When sheets are shaped in a corrugated or wavy pattern, it is called corrugated steel. Corten steel can develop a rust like layer called patina on the surface when exposed to weather elements. This natural layer acts as a protective barrier against further corrosion and makes it suitable for outdoor applications.
Corrugated corten steel is used for roofing, siding, cladding and other architectural and landscaping purposes. The corrugated design provides structural strength and adds a visually interesting and rustic element to buildings and structures.
