Clean Steels

Gerdau continues to make significant strides in sustainable steel cleanliness. By utilizing enhanced melt practice developments and strict process controls, Gerdau is producing bearing quality steels in its continuous casters. Gerdau recently expanded to a 240 mm bloom at its Monroe, Michigan mill, resulting in a greater reduction ratio, improved surface quality and cleaner steel with fewer inclusions. Gerdau is also investing more than $70.3M over the next three years to upgrade Monroe’s electric arc furnace and ladle refining technologies.
