GreenCoat Pural BT
Download data sheet
GreenCoat Pural BT color coated steel is available in regular and matt finishes and offers a wide range of colors inspired by Nordic nature. It uses a patented bio-based coating having Swedish rapeseed oil instead of traditional fossil oil in the paint, which is unique on the market. SSAB holds a worldwide patent for this coating technology (Bio-based Technology, BT).
GreenCoat Pural BT offers the highest level of durability for roofing applications like standing seams, profiled roof tiles and is used widely in metal roofer applications. Besides the regular gloss GreenCoat Pural BT in non-metallic colors can be used in facade products like, sandwich panels and cassettes.
GreenCoat Pural BT color coated steel offers a coating that is optimized to resist weathering resulting in the highest UV (Ruv5 for matt appearance) and corrosion classes (RC5+). The slightly structured surface helps to protect against mechanical wear and is easy to handle during manufacturing. GreenCoat Pural BT possesses excellent forming properties enabling very demanding folding even down to -15°C, allowing for year round installation at lower costs.
The reverse side of the sheet is painted with a two-layer grey backside coating.
GreenCoat Pural BT complies with current REACH regulations and is fully chromate-free.
SSAB’s color coated steels are all manufactured according to EN 10169.
GreenCoat and Pural are trademarks of the SSAB group of companies.

1) Classification into corrosion resistance categories is based on blistering, delamination and damage on bend of the coating after four years exposure in natural outdoor testing sites as specified in EN 10169.
2) Maximum steel thickness is 1.5 mm and maximum steel width depends on steel thickness. For other steel dimensions or steel grades please contact SSAB Tech Support.

Note especially for Metallic and all Matt colors: To ensure tonal consistency of colors on a single exterior face, all material must come from the same production batch. Also the directionality of surfaces has to be consistent especially when sheets are cut to size. Compared to solid colors, larger measured color variation between production batches is typical for metallic colors, even if color is visually stable.
Unless otherwise specified, the reverse side of the sheet is painted with a two-layer coating to further improve the corrosion resistance of the end product. The coating provides good adhesion properties to many adhesives and foams; nevertheless the compatibility needs to be tested case-specifically.
|Nominal Coating Thickness (primer + top coat)||12 µm|
|Corrosion Resistance||Min CPI3|
For easy material identification the reverse side of the sheet is stamped with the GreenCoat logo and the product name. The production year is marked to ease material traceability and can be referred to within the guarantee period. An arrow shows the direction of production to ensure installation in a uniform direction.
