Tin Coated Sheet (ASTM B545)

.008" Thickness:
For sheets with a thickness of .008 inches, we proudly offer a solution that speaks volumes about our commitment to excellence: Electrolytic tin coated carbon steel. This specific finish, applied in accordance with the rigorous ASTM B545 standards, is a result of an electrolytic plating process.

Electrolytic tin coating involves immersing the carbon steel sheet in an electrolytic solution containing tin salts. An electrical current is passed through the solution, causing tin ions to deposit onto the surface of the steel sheet. This creates a thin but highly uniform layer of tin that provides several beneficial attributes. This process results in a surface that offers exceptional resistance to corrosion, making it suitable for various environments. It also imparts a polished appearance that enhances the sheet's aesthetic appeal.

The 'Dull Matte' finish, also referred to as a 'Matte' or 'Satin' finish, is achieved through a controlled process that imparts a subdued, non-reflective surface appearance to the tin-coated sheet. Unlike traditional polished or glossy finishes, the Dull Matte finish exudes a gentle, finely textured sheen that minimizes light reflection.

The Dull Matte finish serves a dual purpose. On one hand, it enhances the sheet's aesthetics by giving it a unique and refined appearance that sets it apart from conventional finishes. On the other hand, this finish can also provide certain practical benefits, such as reduced glare and improved fingerprint resistance.
