With an annual export value of US$2.5–5 million and overseas offices, we deliver consistent quality and reliable supply to global markets including North America, Europe, Southeast Asia, and Africa.
Product Overview:
Our electrolytic tinplate coil is manufactured using premium low-carbon steel, electroplated with pure tin to provide excellent corrosion resistance, solderability, and an attractive finish. It is specifically designed for high-speed stamping and drawing processes required for crown cork and beverage cap production. Each coil undergoes stringent quality control to ensure uniform thickness, precise dimensions, and consistent coating weight.
Key Features & Technical Specifications:
- High Formability: Suitable for deep drawing and complex cap shapes without cracking or wrinkling.
- Consistent Coating Weight: Tin coating available from 2.8g/m² to 11.2g/m² per side, ensuring optimal protection and solderability.
- Wide Range of Tempers: T1 to T4 options to match specific hardness and ductility requirements.
- Exceptional Surface Quality: Bright, stone, silver, or matte finishes available to suit aesthetic and functional needs.
- Customizable Dimensions: Thickness from 0.18mm to 0.50mm, width from 600mm to 1200mm, and coil inner diameter 508mm or 610mm.
