Nucor raised its consumer spot price for hot-rolled coil to $1,255 a short ton for the week of Oct. 19, up $15 and the fifth straight weekly increase. Four weeks earlier the number was $1,210. For anyone carrying a steel allowance on a job bought last spring, that’s the wrong direction at the wrong speed.
Steel Market Update reported the move Monday. California Steel Industries, Nucor’s West Coast affiliate, went up the same $15 to $1,320. Nucor is still quoting lead times of three to five weeks on hot-rolled, which is short next to what other mills are telling buyers.
Plate lead times pass the 2021 peak
SMU’s mid-October survey found average flat-rolled lead times running into mid- to late December, with some mills booking into 2027. Every sheet product except Galvalume is at its longest lead time since 2021. Plate is worse. Its lead times now sit above the 2021 peak, the high-water mark of the post-pandemic squeeze.
Then came the surcharge. Nucor Plate Group told customers Oct. 15 that its fuel surcharge doubles to $40 a ton on all shipments starting Nov. 1. It started at $10 in April, held there through August and moved to $20 in September. Nucor’s letter cited rising costs without saying which ones.
That $40 stacks on top of base price moves, including the $60-a-ton plate increase Nucor and SSAB announced earlier this month. Fabricators quoting plate girders, embeds, base plates or tank work for spring delivery are pricing a moving target.
Cleveland-Cliffs keeps a furnace running
Supply isn’t loosening on the integrated side either. Cleveland-Cliffs reported third-quarter net sales of $5.61 billion, up 18.5% from a year earlier, and net earnings of $152 million, its first profitable quarter since the second quarter of 2024. SMU attributed the turn to higher prices, more volume and trade policy that favors U.S. mills.
On its earnings call, Cliffs said it pushed the reline of the C blast furnace at Burns Harbor, Ind., from mid-2027 to April 2028. The furnace makes about 2.2 million tons a year. Keeping it hot through 2027 adds supply, but the reason given was that prices and demand are good enough to keep running. Mills don’t defer maintenance when they expect a soft market.
What steel prices mean for bids
Construction mostly buys hot-rolled indirectly. It shows up in HSS, cold-formed framing, metal deck and pre-engineered buildings, each a step or two downstream of the coil. Those suppliers price off coil with a lag, so the September and October run-up hasn’t fully reached their quotes. Exchange reported last week that construction input costs rose 11.9% in the year through September, with beam mills booked into spring 2027.
Three practical points follow. Price holds on steel-heavy packages are getting shorter. Escalation language tied to a published index is easier to defend than a fixed allowance. And schedule float matters as much as price: a December mill date is a February delivery once a service center and fabricator touch the material.
Nucor typically sets the plate surcharge around the 15th of each month for the next month’s shipments. The Nov. 15 letter is the next number to watch.
