A curved sheet, specifically a roof crimped curved sheet, is a roofing material made from steel plate coated with a colored tile material. Typically available in various sizes and with a thickness of 0.60 millimeters (mm), it is designed to provide structural integrity and aesthetic appeal to roofs. The crimped curvature of the sheet enhances its strength and ability to withstand wind and weather conditions. Curved sheets are used primarily in architectural designs requiring curved or arched roofs, such as stadiums, auditoriums, and modern residential buildings. They offer excellent performance in shedding rainwater and snow, while their robust construction ensures durability and long-term reliability in diverse climatic conditions.
