Prime tinplate steel coil represents a specialized cold-rolled steel product featuring an electrolytic tin coating, engineered specifically for food packaging, beverage cans, and industrial container applications. This premium-grade material combines the structural integrity of low-carbon steel with tin's exceptional corrosion resistance, delivering superior formability and solderability for manufacturers requiring reliable, food-safe metal substrates. Targeted at packaging producers, can manufacturers, and industrial fabricators, prime tinplate steel coil serves as the preferred choice for applications demanding both mechanical strength and non-toxic surface properties.
What is Prime Tinplate Steel Coil?
Prime tinplate steel coil is cold-rolled low-carbon steel substrate electroplated with a thin layer of pure tin, typically ranging from 2.8 to 11.2 grams per square meter per side. The base steel, manufactured to ASTM A623 or EN 10202 specifications, undergoes continuous electrolytic tinning to create a dual-layer metallic coating that provides outstanding barrier properties against moisture, oxygen, and light contamination.
Prime Tinplate Steel Coil Technical Specifications
The substrate consists of cold-rolled steel with carbon content limited to 0.13% maximum and manganese between 0.30-0.60%, ensuring optimal ductility for deep drawing operations. Standard coating weights range from T-1 (2.8g/m²) to T-5 (11.2g/m²) per side, with temper grades from T-1 (extra hard) to T-6 (dead soft) available per customer forming requirements. Typical coil dimensions span 600-1250mm width with thickness options of 0.15-0.49mm, supplied in coil weights up to 12 metric tons.
Why Choose Our Prime Tinplate Steel Coil
Our manufacturing facility operates continuous electrolytic tinning lines equipped with automated thickness control systems, ensuring coating uniformity within ±5% tolerance across the entire coil width. We maintain ISO 9001:2015 and FSSC 22000 certifications, with mill test certificates documenting tin coating weight, surface finish Ra values, and wettability test results per ASTM A599 Section 7. Our technical team provides application-specific temper recommendations and can supply differential coating (asymmetric tin layers) for specialized forming operations requiring varied surface characteristics.

Frequently Asked Questions
What is the minimum order quantity (MOQ)?
Our standard MOQ is 25 metric tons per specification, allowing for mixed temper grades within the same base coating weight. For trial orders or specialized applications, we accommodate reduced quantities of 10 tons with adjusted lead times, enabling customers to validate material performance before committing to full production volumes.
Do you provide material test certificates?
Yes, every coil shipment includes EN 10204 3.1 mill test certificates documenting chemical composition per heat, mechanical properties (yield strength, elongation, hardness), tin coating weight via coulometric analysis, and surface wettability results. Additional testing for lacquer adhesion, porosity, or specific food contact compliance can be arranged upon request.

What is the typical delivery time?
Standard prime tinplate steel coil orders require 35-45 days from purchase order confirmation, including production scheduling, electrolytic tinning, passivation treatment, and quality inspection. Expedited processing is available for urgent requirements, potentially reducing lead time to 25-30 days depending on current production capacity and coating weight specifications.

Can you cut to custom sizes?
Our slitting capabilities accommodate custom widths from 100mm to 1250mm with tolerance of ±0.5mm, and we offer precision shearing services for sheet cutting to specific dimensions. For high-volume requirements, we provide slit coil packaging with protective interleaving and edge protection, optimized for automated can body manufacturing lines or stamping press operations.
