"corrugated metal"의 정의 및 의미

What is "corrugated metal"?

Corrugated metal is a type of metal sheet that has been shaped into a pattern of ridges and grooves. This design adds strength and stiffness, making the material durable and lightweight. It is often used for roofing, walls, and fencing because it is weather-resistant, affordable, and easy to install. The wavy texture also helps with water drainage, preventing it from collecting on the surface. Corrugated metal is commonly made from steel, aluminum, or tin, and it is often coated to protect against rust and corrosion.
