At Authentic Steel, we supply and export top-grade Full Hard Cold Rolled Coils (FH CRC) engineered to meet the demanding technical standards of continuous coating lines and specialized metal forming operations. Full hard cold rolled steel is produced by cold-reducing pickled hot-rolled substrate through multi-stand tandem mills without undergoing the final annealing process. Because it bypasses the final annealing step, FH CRC remains in a work-hardened condition, offering high hardness, elevated yield strength, and low elongation. This makes it an ideal cost-effective substrate for subsequent galvanizing, galvalume processing, and direct roll forming. As the dedicated export arm of Winroad Group, we supply ISO 9001-certified full hard coils to steel coaters, tube mills, and profilers across more than 78 countries.
Our full hard cold rolled steel coils are produced under strict metallurgical control to ensure consistent thickness tolerances, flat strip profiles, and uniform surface cleanliness:
Material Grades & Standards: JIS G3141 SPCC (Full Hard equivalent), EN 10130 DC01 (unannealed / Full Hard equivalent), ASTM A1008 Full Hard, and GB/T 5213 Q195/Q235 (Full Hard). Availability should be confirmed per order.
Mechanical Hardness: Typical hardness of HRB 85–95 or HV 170–210 depending on grade and thickness; actual values are confirmed in the Mill Test Certificate.
Thickness Range: 0.12 mm – 2.0 mm (specializing in ultra-thin to standard gauges)
Coil Widths: 600 mm, 914 mm, 1000 mm, 1220 mm, 1250 mm (precision narrow slitting available)
Surface Condition: Dull finish (SD) or Bright finish (SB); lightly oiled, medium oiled, or unoiled/dry
Edge Type: Mill edge or precision slit edge
Certifications: ISO 9001 quality system; complete EN 10204 3.1 Mill Test Certificates (MTC) supplied with every batch
Featuring high tensile strength and superior surface flatness, full hard cold rolled coils serve as critical feedstocks across several key manufacturing industries:
Galvanizing & Coating Substrate: The premier raw material input for continuous hot-dip galvanizing (GI), galvalume (GL), and prepainted steel (PPGI) production lines equipped with in-line annealing furnaces.
Roll Forming & Roofing Fabrication: Used for manufacturing high-strength corrugated roofing sheets, structural C/Z purlins, roller shutter doors, and wall cladding panels.
Precision Steel Pipe & Tube Production: Base material for thin-walled structural tubing, conduit pipes, furniture framing, and scaffolding tubes requiring high strength without complex bending.
Hardware & Flat Parts: Flat washers, strapping bands, rigid brackets, and limited blanking/flat components where low elongation is acceptable.
Authentic Steel operates modern coil processing centers featuring high-speed precision slitting machinery. We process raw FH CRC master coils into narrow full hard steel strips with strict width tolerances and minimal edge burrs, tailored to your automated manufacturing equipment. Every batch undergoes rigorous quality testing—including Rockwell hardness verification, thickness gauge checks, and surface oil density testing—ensuring trouble-free processing on your production line.
