| Surface Finish | ||
|---|---|---|
| Classification | Symbol | Specific Feature |
| Bright Finish | B | A luster finish provided by a flow-melted tin coating on a smoothly finished steel based with grindstone-pattern. |
| Stone Finish | R | A luster finish provided by a flow-melted tin coating on a steel base characterized by a directional grindstone-pattern. |
| Silver Finish | S | A luster finish provided by a flow-melted tin coating on a coarse dull-finished steel base. |
| Matte Finish | M | A dull finish usually provided by an unflow-melted tin coating on a dull finished steel base. |
The electrolytic tin layer forms a uniform protective barrier, effectively isolating the steel from external factors such as humidity, oxygen, and chemical exposure. This ensures long-term durability in both food and industrial environments.
The material supports stable welding and seaming processes, which are essential for:
- 3-piece can bodies
- Sealed industrial containers
Reliable weld performance improves production consistency and reduces defect rates.
The controlled surface condition enables excellent coating and printing performance:
- Strong lacquer adhesion
- Uniform ink distribution
- Consistent surface appearance
This is critical for packaging applications requiring both protection and visual quality.
- Tight tolerance on tin coating weight
- Uniform distribution across strip width
- Improved batch consistency
- Reduced variation in large-scale production
- Soft drinks (Coca-Cola, soda)
- Beer cans
- Energy drinks
- Juice packaging
- Liquid food cans
- Aerosol cans
- Specialty metal containers
