GreenCoat PURMATT (SSAB)
GENERAL INFORMATION
GreenCoat® Pural BT coated steel offers a wide range of shades inspired by
Nordic nature. The coating uses Swedish rapeseed oil and other renewable raw
materials. SSAB has extensive experience in using biotechnology (BT) in GreenCoat®
products.
GreenCoat Pural BT provides the highest durability for roofing applications,
such as standing seam and profiled metal tiles, making it widely used in roofing
metalwork. GreenCoat Pural BT with metallic, satin, or standard finishes is also
used for manufacturing high-quality facade products, such as sandwich panels
and cassettes.
The GreenCoat® Pural BT steel coating is optimized to withstand weather
exposure, ensuring the highest UV resistance (Ruv5 for the matte version) and
corrosion resistance (RC5+ class). The product has excellent scratch resistance
and is easy to process during manufacturing. GreenCoat® Pural BT has outstanding
forming properties, allowing complex bending work at temperatures down to -15°C,
enabling year-round work at lower costs.
GreenCoat® Pural BT complies with the REACH regulation and contains no chromates.

Technical warranty | 50 years |
Aesthetic warranty | 25 years |
MATERIAL ADVANTAGES AND PROPERTIES
Bio-based Technology (BT) — the GreenCoat® coating thickness is 50 µm.
The reverse side of the sheet has a two-layer coating to provide corrosion
resistance for the final product. The coating also ensures good adhesion
properties for adhesives and foams; however, compatibility should be tested
in each case separately. The nominal thickness of the reverse side coating is 12 µm.

Polyester Matte (PE Mat)
GENERAL INFORMATION
Among metal roofing products, metal with a polymer coating has gained the greatest popularity.
For its production, steel sheets are used, which are coated on both sides with a protective metal
layer, a primer layer, and a decorative polymer coating. The final layer gives the product color
and texture, as well as protects it from external factors.
Perforation warranty | 30 years |
Delamination warranty | 10 years |
