Tin plating is a process that applies a thin, rust-resistant coating to various metals, commonly steel or wrought iron. The process has evolved over time, allowing for increased production and a wider range of products, including cookware, packaging, and metal components. Tin plating remains a preferred method for certain applications, such as food packaging and metal containers.
Tin plating is a process that is used to apply a thin but uniform coating on different types of metals. Typically, the coating is made from tin and has the added benefit of helping prevent rusting. While tin plating can be used with a number of different metals, the process is most often associated with applying a thin coating to sheets of steel or wrought iron. The use of the process dates back to ancient times and is still in use today, particularly with the production of cans which are used to package food and other types of goods for sale.
Different tin plating strategies have evolved over the centuries, using different types of methods to prepare the surface to receive the coating, as well as the composition of the coating itself. Experimentation with different processes has often made it possible to use the tinplate produced for the production of a wider range of goods. For example, tinning during the 19th and early 20th centuries made it possible to create both cookware and serving pieces that were ideal for everyday use in the home or on camping expeditions. The thin layer of tin provided a durability that minimized the chances of chipping or damage to surfaces, while also making it extremely easy to clean dishes and cookware after use. Best of all, the tinplate was resistant to rust, a benefit that made the cookware ideal for use in humid climates.
Many of the innovations in the tin plating process made it possible to significantly increase production, which in turn made it possible to produce more goods using tinplate in much less time and using fewer resources. This led to even more experimentation in terms of the range of products that could be produced using tinplate. While other methods for sealing and protecting metal surfaces have emerged in the last century, tin plating remains a viable and sometimes preferred method with certain applications, such as preparing cans for use in packaged food production.
The tinning process is still in regular use with a number of different applications. Many of the metal packaging used for products such as paint and other products sold in metal containers undergo this process before use. The end result is a container that is able to keep the contents fresher for a longer period of time, while preventing rust from developing inside or outside the can. In some countries, even the metal used to make bicycles is treated this way, helping components last longer despite exposure to the elements throughout the calendar year. The metal plating used in manufacturing plants and some construction projects can also be treated with a tin plating process as a means of extending the life of the item.
