Steel prices in the market on September 15, 2025

Threaded steel: On September 15th, the average price of 20mm Grade III seismic resistant threaded steel in 31 major cities across the country was 3285 yuan/ton, an increase of 10 yuan/ton from the previous trading day. Recently, the production of rebar has decreased, consumption has rebounded, inventory continues to accumulate, and the fundamental contradiction between supply and demand has intensified.

Hot rolled coils: On September 15th, the average price of 4.75mm hot rolled coils in 24 major cities across the country was 3442 yuan/ton, an increase of 4 yuan/ton from the previous trading day. The speed of recovery in the manufacturing industry is relatively slow, and the overall downstream purchasing sentiment remains strong. Under the condition of accumulated inventory, steel mills' profits have suffered setbacks, and negative feedback risks still exist, suppressing spot prices.

Cold rolled coils: On September 15th, the average price of 1.0mm cold coils in 24 major cities across the country was 3956 yuan/ton, an increase of 5 yuan/ton from the previous trading day. The recovery of demand for "Golden September" is lower than market expectations, and resources are gradually arriving in the market. Merchants have lowered their expectations for the future, and are currently operating cautiously, with a focus on controlling inventory risks during shipment.

Medium thick plate: On September 15th, the average price of 20mm ordinary plate in 24 major cities across the country was 3536 yuan/ton, an increase of 2 yuan/ton from the previous trading day. Due to the maintenance and shutdown of several steel mills at the beginning of the month, the national production of medium and thick plates has decreased, and the market supply of circulating materials has not increased. However, market inventory has increased instead of decreased.
