For a long time, steel has formed the basis for automotive design. It is essential for automobile body panels and frames to have the required stiffness and strength. Its downside is that, when it comes in contact with oxygen, salt, and moisture, steel rusts. Galvanised steel is used by manufacturers to avoid this – steel that has been coated in zinc to provide a protective layer. Steel that has gone through the process of galvanisation is corrosion-resistant, durable and structurally sound in demanding environments.
