What Is Tinplated Steel Sheet?
Tinplate(SPTE) is a common name for electroplated tin steel sheets, which refers to cold-rolled low-carbon steel sheets or strips coated with commercial pure tin on both sides. Tin mainly acts to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of tin in a material with corrosion resistance, non-toxicity, high strength and good ductility.
Applications of Tinplated Steel Sheet
Tin-plate packaging has a wide range of coverage in the packaging industry because of its good sealing, preservation, light-proof, ruggedness and unique metal decoration charm. Because of its strong antioxidant, diverse styles and exquisite printing, tinplate packaging container is popular with customers, and widely used in food packaging, pharmaceutical packaging, commodity packaging, instrument packaging, industrial packaging and so on.

Features of Tinplate Sheet
- Excellent Corrosion Resistance
By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents.
- Excellent Paintability & Printability
Printing is beautifully finished using various lacquers and inks.
- Excellent Solderability & Weldability
tinplate is widely used for making various types of cans by soldering or welding.
- Excellent Formability & Strength
By selecting a proper temper grade, appropriate formability is obtained for various applications as well as the required strength after forming.
- Beautiful Appearance
tinplate is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.
Different Features between Tin free steel and Tinplate
| Appearance | Even if original plates with the same surface state are used, the surface appearance of tin free steel is different from that of tinplate, and they exhibit different metallic chrome gloss. |
| Corrosion resistance | The printed tin free steel has excellent corrosion resistance, so it is usually printed on both sides; however, depending on the type of content, the inner and surface of the can Prime iron. |
| Solderability | Tin free steel is not compatible with soldering |
| Weldability | Although tin free steel can be welded when the metallic coating layers are removed, its weldability is inferior to tinplate |
| Coating weights | Tin free steel generally has only one coating thickness, while tinplate has a series of thickness standards. |
Usage Precautions for Tinplate Sheet
- As tinplate is covered by soft metallic tin coatings, due precautions should be taken not to cause scratches.
- Paintability, printability, solderability, and mechanical properties of tinplate tend to deteriorate as time elapses.
- Although tinplae has excellent corrosion resistance, it tends to rust in a humid atmosphere. Use as soon as possible after unpacking.
- Tinplate is dissolved by a strongly alkaline solution. When using tinplate for making cans for alkaline contents, paint the internal surface.
- As contents that contain sulfur cause blackening of the tinplate surface, paint the internal surface.
