Recently, with the steady progress of industries such as infrastructure and the automotive sector, market demand for hot-rolled steel coil has continued to rise. As a key product in the steel industry, hot-rolled steel coil, due to its high strength and excellent toughness, is widely used in various fields. Its materials and sizes are suitable for different applications, making it an indispensable basic material in industrial production.
Recently, hot-rolled coil prices in North China have fluctuated, with the national average price increasing by 3 yuan/ton week-on-week. Prices have declined slightly in some regions. With the traditional peak season of "Golden September and Silver October" approaching, market expectations for a price rebound are strong. Hot-rolled coil prices are expected to remain volatile in the short term, driven by a balance of bullish and bearish factors. The impact of supply and demand, policy guidance, and international developments on prices remains to be closely monitored.
Hot-rolled steel coils are available in a wide range of materials, with mainstream grades including Q235, Q355, and SPHC. Among them, Q235 is a common carbon structural steel with low cost and good plasticity, suitable for building steel structures, bridge components, and general machinery parts. Q355 is a low-alloy, high-strength steel with higher strength than Q235, suitable for applications requiring strength, such as construction machinery and vehicle frames. SPHC is a hot-rolled, pickled steel with excellent surface quality, often used as raw material for automotive parts and home appliance housings.
Material differences determine the application of hot-rolled steel coils. Q235 steel coils, due to their high cost-effectiveness, are often used in load-bearing brackets and container bodies in civil construction. Q355 steel coils, with their excellent mechanical properties, are a core material for wind turbine towers and heavy truck chassis. SPHC steel coils, after subsequent processing, can be made into fine components such as automotive doors and refrigerator side panels, meeting the aesthetic and precision requirements of consumer products. Furthermore, some hot-rolled steel coils made of specialized materials are also used in oil pipelines, shipbuilding, and other fields.
Hot-rolled steel coils have clear standard dimensions. Thicknesses typically range from 1.2mm to 20mm, with common widths of 1250mm and 1500mm. Custom widths are also available upon request. The inner diameter of the coil is typically 760mm, while the outer diameter ranges from 1200mm to 2000mm. Unified size standards facilitate cutting and processing for downstream companies, improving production efficiency and reducing adaptation costs.
