Being highly durable and robust with high tensile strength, corrugated metal sheets are widely used for residential and commercial purposes. From roofing to siding jobs, this sheet should ideally be your number one choice. Coming to their manufacturing process, corrugated sheets are prepared through the cold-form process. What happens during this process? Well, firstly, the sheets are pressed flat and then taken for roll forming to achieve the required shape and pattern. After this, the sheets are cut into the appropriate length. When you see a corrugated sheet, you may notice a wavy pattern. In fact, this is a characteristic feature of the sheet, which helps in its easy identification. That being said, there are also a few other patterns that you may come across.
