Authentic Steel is the export department of Winroad Group and a professional manufacturer and exporter of prime standard commercial hot rolled coils (HRC). From our production hub in Tianjin, China, we supply mill-direct commercial carbon steel coils to engineering contractors, steel pipe manufacturers, service centers, and distributors in 78+ countries. We provide mill-direct pricing, custom processing, and rapid export dispatch through Tianjin Port. Our commercial HRC can be supplied to international specifications on request.
Commercial hot rolled coils are known for high versatility and stable mechanical properties. According to our brochure, standard grades include:
Q195
Q235B
Q345B
Q355B
SS400
ASTM A36, etc.
SS400: General structural steel widely used for general fabrication, container construction, and machinery components.
ASTM A36: North American benchmark carbon structural steel, recognized for good tensile strength and structural reliability under heavy loads.
Q235B: Chinese standard structural steel, providing cost-effective material solutions for mass structural applications.
Higher grades such as S235JR, S355JR, and S275JR are available on request. Please share your target application and mechanical requirements so we can recommend a suitable specification.
According to our company brochure, the standard HRC range is:
Thickness: 0.8–19 mm
Width: 900–2000 mm
Length: 1000–12000 mm or as needed
Coil weight: 5–25 MT
Surface: as-rolled (black surface); checkered available
Edge: mill edge or slit edge available on request
Coil inner diameter: 508 / 610 mm available on request
Custom slitting, cut-to-length, and other processing options are available on request. A Mill Test Certificate (MTC) can be supplied on request.
Steel pipe and tube manufacturing: ERW, LSAW, SSAW welded pipes, structural hollow sections, and water transmission lines
Construction and infrastructure: structural framing, I-beams, H-beams, channel steel, bridge girders, and building frames
Machinery and transport equipment: chassis panels, agricultural machinery bodies, heavy equipment frames, and container flooring
Stamping and metal fabrication: brackets, flange rings, container corner fittings, and pressed structural components
Authentic Steel operates coil processing facilities equipped with precision slitting lines, roller leveling machines, and cut-to-length equipment. Whether you require narrow HRC slit strips for tube mills or flattened cut-to-length carbon steel plates, our technical team supports exact dimensional tolerances and flat surface profiles. Every shipment undergoes quality inspections, including yield testing, dimensional tolerance checks, and chemical composition analysis. Additional testing is available on request.
Every batch undergoes laboratory inspection, including chemical composition analysis, tensile and yield strength verification, and surface checks. Charpy impact testing and ultrasonic flaw detection are available on request. A Mill Test Certificate (MTC) can be supplied on request, and third-party inspection is available on request.
To reduce transit rust, surface scratches, and edge damage during ocean transport, our HRC coils use multi-layer export packaging: rust-inhibiting VCI paper, plastic moisture barriers, metallic corner protectors, and high-tensile steel banding on heat-treated wooden skids or pallets. This packaging is suitable for long-distance container shipment and safe unloading.
