Hot Rolled Steel Coil (HRC) is a foundational flat steel product manufactured by heating steel slabs to high temperatures (1,100–1,250°C / 2,012–2,282°F) and continuously rolling them through a mill before coiling.
As a core material in global manufacturing, it is valued for its cost-effectiveness, excellent formability, and high production efficiency—making it indispensable across industries worldwide.
HR Steel Coil performance is defined by its physical and mechanical attributes, which vary by grade and application:
| Parameter | Standard Range | Typical Value for Common Grades |
|---|---|---|
| Thickness | 1.2 – 25.4 mm | 1.5 – 10 mm (general), 10 – 25 mm (heavy-duty) |
| Width | 1,000 – 2,500 mm | 1,250 mm (most popular), 1,500 mm |
| Yield Strength | 235 – 355 MPa | A36: 250 MPa; A572 Grade 50: 345 MPa |
| Tensile Strength | 370 – 550 MPa | A36: 400 MPa; A572 Grade 50: 450 MPa |
| Elongation | 20 – 35% | A36: 23%; A572 Grade 50: 21% |
| Surface Finish | Mill scale (bluish-black) | Pickled & Oiled (P&O) for smoother surfaces |
Popular HR Steel Coil Grade and Applications
| Grade | Key Features | Primary Applications |
|---|---|---|
| A36 | Low-cost carbon steel, excellent weldability, versatile | General construction, machinery parts, automotive chassis |
| A572 Grade 50 | High-strength low-alloy (HSLA), lightweight | Heavy construction, bridges, crane booms, vehicle frames |
| Q235B | Chinese standard, good plasticity, cost-effective | General fabrication, pipes, prefabricated buildings |
| SS400 | Japanese standard, consistent quality | General manufacturing, structural components, equipment housings |

HR Steel Coil Main Industrial Applications
- Construction: Structural beams, columns, steel frames, and concrete reinforcement.
- Automotive: Chassis parts, body panels, and wheel rims (often as a base for cold rolling).
- Machinery & Equipment: Gear housings, brackets, and heavy machinery components.
- Energy & Pipelines: Oil/gas transmission pipelines, storage tanks, and pressure vessels.
- Shipbuilding: Hull structures and marine-grade components (with corrosion-resistant treatments).
Exporting hot rolled steel coil (HRC) requires careful adherence to international standards, customs regulations, and documentation requirements.
As of 2021, many steel products (including HRC) no longer qualify for 13% VAT export rebates, as the Chinese government aims to reduce crude steel production and carbon emissions. Import tariffs vary by destination (e.g., 8% MFN rate for imports to China, 10–15% for the U.S., and 7–9% for the EU).
Some countries have start anti-dumping tarrifs on HR steel coil from China, The Anti-Dumping Committee of Indonesia (KADI) launched an anti-dumping (AD) sunset review on April 2, 2026, regarding hot-rolled coil (HRC) imports from China.
This investigation, focusing on HS code ex 7225.30.90, responds to a request from PT Krakatau Posco and other local producers. Current evidence points toward recurring dumping practices that cause ongoing damage to the domestic industry.
This legal process follows a 2022 decision to impose AD duties between 4.2% and 50.2% for five years. KADI aims to determine if these measures must remain to prevent further market harm.
The review will conclude within 12 months, as officials evaluate the potential for continued dumping of Chinese HRC containing 0.0008% to 0.003% boron and/or 0.025% or less titanium.
