Another popular type of steel roof is one made of standing seam metal. This corrugated product comes in a rolled form. It gets its name from the seams that are created by roofing equipment used to attach each section of steel. When choosing this type of steel roofing or any other type, it’s important to know that the higher the number the lower the grade of steel that you have chosen.
