Corrugated galvanised iron

Hi there! Do you know what a roof is? It's the thing that keeps rain from coming into our house. Sometimes, people use a type of material called corrugated galvanised iron to make the roof.

Now, "corrugated" means that this material is not completely flat. Instead, it has wavy lines on it that make it look like a lot of small hills next to each other. This is important because it helps the roof to be stronger and not break or bend easily.

The word "galvanised" means that the iron has been coated with a special substance that keeps it from rusting. Rust is not good for metal because it makes it weaker and can eventually cause it to break apart.

So, when we use corrugated galvanised iron to build a roof, it means that we have a strong and durable material that will protect our homes from rain and last for a long time without rusting. Pretty cool, right?
