Electrolytic Tinplate (ETP)

Tinplate is a light-gauge steel that is electronically coated with pure tin for enhanced corrosion protection. It is available in either a highly reflective bright surface, or as a nonreflective matte finish.

Tinplate is highly formable and weldable, making it suitable for a wide range of canmaking technologies. Because of its corrosion resistance, a wide variety of food products can be packed in tinplate cans. Learn more about electrolytic tinplate from Steelforce Packaging below!

About Our Tin-Plated Steel

Tinplate, also known as electrolytic tinplate (ETP), has a low carbon steel core covered with tin that can be similar or different on each side.

Tinplate consists of five layers that each perform a specific role, including:

  • Steel base – Due to the strength and thickness of the material, the steel base provides stiffness and resists corrosion.
  • Iron-tin alloy – This alloy is made of inter-metallic compound Fe-Sn2 that acts as a barrier due to its electrochemical characteristics.
  • Metallic tin – This serves as a fundamental barrier against corrosion in different food applications, provides a foundation for lithographic printing, and proves effective for applying lacquers.
  • Passivation film – Due to its characteristics, this film makes it possible to improve the electrolytic tinplate to sulphiding, oxidation and rust.
  • Oil film – Using the electrostatic oiler on both ends of the sheet, the oil film protects the tin-plated steel sheet from the environment and facilitates easier handling.

Electrolytic tinplate sheets can be used for stamped parts, lids and ends, oval and cylindrical two-piece cans, rectangular cans, and crown caps for soft drinks.

Some recommendations for product handling include:

  • The material should be stored in a humidity-free environment and never left outdoors to prevent the risk of oxidation.
  • Never handle ETP without gloves and use it immediately after opening.
  • When necessary to wet objects made from tinplate, dry them properly using compressed air or an oven.

What Are Common Applications for Tin-Plated Steel Sheets?

Tinplates are found in various applications and industries because of the unique characteristics they offer. Some common applications for tin-plated steel include:

  • Canned food
  • Canned beverages
  • Automotive parts
  • Aerosols
  • Steel drums
  • High-tension cables

Tinplate is incredibly versatile, allowing it to be applied to many industries and applications. Its corrosion resistance, formability and shiny appearance make it equipped for many uses.
