Steel Plate
The OSM Rolling Mill at OSM Portland Steelworks produces over 500 grades and specifications of steel plate and is known for its ability to provide products and services that consistently satisfy our customers' expectations.
Our plate products span a wide variety of grades and sizes of hot-rolled plate, strip mill plate and heat-treated plate.
We produce as-rolled carbon, high-strength-low-alloy and alloy grades, plus heat-treated carbon and alloy grades.
Heat-treated plate is available from the OSM Rolling Mill in the quenched and tempered, normalized or process annealed condition.
Our ability to turn and roll product to width before we finish the length allows us great flexibility in producing our customers' specific dimensions.
Steel plate is used to produce railcars, barges, ocean-going vessels, industrial equipment, large diameter pipe for oil and natural gas transmission, wind towers, bridges, and many other applications.
