Terne stainless steel roofing. Terne coated stainless steel roof panels terne coating is a a zinc tin alloy metal coating process that gives extra corrosion resistance. The company was founded in the early 1800 s and had changed hands a number of times since then. Terne metal roofing or terne ii coated metal roofing are used where copper roof runoff or corrosion are special concerns. Tcsii or tcs2 terne coated stainless steel sheet metal is manufactured with type 304 stainless steel coated in both sides with terne alloy 50 tin 50 zinc.

Terne coated stainless steel a terne coated stainless standing seam cladding comprises of terne coated stainless coils fixed to one another via two vertically standing seams. Terne coatings can be applied to carbon and stainless steels. When compared to regular stainless steel roofinox 20 softer 4 times more matte much easier to solder and due to the low thermal expansion and the high strength of the material it offers a high level. Roofinox tin matte terne coated stainless steel is commonly manufactured with type 439 stainless steel coated in both sides with 100 tin unlike the no longer manufactured tcsii.

Why select terne for your project. Terne is a mild steel with a coating of zinc and tin alloy to protect the steel from rust. It offers a soft looking protective patina that develops after exposure to the elements. The seams are then crimped together on site to seal the system and prevent water penetration.

The new material is also coated with zt alloy which reduces the potential for oxidation before painting on the job with rapidri paints. In 2012 follansbee steel history video stopped producing what we have come to know as terne metal or tin roofing. Terne ii is an improved version of historic terne metal with better capability for resisting corrosion in all environments as well as excellent formability solderability and affinity for paint. Terne coated stainless steel roofing is offen used by architects for its ability to mimic the colour of aged lead sheeting and it is also commonly specified by planning departments on heritage buildings and churches to either replace lead or to blend in with surrounding buildings.

Other terne coatings using lead can present an environmental contamination worry from lead leachate found in roof runoff. The patina creates an elegant tin grey surface exposure to the weather leads to the patination process ideal for all roof types including drainage solutions and accessory pieces. Their version of terne is a thick layer of 100 tin covering a 441 grade stainless steel base. Highly corrosion resistant which makes it an ideal roofing material.
