Corrugated iron was developed and patented in Britain around 1830 and has travelled the world.

The gold rushes of the nineteenth century were a spur to the migration of thousands of people to the far corners of the globe, where there was little infrastructure. Victorian Britain was the workshop of world and saw export opportunities for corrugated iron on the goldfields of California, Australia and South Africa. The nature of corrugated iron, being light, easy to stack, and portable, made it an ideal building material to export to places such as Kalgoorlie or Pilgrim’s Rest, which were at the back of beyond.
What is corrugated iron?

Originally made from wrought iron, but since the 1890’s made from mild steel, it is often supplied with a hot-dip galvanised finish to prevent rusting. Its merit over traditional building materials, i.e. masonry or timber, is that it is cheap, durable, lightweight, strong, re-usable and easily transported; such versatility is the key to its...
