Galvanising

Galvanizing is a process that objects go through to protect them from rust and corrosion. It's like putting a special suit of armor that keeps them safe from bad things that could hurt them.

First, the object (usually made of iron or steel) is cleaned and dipped in a bath of hot, melted zinc. Zinc is a very tough metal that doesn't rust, so it forms a kind of shield around the object. This bath is a bit like taking a bath yourself, but instead of soap and water, the object gets dipped in hot zinc liquid.

After the object is covered in zinc, it's taken out and left to dry. The zinc hardens on the surface, forming a tough layer that protects it from bad things in the environment that might hurt it, like rain, snow, or dirt.

This process is called galvanizing, and it is used in many different things like nails, bridges, car parts, and even fences. You might not see the zinc layer, but it's there, keeping things strong and safe for a long time.
