Hot Rolled Carbon Steel Sheet, Plate & Coil (HR Sheet / HR Plate / HRC)
As a premier global Hot rolled steel sheet supplier, Authentic Steel manufactures and exports high-grade Hot rolled carbon steel sheet and coiled steel plate products engineered for heavy-duty structural, manufacturing, and industrial engineering applications. Produced through continuous high-temperature rolling processes, our hot rolled steel products conform strictly to international standards, including ASTM A36, EN 10025 (S235JR / S355JR), and JIS G3101 (SS400).
Whether you require a standard mill-black finish, descaled pickled and oiled steel sheet (HRP&O), or anti-slip Floor Plate Coil/Sheet (chequered pattern), we deliver reliable inventory solutions featuring superior weldability, high tensile strength, and excellent formability.
High Mechanical Strength & Toughness: Excellent yield strength and fracture toughness, making it ideal for load-bearing structures, heavy equipment frames, and civil infrastructure.
Superior Weldability & Machinability: Low carbon equivalent ensures seamless arc, MIG, TIG, and submerged-arc welding without micro-cracking or requiring expensive pre-heating.
Versatile Surface & Finish Options: Available in raw mill-black scale, acid-pickled and oiled (HRP&O) for immediate laser cutting, or raised teardrop chequered patterns for safety decking.
Flexible Supply Formats: Supplied as flat cut-to-length sheets, heavy structural plates, or wide coiled steel plate for continuous roll-forming and high-volume stamping lines.
Full Compliance & MTC Support: Delivered with official EN 10204 3.1 Mill Test Certificates (MTC) verifying chemical heat analysis, mechanical tensile properties, and Charpy impact values.
Specifications & Technical Parameters
Our hot rolled steel inventory encompasses three specialized surface conditions tailored for downstream fabrication workflows:
Black / As-Rolled Finish: An economical choice for heavy structural frames, welded beams, and machinery chassis where mill oxide scale is acceptable.
Pickled and Oiled Steel Sheet (HRP&O): Acid-pickled to completely remove oxide scale and coated with protective rust-inhibitive oil, providing a smooth surface ideal for laser cutting, precision stamping, cold bending, and direct painting.
Floor Plate Coil/Sheet (Chequered / Diamond): Formed with raised teardrop patterns to maximize traction, wear resistance, and worker safety in heavy industrial environments.
Driven by exceptional mechanical toughness and versatile processing compatibility, our hot rolled steel plates and coils serve vital industrial sectors worldwide:
Building & Infrastructure: Structural I-beams, bridge girders, highway guardrails, transmission towers, and piling pipes.
Machinery & Heavy Equipment: Crane booms, excavator buckets, truck chassis, pressure vessel shells, and agricultural machinery housings.
Transportation & Industrial Flooring: Ship decks, dock platforms, warehouse walkways, and stair treads utilizing anti-slip Floor Plate Coil/Sheet.
Energy & Pipeline Transmission: Large-diameter welded API casing pipes, wind turbine towers, storage tank shells, and heavy flange components.
Every production batch undergoes comprehensive laboratory testing to guarantee structural reliability:
Tensile & Mechanical Testing: Yield strength, ultimate tensile strength, and percentage elongation verification.
Impact & Flaw Inspection: Charpy V-notch low-temperature impact testing and ultrasonic flaw detection (UT) for heavy thickness plates.
Dimensional & Chemical Inspection: Digital thickness tolerance monitoring, carbon equivalent (CEV) verification, and spectral analysis.
Mill Test Certificate (MTC): Issued in full compliance with EN 10204 3.1, supported by optional third-party inspections (SGS, Bureau Veritas, Intertek).
To streamline your downstream manufacturing, we provide comprehensive value-added processing services, including precision CNC laser/plasma cutting, custom slitting from coiled steel plate, surface shot blasting, and edge leveling. For long-distance maritime transit, all shipments receive heavy-duty export packaging: moisture-proof plastic film, anti-corrosive VCI wrapping, steel edge protectors, and high-tensile steel strapping mounted on seaworthy wooden pallets for safe ocean delivery.
