Coils of stainless steel which have high resistance to corrosion are made from stainless steel alloys which contain a very high quantity of chromium and nickel. This composition offers great resistance to corrosion externally ranging from humid conditions to chemical and even salt water. They are used in outdoor buildings, coastline structures, and industrial chemical plants. Because they resist corrosion, the products made from these coils can maintain their structural integrity over a long period of time, therefore reducing cost of maintenance and replacement in the long run
