• Iron ore is mined worldwide and shipped to steel mills where it can be heated to over 2500 degrees.

  • The iron is seperated and processed into steel, while the molten waste is cast into pits.

  • Once cooled to a chilly 800 degrees, the slag rock is dug out and taken to a processing plant.

  • The slag is crushed and screened into a precise product.

  • The aggregate is quality tested and stockpiled in state approved categories.

  • The recycled aggregate is used in concrete, asphalt, and rock wool insulation. Slag is used as road base, construction backfill, in deicing agents, and as an agricultural liming product.

  • Instead of mining materials for infrastructure improvments, slag provides an environmentally sound, cost conscious and abundant source for any of your aggregate needs.
