Technical Specifications of Tin Coated Steel Coil

Tin Coated Steel Coil - Cold Rolled, ASTM A653 Standard, 0.15-2.0mm Thickness

Tin coated steel coil represents a specialized cold-rolled steel product featuring a thin metallic tin layer electroplated onto high-quality low-carbon steel substrate. This engineered material combines the structural integrity of steel with tin's exceptional corrosion resistance and solderability, making it the preferred choice for food packaging, electronics manufacturing, and chemical processing industries. Manufactured according to ASTM A653 specifications, our tin coated steel coil delivers consistent gauge precision from 0.15mm to 2.0mm thickness, ensuring optimal performance across demanding applications requiring both mechanical strength and surface protection.

What is Tin Coated Steel Coil?

Tin coated steel coil is a cold-rolled steel substrate with an electrolytic tin coating applied through continuous electroplating processes. The base material typically consists of low-carbon steel with carbon content limited to 0.08% maximum, providing excellent formability while the tin layer (ranging from 2.8 to 11.2 g/m² per side) delivers superior resistance to atmospheric corrosion and maintains non-toxic surface properties essential for food contact applications.

Tin Coated Steel Coil Technical Specifications

Our tin coated steel coil complies with ASTM A653/A653M standards, featuring thickness tolerance of ±0.02mm for gauges below 0.5mm and ±0.03mm for heavier sections. The tin coating weight meets ASTM A623 requirements with designations ranging from #25 (2.8 g/m²) to #100 (11.2 g/m²), while the steel substrate exhibits tensile strength of 290-410 MPa and elongation values exceeding 32% per ASTM A370 testing protocols. Surface finish options include bright, stone, and matte finishes with Ra values between 0.2-0.8 μm.

Why Choose Our Tin Coated Steel Coil

We operate ISO 9001:2015 certified production facilities utilizing advanced electrolytic tinning lines with precise current density control ensuring uniform coating distribution. Our mill-direct pricing structure eliminates intermediary costs while maintaining premium grade quality verified through continuous inline coating weight measurement and surface inspection systems. Each coil shipment includes material test certificates documenting chemical composition per ASTM E1019 and coating weight verification per ASTM A623 Section 8.3, providing full traceability for quality-critical applications.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 10 metric tons per specification, though we accommodate smaller trial orders of 5 tons for new customers. Mixed container loading is available for orders combining multiple thickness or coating weight specifications, subject to 25-ton total minimum.

Do you provide material test certificates?

Yes, we supply EN 10204 Type 3.1 mill test certificates with every shipment, documenting chemical analysis results, mechanical properties testing per ASTM A370, and coating weight verification. Additional third-party inspection certificates from SGS or Bureau Veritas can be arranged upon request.

What is the typical delivery time?

Standard lead time ranges from 25-35 days for stock specifications after deposit confirmation. Custom thickness or coating weight requirements may extend to 40-45 days depending on production scheduling. Express processing is available for urgent orders with 15-20 day delivery at premium rates.

Can you cut to custom sizes?

We provide precision slitting services with width tolerance of ±1.0mm for widths from 20mm to 1,250mm, and length cutting with ±2.0mm accuracy. Blanking to specific rectangular dimensions is available through our in-house shearing lines, maintaining edge quality suitable for direct stamping operations without secondary processing.
