Corrugated metal is a material uniquely reminiscent of early twentieth century rural Americana. Even today, if you venture into the countryside, you might catch a glimpse of a chicken coop, barn or outhouse with an old corrugated tin roof. Shortly after corrugated galvanized iron was invented by British architect/engineer Henry Palmer in the 1820s, it quickly became a common building material used in many parts of the developing world. Its utility and durability continues to stand the test of time.
What is corrugated sheet metal? Corrugated sheet metal, often referred to as roofing tin, metal or steel roofing and a variety of other names, is produced by a roll forming process of pulling sheets of galvanized (zinc-coated) metal or aluminum through rolling dies that create rippling patterns in the sheets of metal. Originally made from wrought iron, you can now find corrugated metal sheets in stainless steel, aluminum, copper and a variety of different metals to suit your particular needs.
What are some of the cool properties of corrugated metal? Well, for one, corrugated metal just looks cool. It can appear equally rustic, industrial, or even kitschy.

Bonus fact! The very first corrugated sheets were made made of tin-plated wrought iron, which soon after was replaced by zinc-coated steel. “Tin roofing” remains to this day the most common term used for corrugated sheet metal [via builder bill]. And it’s just as well — because I’m not sure if Cat on a Hot Wrought Iron Roof would have had the same ring.
