Product description
\nRoofinox tin-plated (Terne) is an austenitic stainless steel containing molybdenum with low carbon (316L) with an electroplated coating of tin on both sides. This tin coating is supplied in an unweathered state. The austenitic stainless steel owes its corrosion properties to the alloying elements chrome and molybdenum. The tin coating is in no way connected to the corrosion properties of the stainless steel.
\nBenefits
\n\u2022 When exposed to the weather, the tin coating develops its typical matte grey patina
\n\u2022 Stainless austenitic steel, used for the substrate, is the ideal (long-lasting) roofing material due to its corrosion properties
\n\u2022 The higher alloy makes it more corrosion resistant
\n\u2022 The tin coating makes Roofinox tin-plated easy to solder
\n\u2022 100 % natural and 100 % recyclable
\n\u2022 Easy to work with, even at temperatures below 40\u00b0 F
\nInstructions for use \/ recommendations
\nGeneral Information:
\n\u2022 Roofinox tin-plated should be used in accordance with the latest technical standards, professional regulations and norms.
\n\u2022 No matter whether it is used for cold or warm roofs, Roofinox tin-plated is ideal for the roof itself and all associated flashings on the roof.
\n\u2022 When Roofinox tin-plated is used for standing seam roofs, all seams must be additionally sealed using seam sealant or similar waterproofing methods.
\n\u2022 Roofinox tin-plated is not recommended for vertical surfaces, wall-cladding and soffits because uniform patina and weathering cannot be guaranteed. Direct contact with aggregate concrete slabs, gravel, soil, humus etc. should be avoided. In both cases we recommend using Roofinox Classic or Plus 0.4 mm.
\n\u2022 Transport and storage: Roofinox tin-plated must be transported and stored in a dry, ventilated manner, otherwise the oxidation process will begin (see patination).
\n\u2022 Processing: Roofinox tin-plated is ideal for cold forming (folding, rounding, and roll-forming). For processing, suitable tools should be used (ideally made of stainless steel) and machines should be set for use with stainless steel. It should also be ensured that the sheets are handled with dry hands (dry gloves recommended), so no moisture gets onto the tin coating. Roofinox tin-plated can be processed at low temperatures.
\n\u2022 Soldering: Make sure that only orthophosphoric acid-based flux is used. It is also important to clean immediately with fresh water (or a cleaning agent recommended by the manufacturer) after soldering. The instructions on our information sheet on soldering should be followed.
\n\u2022 Patination: Patination is the process in which the metal reacts with the environmental influences. With Roofinox tin-plated it is
\nthe tin coating that reacts. One of the most important factors is the contact with water and moisture. The result is usually a uniform patina, but this cannot be guaranteed because the building specific environmental influences are not known. Roofinox tin-plated can therefore develop light yellow stains on delivery, which, however, will patinate further with regular water contact. The same counts for gray or black spots which are emerging before delivery or with the first patination. This is part of the point-shaped patination process of Roofinox tin-plated. When patination is complete, Roofinox tin-plated will have adjusted to a more uniform appearance in regards to the overall look, ensuring a homogenous, matte grey finish.
\n\u2022 Cleaning: The surface of Roofinox tin-plated should be cleaned with great care as mechanical cleaning can remove the tin coating, and the bare stainless steel might become visible. This bare, uncoated surface will not repatinate and remain exposed as well as shiny or silverish.
