Nucor, Gerdau, and Optimus are raising rebar prices in the US

At least three major rebar producers in the U.S. have announced price increases, following the move previously announced by Commercial Metals Company (CMC). This is stated in letters from the companies to their customers, according to Kallanish.

Specifically, Nucor Bar Mill Group, Optimus Steel, and Gerdau Long Steel North America have raised prices on all rebar products by $30 per short ton. Additionally, Nucor and Optimus have introduced an extra surcharge of $20/ton on rebar in coils for new orders received after May 5.

The new terms apply to contracts not confirmed as of the end of business on Monday. However, previously agreed-upon orders remain protected under the old prices, provided they are shipped by May 18 for Nucor and Optimus and by May 17 for Gerdau.

Nucor noted that the company reserves the right to review and reevaluate offers that have not been officially confirmed. Optimus Steel emphasized that it will continue to monitor the market situation and adjust prices in line with changes in demand and costs.

Earlier, Commercial Metals Company implemented a similar increase, raising rebar prices by $30/t for new orders and introducing an additional surcharge of $20/t on products in bundles and coils.

As a reminder, Poland’s Cognor Holding raised rebar prices by nearly 20% starting in early 2026 amid a gradual market recovery and changes in the EU regulatory environment. The company expects these steps to partially offset losses from the weak 2025 and improve financial results in the coming quarters.
