Carbon steel sheet is one of the most versatile and widely procured forms of steel in global manufacturing. From automotive stampings and construction cladding to machinery housings and appliance panels, hot-rolled and cold-rolled carbon steel sheet delivers an unbeatable balance of strength, formability and cost. Huaxia-Steel supplies carbon steel sheet in commercial, drawing and structural grades to ASTM, EN, JIS and GB/T standards with full mill certification.
Product Overview
Carbon steel sheet is a flat-rolled product with thickness typically ranging from 0.3 mm to 6.0 mm. It is produced in two primary forms:
- Hot-rolled (HR) sheet: Formed above the recrystallization temperature, offering lower cost and good weldability. Slight scale remains on the surface.
- Cold-rolled (CR) sheet: Rolled at room temperature after pickling, delivering tighter thickness tolerance, smoother surface and higher strength. Ideal for exposed panels and precision stampings.
Huaxia-Steel stocks and mills carbon steel sheet in coils, slit strips and cut-to-length sheets to meet diverse fabrication schedules.

Surface Finish Options
- As-rolled (hot rolled): Mill scale surface; lowest cost; suitable for painted or galvanized applications
- Pickled and oiled (P&O): Acid-cleaned surface with protective oil; excellent paint adhesion and laser-cut edge quality
- Cold-rolled, skin-passed: Smooth, matte finish; ideal for exposed panels and electro-galvanizing substrate
- Cold-rolled, bright annealed: Highly reflective finish; for decorative and appliance applications
- Pre-painted (PPGI/PPGL substrate): Prime-coated coil ready for colour coating line
