The HRC MS HR 0.3mm Q235D Hot Rolled Carbon Steel Coil is a versatile low-carbon steel product manufactured through the hot rolling process. Available in grades such as Q195, Q215, Q235, Q255B, Q275, and ASTM A36/ST37 equivalents, this steel coil offers excellent weldability, formability, and mechanical strength.

Designed for industrial fabrication, shipbuilding, boiler manufacturing, pressure vessels, structural components, and flange production, the product supports multiple processing methods including bending, welding, cutting, punching, and decoiling. With customizable thicknesses, widths, and lengths, it meets the demands of diverse engineering projects worldwide.

Many industries face challenges when sourcing carbon steel materials:

• Inconsistent material quality affecting fabrication performance
• Limited dimensional options for customized projects
• Poor weldability leading to production inefficiencies
• Delayed deliveries impacting project schedules
• Surface defects causing premature corrosion and wear
• Difficulty finding a single material suitable for multiple applications

These issues can increase manufacturing costs and reduce operational efficiency.

Our Hot Rolled Carbon Steel Coil provides a reliable and cost-effective solution:

• Manufactured from high-quality carbon steel grades
• Excellent strength-to-cost ratio
• Superior welding and forming performance
• Custom dimensions available according to project requirements
• Coated surface options for enhanced durability
• Suitable for heavy-duty industrial and structural applications
• Fast production and delivery support

The result is a versatile steel material that improves fabrication efficiency while maintaining long-term performance.

Used in machine frames, equipment housings, and fabricated components.

Suitable for cutting, bending, welding, and customized metal processing.

Hot rolled carbon steel coil is produced by heating steel billets above their recrystallization temperature and passing them through rolling mills.

1. Steel billets are heated to high temperatures.
2. The heated steel passes through rolling stands.
3. Thickness and width are reduced to required dimensions.
4. The material is cooled under controlled conditions.
5. Surface treatment and coating are applied if required.
6. The finished steel is wound into coils or cut into plates.

This process improves production efficiency while maintaining excellent mechanical properties and workability.

Selecting the right carbon steel coil depends on application requirements.

• Q195/Q215: Suitable for light fabrication and general forming.
• Q235: Most popular grade for structural applications.
• Q275: Higher strength requirements.
• ASTM A36/ST37: International structural steel projects.

• 0.1mm–2mm: Light fabrication and sheet applications.
• 2mm–6mm: General industrial manufacturing.
• 6mm–20mm: Structural and heavy-duty applications.
• 20mm+: Pressure vessels, shipbuilding, and engineering projects.

• Standard hot rolled surface
• Coated surface for improved corrosion resistance

If welding, bending, or punching is required, Q235 and ASTM A36 grades are typically preferred due to their excellent machinability.

Q235 is a Chinese standard carbon structural steel, while ASTM A36 is the American equivalent. Both offer similar strength and weldability for structural applications.

Yes. Thickness, width, and length can be customized according to project requirements.
