Terne Coated Stainless Steel (TCS) was manufactured by Follansbee Steel from about 1968 to 1997. It consists of Type 304 stainless steel sheet with an eighty percent lead/twenty percent tin-alloy coating on both sides. The thickness of the coating was approximately twenty-five microns. TCS had many advantages over traditional terne metal (lead/tin alloy on steel sheet) for roofing and cladding.
In this WJE Primer article, Jeffrey Levine discusses how changing atmospheric pollutants can discolor lead-tin-alloy-coated stainless steel roofing.
