      \n\t\t\t\t\t\t\t\t\t

      The standard sheet metal casing is treated with anti-corrosive industrial coatings. For prolonged direct exposure to saltwater, we can upgrade the casing material to Marine-Grade Stainless Steel (316L) or anodized aluminum upon request.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
