Q235B Hot Rolled Carbon Steel Sheet Coil 1.2-20mm GB/T 700 Infrastructure Grade

Our Q235B Hot Rolled Carbon Steel Coil manufactured under GB/T 700-2006 specifications delivers reliable performance for India's massive infrastructure development programs. Q235B is the most widely used structural carbon steel grade across Asian markets, offering a balanced combination of strength (yield strength ≥235 MPa), ductility (elongation ≥26%), and excellent weldability that makes it ideal for large-scale construction projects, bridge engineering, and general structural fabrication. The material's low carbon content (C ≤0.20%) and controlled manganese levels ensure trouble-free welding with all standard electrodes and processes commonly used in Indian fabrication shops and construction sites.

Manufactured using advanced production techniques and rigorous quality control processes, our carbon steel coils deliver exceptional performance across diverse industrial applications. With an annual production capacity exceeding 500,000 metric tons, we maintain a robust supply chain that guarantees consistent availability and competitive lead times for bulk procurement. Our mills utilize state-of-the-art continuous casting and controlled rolling technology to achieve precise dimensional tolerances and superior surface finishes. Each coil is subjected to comprehensive mechanical testing including tensile strength analysis, yield strength verification, elongation measurement, and dimensional inspection before shipment.

• GB/T 700 Q235B Certified: Full compliance with Chinese national standard GB/T 700-2006 for carbon structural steels. Each shipment includes certified mill test reports showing chemical composition (C ≤0.20%, Mn ≤1.40%, Si ≤0.35%, S ≤0.045%, P ≤0.045%) and mechanical test results.
• India Infrastructure Ready: BIS (Bureau of Indian Standards) compatible specifications aligned with IS 2062 E250 grade. APTA Form E certificate available for preferential duty rates under Asia-Pacific Trade Agreement. Regular shipping to Nhava Sheva, Mundra, Chennai, and Kolkata ports.
• Extended Thickness Range: Available from 1.2mm for light structural applications up to 20mm for heavy civil engineering and infrastructure components, providing a single material solution across diverse project requirements.
• Cost-Effective Volume Supply: Competitive FOB and CFR pricing for bulk quantities with breakbulk vessel options for projects exceeding 500 MT, achieving 10-15% cost savings versus procurement through Indian trading intermediaries.
• Excellent Weldability Assurance: Carbon equivalent value (CEV) controlled below 0.38% ensures crack-free welding with E6013, E7018, and E71T-1 consumables without preheating for thicknesses up to 25mm, significantly reducing on-site fabrication costs.

Q235B structural steel coils form the material backbone of India's ambitious infrastructure development initiatives, including the Bharatmala highway program, Sagarmala port development, and Dedicated Freight Corridor projects. Primary applications encompass highway bridge structural components (girders, cross beams, bearing plates), railway bridge fabrication, industrial shed and warehouse frameworks, pre-engineered building (PEB) systems, transmission tower angle sections and base plates, solar panel mounting structures, water tank and silo fabrication, and general heavy structural fabrication in India's expanding network of MSME fabrication workshops. The material also serves the machinery manufacturing sector for agricultural equipment frames, crusher bodies, and conveyor systems, supporting the Make in India initiative's emphasis on domestic manufacturing capacity expansion.

These carbon steel coils are extensively utilized across heavy industry sectors where structural integrity and cost efficiency are paramount. The consistent mechanical properties across the entire coil length ensure reliable performance in automated stamping, roll forming, and CNC processing lines. End users benefit from reduced material waste and improved throughput compared to lower-grade alternatives. Our technical team provides complimentary application engineering support to help customers optimize material selection for their specific fabrication requirements, including formability analysis and welding procedure recommendations for South Asian market conditions.

Every coil is professionally packed with waterproof kraft paper, anti-rust oil coating, and galvanized steel strapping. Inner diameter protection rings and edge guards prevent transit damage. Standard coil orientation is eye-to-sky on wooden pallets with full plastic wrapping for maritime container shipping. Each shipment includes a detailed mill test certificate (MTC) documenting chemical composition, mechanical properties, and dimensional measurements. We maintain ISO 9001:2015 certified quality management systems with third-party inspection available upon request from SGS, Bureau Veritas, or TÜV. Our after-sales guarantee covers manufacturing defects, and our logistics team handles customs documentation including Form E, CO, and fumigation certificates for smooth import clearance in India and South Asia and beyond.
