Domestic mills produced 1,831,000 short tons (st) at a capability utilization rate of 79.1% last week. That’s up 1.6% from 1,803,000 st a week earlier when capability utilization was 77.9%. And it’s an 8.2% jump from 1,692,000 st in the week ending April 4, 2025, when capability utilization was 75.6%.
Through April 4, adjusted year-to-date production stood at 24,028,000 st, at an overall capability utilization rate of 77.4%. That is a 5.2% increase from 22,835,000 st during the same period in 2025. At that time, the capability utilization rate was 76.1%.
