Most of us are familiar with corrugated cardboard, applied to make cartons, boxes and shipping containers. Corrugated cardboard, created of flimsy paper, is more rigid and stronger than a stack of plain paper. This is as a result of the wavy pattern in which the papers are arranged. Exactly the same principle applies in case of corrugated metal sheet roofing too. Corrugated metal sheet roofing are metal sheets that are created in a wave-like pattern (with ridges and grooves). This pattern offers them added strength, regardless of becoming lightweight. So, these corrugated metal roofing sheets are stronger than plain metal sheets.
Corrugated sheet metal roofing is obtainable in copper, aluminum sheet metal, zinc alloy and stainless steel. All these kinds differ in their features like durability, look and cost. Among them, aluminum is largely preferred for residential purposes, as this metal is affordable and really lightweight. It's also durable and is resistant to rust, even if there's no coating. Nevertheless, this roofing material is typically coated and painted for greater looks and longer lifespan. Stainless steel corrugated sheets come using a 'terne' coating, which provides a natural matte-gray finish towards the roofing. Even so, this sort is incredibly highly-priced. Corrugated metal sheet roofing is also readily available in copper. They're resistant to rust and corrosion, and are uncomplicated to install, but might be really highly-priced. Metal sheet roofing can also be created of alloys, that are really strong and durable, but again, the cost of alloys are on the higher side.
