Cold Rolled Coil is high‑precision coil produced from hot‑rolled pickled coil through multi‑pass cold rolling, continuous annealing and skin‑pass finishing under room temperature. Featuring smooth clean surface and tight dimensional tolerance, Cold Rolled Coil acts as one of the most important raw materials for home appliances, automobile and hardware stamping industries. Cold Rolled Coil mainly includes two mainstream types: Cold Rolled Steel Coil and Deep Drawing Cold Rolled Coil. Ordinary Cold Rolled Steel Coil focuses on general stamping and sheet‑metal forming, suitable for shells, cabinets and common structural parts.Deep Drawing Cold Rolled Coil owns excellent elongation and crack‑resistance performance for complex deep‑drawing formed components.Cold Rolled Coil is rolled under low temperature without hot‑rolling scale defects for clean and uniform surface. Cold Rolled Steel Coil delivers stable mechanical properties with good bending and weldability for mass general processing. Deep Drawing Cold Rolled Coil adopts optimized steel‑making composition and annealing process to lower yield strength and improve elongation rate for multi‑pass complex deep drawing. Cold Rolled Coil has complete specifications and sufficient stock. Deep processing services such as cut‑to‑length, slitting, film lamination, oiling and shearing are available. Custom non‑standard thickness, special width and customized coil weight can be produced. Cold Rolled Steel Coil and Deep Drawing Cold Rolled Coil adapt to various production conditions including home‑appliance manufacturing, auto‑parts, hardware products, cabinet chassis and furniture machinery. Cold Rolled Coil is an indispensable core industrial coil for precision sheet‑metal stamping field.

2. Execution Standards
‑ GB/T 5213‑2019 Cold‑rolled steel sheets and strips, core national standard for Cold Rolled Coil; Q/BQB402 enterprise standard
‑ International Standards: JIS G3141, EN 10130, ASTM A1008, complying with foreign‑trade project acceptance.
Cold Rolled Steel Coil andDeep Drawing Cold Rolled Coil support full‑set tests including mechanical property, metallographic and salt‑spray test.
3. Specification Parameters
Cold Rolled Coil conventional thickness:0.2mm‑3.0mm, conventional width:600mm‑1850mm, coil inner diameter:508mm/610mm, coil weight:3‑25 tons, customized coil weight supported. Cold Rolled Steel Coil thickness tolerance within ±0.03‑0.05mm with flat shape, suitable for mass cut‑to‑length and slitting processing. Deep Drawing Cold Rolled Coil features pure material and high elongation rate, large‑size thin‑gauge Cold Rolled Coil can be supplied stably. All Cold Rolled Coil supports cut‑to‑length sheets, slitting narrow strips and anti‑scratch film lamination, non‑standard sizes can be customized according to drawings.
4. Surface Treatment
‑ Anti‑rust oiled (regular for Cold Rolled Coil): evenly coated anti‑rust oil to avoid rust during storage and transportation, ready for painting and electrophoretic treatment.
‑ Matte dull finish: skin‑pass matte surface for good paint adhesion, widely used for home‑appliance shells of Cold Rolled Steel Coil.
‑ Bright surface: clean bright appearance for decorative and visible parts.
‑ Cold Rolled Steel Coil and Deep Drawing Cold Rolled Coil support protective film lamination to prevent scratch during processing for high‑appearance‑requirement components.
5. Main Applications
Cold Rolled Coil is widely used for home‑appliance shells, automotive stamping parts, power distribution cabinets, hardware goods, furniture machinery, instrument housings and lamp accessories. Cold Rolled Steel Coil is mostly applied for ordinary sheet‑metal, bending and welded components, mass production of cabinet, equipment shells and daily hardware. Deep Drawing Cold Rolled Coil serves for complex deep‑drawing forming parts, automotive interior parts, deep‑drawn home‑appliance shells and complicated hardware stamping parts. Automobile, home‑appliance and hardware manufacturers select Cold Rolled Coil according to stamping difficulty. Cold Rolled Steel Coil is preferred for ordinary sheet‑metal conditions, and Deep Drawing Cold Rolled Coil for complex deep‑drawing conditions, giving full play to advantages of Cold Rolled Coil such as superior surface quality, precise dimension and excellent forming performance.
6. Packing, MOQ & Lead Time
‑ Packing: Cold Rolled Coil adopts seaworthy export‑grade moisture‑proof packing, inner waterproof paper, edge protectors, steel‑strap reinforcement and coil‑end protection to avoid scratch and moisture damage, suitable for land and sea export transportation.
‑ MOQ: 5 tons minimum order, mixed batch of Cold Rolled Steel Coil and Deep Drawing Cold Rolled Coil is available, small‑batch trial order negotiable.
‑ Lead Time: 3‑7 working days for regular stock Cold Rolled Coil; 7‑10 working days for cut‑to‑length, slitting and film‑lamination processing. Mill certificates and mechanical test reports are provided; SGS third‑party inspection is acceptable. Support FOB, CIF, DAP and other international trade terms.
7. Product Advantages
Cold Rolled Coil is rolled under room temperature without mill scale, delivering clean and beautiful surface, high dimensional accuracy and tight thickness & width tolerance to reduce machining allowance.
Cold Rolled Steel Coil has sufficient stock and high cost‑performance, good bending & welding performance, suitable for mass general sheet‑metal stamping production to control procurement cost.
Deep Drawing Cold Rolled Coil provides outstanding deep‑drawing performance with low cracking risk, fit for multi‑pass complex forming and lower rejection rate.
Cold Rolled Coil supports various deep‑processing such as cut‑to‑length, slitting and film lamination, both coil and sheet supply available to match different factory equipment.
Full‑range Cold Rolled Coil has complete qualification documents with stable performance and lab‑test support. Cold Rolled Steel Coil and Deep Drawing Cold Rolled Coil satisfy standards for domestic manufacturing projects and foreign‑trade export.
