Tinplate Coil Supplier - Cold Rolled Tin Coated Steel Coil for Packaging & Manufacturing

Tinplate coil supplier operations provide cold rolled steel coils with electrolytic tin coating, serving as critical material sources for food packaging, aerosol containers, and industrial applications requiring superior corrosion resistance combined with formability. These tin-coated steel coils undergo precision electrolytic deposition processes that apply tin layers ranging from 2.8 to 11.2 g/m² per side, delivering exceptional protection against oxidation while maintaining cost-effective production economics for high-volume manufacturing environments across beverage, chemical, and consumer goods sectors.

What is Tinplate Coil Supplier?

A tinplate coil supplier specializes in manufacturing and distributing cold rolled steel coils with electrolytic tin coating applied through continuous electroplating lines. The base material consists of low carbon steel (typically 0.06-0.13% carbon content) processed to thicknesses between 0.15-0.49mm, subsequently coated with pure tin layers meeting ASTM A623 or EN 10202 specifications for packaging-grade tinplate products.

Tinplate Coil Technical Specifications

Standard tinplate coils conform to ASTM A623/A623M-20 and EN 10202:2001 requirements, featuring base steel temper grades from T-1 (soft) to T-6 (extra hard) with Rockwell 30T hardness values ranging 45-65. Coating weights span 2.8/2.8 g/m² for light applications to 11.2/11.2 g/m² for aggressive environments, with surface finishes available in bright, stone, silver, or matte configurations. Coil dimensions typically range 600-1250mm width with inside diameters of 508mm or 610mm, accommodating weights up to 12 metric tons per coil.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Standard MOQ requirements start at 25 metric tons per specification, approximately one full container load. For established customers with ongoing requirements, we accommodate mixed-specification orders meeting 15-ton minimums per grade. Trial orders for new product development accept reduced quantities of 10 tons with adjusted pricing terms.

Do you provide material test certificates?

Yes, every shipment includes EN 10204 Type 3.1 mill test certificates issued by our quality assurance laboratory, documenting chemical composition per ASTM E415 optical emission spectroscopy, mechanical properties per ASTM E8 tensile testing, and coating weight verification per ASTM A623 coulometric analysis. Additional third-party inspection services available through SGS, Bureau Veritas, or TÜV upon request.

What is the typical delivery time?

Standard specifications from existing inventory ship within 15-20 days FOB mill after deposit confirmation. Custom temper grades or non-standard coating weights require 35-45 days production lead time including coil processing, quality inspection, and export documentation preparation. Express production available for urgent requirements with 25-day delivery achievable for premium pricing consideration.

Can you cut to custom sizes?

Our precision slitting capabilities accommodate width tolerances of ±0.5mm for specifications between 100-1250mm. Coil rewind services provide custom inside diameters (406mm, 508mm, 610mm options) with maximum outer diameter control up to 2000mm. Sheet cutting services available through partner facilities for lengths 500-6000mm meeting packaging die-cutting requirements, though minimum quantities apply based on setup economics.
