Tinplate (SPTE) is a common name for electroplated tin steel, which refers to cold-rolled low-carbon steel sheets or strips coated with commercial pure tin on both sides.

Tin is mainly used to prevent corrosion and rust. It combines the strength and formability of steel, as well as the corrosion resistance, weldability and aesthetics of tin in the material, corrosion resistance, non-toxicity, high strength and good ductility.

iron is not very stable and are easy to oxidize, a strong hardness and easy to formability. People often tin-plated on the outside of iron to prevent corrosion of iron. This type of iron wearing "clothes" is called a "tinplate box."

1 ton of tin can cover more than 7,000 square meters of iron, so tinplate is very common and very cheap. The largest "customer" of the tinplate is the canning industry. If you pay attention to protection, the tinplate can prevent rusted for more than ten years. However, once the tin "clothing" accidentally breaks, the iron piece will soon rust, and soon the entire tinplate is covered with reddish brown rust. Therefore, when using tinplate, should be care taken not to damage the tin layer or to get it damp and heat.

 In life, there is no special way to prevent the tinplate from being corroded. You can brush oil or anti-rust paint on the outside of the tinplate, but you can't damage the skin of the tinplate.
