EAF (Electric Arc Furnace).

Blast furnace slag is used in a variety of applications including structural concrete, mineral wool, and glass manufacture. Steel slag also has numerous applications, such as an efficient non-slip choice for asphalt pavement where friction is desirable. All slag is crushed, screened and graded to specific sizes. Experts at processing slag, Stein delivers the right size and quality of slag for their customer's needs whether slag is needed for a road base shoulder or for a fire resistant masonry wall.
