For very humid areas we have the option of producing extra corrosive resistant canopies and base tanks in a form of stainless steel called 3CR12. Our standard canopies are produced in mild steel that is treated and powder coated. This finish is sufficient for most applications.
3CR12 was developed in the 1970’s by Columbus Stainless. It is now recognised as the world’s most specified 12% chromium utility stainless steel. It is a price competitive, corrosion resistant, weldable, utility chromium steel with particular advantages in wet abrasive applications. 3CR12 meets the European standard 1.4003, included in spec EN 10088. It also conforms to ASTM A240-UNS-S41003.
