What process is applied to corrugated iron to make it strong and durable?

Answer 1

The process applied to corrugated iron to make it strong and durable is known as galvanization. Galvanization is a process of coating the iron or steel with a layer of zinc, which helps protect the underlying metal from corrosion and increases its strength and durability.

In the galvanization process, the corrugated iron sheets are first cleaned to remove any impurities such as dirt, oil, or rust. Then, the cleaned iron sheets are dipped into a bath of molten zinc, or they are sprayed with zinc coating. The zinc coating bonds with the iron surface, creating a protective layer that acts as a barrier against moisture, atmospheric corrosion, and other elements that can harm the metal.

The zinc coating provides sacrificial protection to the iron, meaning that if the iron gets scratched or exposed, the zinc layer will sacrificially corrode instead of the iron. This significantly extends the lifespan of the corrugated iron, making it more resistant to rust and corrosion, as well as improving its overall strength and durability.
