GreenCoat Pural BT with SSAB Zero™ - also called GreenCoat Pural BT / Zero - is available with S280GD Zero. SSAB Zero™ steel is made using recycled steel and fossil-free energy. The SSAB Zero™ EPDs and Certificate of Carbon Emissions is available on ssab.com. The availability of SSAB Zero™ products is subject to limitations and conditions of delivery have to be agreed upon separately. Note: Emissions from the painting process of color coated products are not included in the SSAB Zero™ Certificate of Carbon Emissions. S280GD Zero is manufactured according to EN 10346.
GreenCoat Pural BT / Zero is available in matt, metallic, and satin finishes. It provides a coating where rapeseed oil and other renewable raw materials are used. SSAB has long experience of Bio-based Technology (BT) in GreenCoat® products.
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. GreenCoat Pural BT in metallics, and satin finishes are also premium products for 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 newly developed satin appearance of GreenCoat Pural BT responds well to current architectural and design trends. It has a gloss level of 20.
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.
SSAB Zero™, 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 two years exposure in natural outdoor testing sites as specified in EN 10169.
2) Maximum steel thickness for S280GD Zero is 0.75 mm. Maximum steel width depends on steel thickness. For other steel dimensions or steel grades please contact SSAB Tech Support.
GreenCoat Pural BT color coated steel in satin appearance and Winter White RR20/SS0005 color can be used in addition to outdoor applications, in interior surfaces in food production facilities, where no direct contact is expected between coated surfaces and foodstuff. GreenCoat Pural BT satin in Winter White RR20/SS0005 color is in accordance with EU 1935/2004/EC regulation principles for its intended end use. The product cleanability and wear resistance has been tested according to ISO 11998:2006 and the product has CPI-classification 4.
Below are the colors currently available. Other colors can be agreed upon separately.

Note for Metallic 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.
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.
For easy material identification the reverse side of the sheet is stamped with the GreenCoat logo and the product name. The production date 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.
Temporary protective films are available for protection during processing and installation. Protective films are applied on the top side of the Product. Films will be centered to the strip meaning that typically there are small unprotected areas in both edges of the strip. Unprotected area may be cut away if customer so wishes. Joined film strip ends are marked with red tape on the edge of the Product.
Products with protective film should be stored in dry and warm conditions, since the adhesion between protective film and color coating decreases both in high and low temperatures. Humidity changes also the adhesion properties and in worst case leaves the adhesive part of the film on the Product surface.
Adhesion of protective film increases over time, eventually making it difficult to remove the film from the Product’s surface. Due to that, protective film is recommended to be removed from the material as soon as possible, but no later than six months from the manufacturing of the Product or after one month from the end product installation depending on which comes first.
Protective film decreases friction between coil windings, which creates a high risk of coil collapsing on thin gauge coils. Due to the risk of collapsing, SSAB does not recommend protective films for steel nominal thickness ≤ 0,60 mm. If protective film is essential, following precautions must be taken to minimize the risk of collapsing: Max coil weight < 5 tons and self-supporting coil protection shields must be used in the package.
Typical protective film thickness is around 45µm, max working temperature +80°C and max and min stripping temperatures +40°C & -10°C.
Protective film has a good resistance to forming but is susceptible to cuts. When working with material with a protective film, clean tools that do not damage the film, and appropriate methods are to be used. Cutting fluids are not needed because the film protects the material surface and reduces friction. Cutting fluids may also have negative impact on the protective film and its adhesion.
Films used with GreenCoat Pural BT metallic colors have arrows indicating the painting direction of the strip, which enhances the use of the material in the manufacturing of end products.
Protective films can be recycled as plastics, combusted or disposed via the municipal waste management system depending on the local waste management guidelines and regulations.
