Steel Coils – The Fundamental Material for Industrial Manufacturing
Hot Rolled Coil (HRC) is a steel coil manufactured from continuously cast slabs or rough-rolled slabs through heating, rough rolling, finish rolling, and coiling processes. The product possesses excellent properties such as high strength, good toughness, ease of processing and forming, and good weldability.

- Key Differentiators
✔ End-to-End Supply Chain Advantage
We ensure full-process quality control. Using continuously cast slabs or pre-rolled slabs as raw materials, the products undergo processes such as furnace heating, high-pressure water descaling, rough rolling, finish rolling, laminar flow cooling, and coiling to guarantee stable product performance.
✔ Diverse Standards Coverage, Global Market Access
We support major global industrial standards, and our products comply with Chinese National Standards (GB), American Standards (ASTM), European Standards (EN), Japanese Standards (JIS), German Standards (DIN), and British Standards (BS). Whether the target market is North America, Europe, Southeast Asia, or the Middle East, we can provide products that meet local standards.
✔ High-Precision Dimensional Control
Adopting advanced rolling mills and automated control systems, ensuring thickness tolerances are strictly controlled within standard ranges.
- Quality Assurance
Hot-rolled coils: Localized oxidation discoloration is permissible, but defects such as cracks, scabs, and folds are prohibited.
Dimensional and Geometric Tolerances:
Thickness Tolerance: ±0.10 – ±0.17mm
Width Tolerance: +15/-10mm (1500mm width)
Flatness Requirements: Strict control of edge waviness.
International Certifications:
ISO 9001:2015 Quality Management System
CE Certification (EN Standard Products)
JIS Certification (Japanese Industrial Standard)
ASTM Certification (Meets US Standards)
BV/SGS Third-Party Inspection Agency Accreditation
EN 10204 3.1/3.2 Material Certificates Available
