Strict Gauge & Thickness Consistency: Equipped with automated AGC (Automatic Gauge Control) lines, ensuring thickness tolerances are tightly managed within limits superior to standard ASTM A480 requirements. No hidden thin-gauge drops.
Flawless Mechanical Performance: Exceptional elongation and tensile strength make our 304 coils ideal for complex laser cutting, high-deformation bending, and deep-drawn metal stampings.
Clean & Burr-Free Edges: Available in both Mill Edge and Precision Slit Edge options, ensuring zero burrs or waviness to protect your automated feeding machinery.
Tube & Pipe Manufacturing: Base raw materials for high-frequency welded industrial and structural tubing.
Stamping & Kitchenware: Deep-drawing processes for stainless steel sinks, cutlery, cookware, and appliance panels.
Automotive & Transport: Exhaust system components, silencer boxes, and heavy vehicle structural framing.
Industrial Fabrication: Stamped brackets, metal enclosures, laser-cut profiles, and cable trays.
Secure Your Bulk Material Margin – Source Directly from China's Premier Coil Factory
Lock in your raw material costs and eliminate thickness variations. Send us your coil specifications (thickness, width, finish, coil weight, and volume) and get a transparent wholesale quote within 2 hours.

Save processing time and scrap waste with our in-house coil processing services:
Surface Conditions: 2B (Matte Cold Rolled), BA (Bright Annealed), No.4/Hairline (Brushed), 8K Mirror, Anti-Fingerprint.
Precision Slitting & Shearing: High-speed slitting lines to cut master coils into precise-width strip coils (down to 10mm width), and flying shear systems for flat sheet leveling.
Massive Scale Warehouse: 80,000+ Sqm processing facility running multi-platform continuous slitting and leveler machine groups.
Perpetual Master Inventory: Over 25,000 tons of prime master coils (TISCO, BAOSTEEL, CHINGTSHAN) in constant stock, ensuring fast lead times for unexpected bulk demand.
Direct Source Mill Agent: Skip the trading brokers. We offer completely transparent production scheduling and highly competitive wholesale pricing matrices.
Continuous Surface Audits: Automatic optical scanners detect and log any surface scratches, pits, or roll marks across the entire coil length.
PMI Core Chemistry Checks: Hand-held XRF spectrometer verification on every heat number to guarantee exact Nickel (≥8.0%) and Chromium (≥18.0%) composition.
Full Traceability: Every shipped coil is tagged with a unique barcode linked directly to its original MTC (Mill Test Certificate EN 10204 3.1).
Global Footprint: Trusted coil supplier to major steel service centers, distributors, and manufacturing plants in over 60 countries.
Tariff Lowering Documentation: Expertly issuing official Certificates of Origin (Form E, RCEP, Form F, CO) to match your local customs requirements and eliminate or reduce import duties.
Flexible Delivery Logistics: Smooth handling of standard FOB China ports, CIF destination, as well as turn-key DDU and door-to-door DDP shipments.
Horizontal or Vertical Eye Packing: Flexible "Eye to Sky" (Vertical) or "Eye to Wall" (Horizontal) layouts based on your facility's crane/forklift unloading setups.
Multi-Layer Anti-Rust Protection: Encapsulated with desiccant packs, anti-moisture VCI paper, heavy plastic wrap, and solid external steel metal casing.
High-Strength Strapping: Bound securely with 4 to 6 heavy-duty steel bands onto reinforced, fumigated wooden skids to prevent any movement in maritime transit.
Q: Can you slit a 20-ton master coil into specific 3-ton baby coils for our stamping line?
A: Yes, absolutely. Our high-speed slitting and rewinding lines can easily split master coils into precise widths and specific coil weights (e.g., 2 to 5 tons per baby coil) to match your factory's uncoiler capacity.
Q: How do you guarantee the coils will not suffer from sea-water corrosion during long transit times?
A: Every coil is wrapped with VCI (Vapor Corrosion Inhibitor) paper and sealed completely in a waterproof steel structural wrap with desiccant packs. This heavy-duty packaging successfully blocks marine moisture.
Q: What is the typical MOQ for a customized thickness or width cold-rolled coil?
A: For standard 304 stock master sizes, the MOQ is 1 coil. For special customized rolled gauges or non-standard alloys, it typically begins at 3 to 5 tons per specification.
