High-strength CRC cold rolled coil supplied in Full Hard condition (unannealed). Offering consistent gauge control, oil-free or lightly oiled surface, perfect as a substrate for continuous galvanizing and roofing panel roll-forming.
Full Hard CRC Cold Rolled Coil – Ideal Galvanizing Substrate
Authentic Steel manufactures top-tier CRC cold rolled coil in full hard unannealed condition. Produced directly by cold reduction of hot rolled pickling strip without a subsequent annealing furnace cycle, our full hard CRC coils retain high hardness (Rockwell B 85+ or yield strength above 500 MPa). This product serves as the perfect raw substrate for hot-dip galvanizing lines, galvalume coating facilities, and high-strength roll-forming applications.
Key Characteristics of Full Hard CRC
1.High Tensile Strength & Hardness: Excellent resistance against permanent deformation prior to coating, ensuring smooth continuous line feeding.
2.Exact Gauge Consistency: Utilizing automatic gauge control (AGC) system during cold rolling, achieving precise thickness tolerances across the entire coil width.
3.Clean Oil-Controlled Surface: Available dry, lightly oiled, or vanishing oiled, ensuring excellent coating adhesion for galvanizing and color coating.
4.Flexible Coil Dimensions: Thickness range 0.1mm - 2.5mm, width 870mm - 1250mm, inner diameter 508mm / 610mm, coil weight 3 MT to 25 MT.
Primary Applications
Base raw material for hot-dip galvanizing (GI) lines
Base substrate for 55% Galvalume (GL) and Zn-Al-Mg continuous lines
High-strength unannealed corrugated roofing sheets and wall cladding
Heavy-duty steel strapping and reinforced structural strip fabrication
Why Source Full Hard CRC from Authentic Steel? Authentic Steel maintains complete quality control over cold rolling operations in Tianjin. We ensure strict surface cleaning to remove rolling oils and carbon residue, preventing pinholes or flaking during subsequent thermal coating. We support full container loading (FCL) or bulk vessel shipments with custom sea-worthy export packing.
