Steel prices continue to set new record highs week after week

Mar 18, 2021 · SMUs average price for steel plate in mid-March was $1,120/ton ($56.00/cwt). Plate prices dropped from around $1,000/ton ($50/cwt) in January 2019 to a low of $590/ton ($29.50/cwt) in August 2020. While it has recovered sharply like the flat-rolled products, the price of plate remains well below the price of sheet, which is highly unusual. Steel prices reach levels not seen since 2008
