Galvanizing vs. Tinning — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on October 5, 2023
Galvanizing involves coating steel or iron with zinc to prevent rusting, while Tinning means coating objects with a layer of tin, often for soldering or food safety.

Key Differences
Galvanizing is a process mainly concerned with adding a protective zinc layer to steel or iron to prevent corrosion and enhance its durability. Tinning, on the other hand, involves the application of a tin layer to various metals.
Both Galvanizing and Tinning are forms of metal protection, but their application and purpose differ. For instance, galvanized metals are widely used in construction due to their resistance to rust, while tinned metals are common in the food industry and electronics due to the non-toxic nature of tin and its ability to conduct electricity.
Galvanizing, in general, offers a more robust resistance to environmental factors, particularly moisture, which causes rust in iron and steel. Tinning provides metals with a smoother finish, suitable for soldering and reducing the risk of contaminating food.
Both processes have been employed for centuries, showcasing humanity's ongoing effort to prolong the lifespan of metal products and enhance their utility.

Tinning
Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. The term is also widely used for the different process of coating a metal with solder before soldering.It is most often used to prevent rust, but is also commonly applied to the ends of stranded wire used as electrical conductors to prevent oxidation (which increases electrical resistance), and to keep them from fraying or unraveling when used in various wire connectors like twist-ons, binding posts, or terminal blocks, where stray strands can cause a short circuit.
Galvanizing
To stimulate or shock with an electric current.
Tinning
Symbol Sn A crystalline, silvery metallic element obtained chiefly from cassiterite, and having two notable allotropic forms. Malleable white tin is the useful allotrope, but at temperatures below 13.2°C it slowly converts to the brittle gray allotrope. Tin is used to coat other metals to prevent corrosion and is a part of numerous alloys, such as soft solder, pewter, type metal, and bronze. Atomic number 50; atomic weight 118.71; melting point 231.93°C; boiling point 2,602°C; specific gravity (gray) 5.77, (white) 7.29; valence 2, 4. See Periodic Table.
