Raw steel production in the Great Lakes plunged from 575,000 tons the previous week to 547,000 tons last week and the capacity utilization rate trails 2014 by more than 10 percentage points so far this year.

Local steel output has been much lower than normal all year because of soaring imports that have seized a record-breaking 30 percent of the total market share. Overall U.S. production lags 2014 by 9 percent so far this year.

Great Lakes steel production fell by 28,000 tons, or 4.86 percent, in the week that ended Saturday, according to an American Iron and Steel Institute estimate. Overall U.S. steel output rose by just over 1 percent during the same period.

Most of the raw steel production in the Great Lakes region takes place in the Chicago area, mainly Lake and Porter counties. Indiana, which also has steelmaking operations in Fort Wayne and Crawfordsville, has led the nation in steel production for more than 30 years, largely because of the big mills on the Lake Michigan shoreline in the Calumet Region.

Nationally, domestic steel mills had a capacity utilization rate of 64.2 percent last week, down from 65 percent a week earlier. The capacity utilization rate had been a much more robust 74.6 percent at the same time a year earlier, but some industry analysts say it wouldn't be healthy unless it were over 90 percent.
