Discover our primary selection of top-performing flat steel coils, processing sheets, wire materials, and structural products optimized for complex manufacturing demands.
Hansheng Technology (Hebei) Co., Ltd. is strategically located in Tangshan City, Hebei Province—widely recognized as the heart of China's heavy steel manufacturing and processing industry. Positioned within 150 kilometers of the major Tianjin international deepwater seaport and 150 kilometers from the capital metropolis of Beijing, our state-of-the-art facility commands an exceptional logistics and distribution network that ensures efficient, swift, and secure global shipping operations.
Established in 2006, we have transitioned from a localized steel mill into a comprehensive, highly integrated, export-oriented enterprise specializing in the production, finishing, and distribution of premium-quality steel products. Over nearly two decades of operation, our dedication to precision cold rolling, strict quality assurance, and localized regulatory compliance has made us a reliable manufacturing partner for industrial infrastructure worldwide.
All products are systematically manufactured to satisfy international quality regulations, including ASTM (USA), JIS (Japan), GB (China), DIN (Germany), EN (European Union), and AS/NZS (Australia/New Zealand).
Data-driven validation of our manufacturing infrastructure, global reach, and supply chain output capacity.
Certified with ISO9001:2000 & ISO14001, facilitating rigorous chemical verification and mechanical pre-shipment inspections for every batch.
Efficient shipping routes serving the Middle East, Southeast Asia, Central Asia, Europe, South America, and North America.
Providing customized rolling schedules, precision edge-trimming, custom surface oiling, and specialized packing classes (seaworthy packaging).
Underpinning the structural foundations of high-precision engineering, modern infrastructure, and low-carbon automotive technologies.
Cold rolled steel (CR) is a critical raw material for structural components requiring high tensile strength and deep-draw capability. Advanced High Strength Steel (AHSS) variants are extensively deployed to reduce vehicular weight, enhance structural crashworthiness, and optimize battery housing design for Electric Vehicles (EVs).
Cold-rolled sheets deliver exceptional dimensional control (tight thickness tolerances) and superb surface finishes (matte, bright, or custom textures). This makes them highly suitable for progressive die stamping, manufacturing of home appliances (HVAC, outer panels), and micro-tolerance electrical components.
Through secondary zinc, zinc-aluminum-magnesium, or pre-painted coating lines, cold-rolled substrates are converted into high-durability roofing, structural cladding, cable trays, and scaffolding systems designed to withstand highly corrosive marine and industrial atmospheres.
Unlike hot-rolled steel, cold-rolled steel is processed below its recrystallization temperature (typically at ambient room temperature). This introduces strain hardening, increasing yield strength by up to 20% and tensile strength by up to 15% while improving surface roughness (Ra) parameters. This difference prevents dimensional variations in high-speed automated robotic welding and stamping assemblies.

Thickness tolerances are held to ±0.02mm through continuous automatic gauge control (AGC) sensors integrated across our cold-rolling processing lines.
Available in Bright (b), Semi-bright (g), Dull (d), or Matte surface configurations, adjusted to meet customer coating, painting, or plating requirements.
Optimized annealing cycles (Batch or Continuous Annealing Lines) ensure uniform mechanical properties, reducing cracking and ear formation during deep-drawing.
Reviewing real-world applications and tailored steel solutions deployed to international markets.
Mitigating international trade risks through regulatory compliance and comprehensive testing.
We provide localized solutions, processing master coils into customized slit coils, precise sheets, or plates. Slitting limits are configurable down to 10mm wide strips, and cut-to-length sheets can be finished with strict flatness control using tension levelers.
To prevent rust and oxidation during maritime transit, we package coils using VCI (Volatile Corrosion Inhibitor) paper, high-density polyethylene film wrappers, and strong steel strapping with side protection rings.
We provide complete documentation required for import clearance, including Millennium Test Certificates (MTC) to EN 10204 3.1, Bill of Lading, Certificate of Origin, and third-party inspection reviews (SGS, Bureau Veritas).
Every shipping lot is subjected to destructive and non-destructive evaluation protocols: Yield Strength (Rp0.2), Ultimate Tensile Strength (Rm), Elongation (A80mm), Plastic Strain Ratio (r-value), Strain Hardening Exponent (n-value), Rockwell Hardness (HRB), and surface roughness mapping.
Supporting carbon emission reduction goals through smart manufacturing and energy-efficient cold-rolling processes.
Utilizing high-quality hot-rolled coils from EAF (Electric Arc Furnace) routes, helping reduce scope 3 carbon intensity for downstream OEMs.
