EN-Construction-Product-Colorcoat Prisma | Product performance

Product performance


Colorcoat Prisma® uses the unique and proven Galvalloy® metallic coating by Tata Steel. Galvalloy® is made with a special mix of 95% Zinc (Zn) and 5% Aluminium (Al) that conforms to EN 10346:2015. The carefully developed proportions of Zinc and Aluminium in Galvalloy® offers a combination of increased barrier and sacrificial protection when compared with conventional Hot Dip Galv (HDG) coatings and provides unrivalled corrosion protection, even at the cut edges.


Reaction to fire

Colorcoat Prisma® is classified as A1 in accordance with EN 13501-1:2007 and A1:2009.

Resistance to fire

For products covered by EN 14782:2005 Colorcoat Prisma® is deemed to satisfy, without the need for further testing, the requirements for external fire performance of roof covering product in accordance with Commission Decision 2000/553/EC.

UV Resistance

All colours surpass requirements of Ruv4 as per EN 10169:2015 proving outstanding colour retention.

Corrosion resistance

All colours surpass requirements of RC5 as per EN 10169:2015 proving outstanding corrosion resistance for external building cladding systems.

Natural weathering

Natural weathering testing is an essential part of testing the corrosion resistance of a pre-finished steel product. Colorcoat Prisma® has undergone a comprehensive programme of testing in key weathering climates around the world.

Exposure sites were chosen in order to provide the full spectrum of weathering zones from equatorial and tropical climates to urban, rural, industrial and coastal locations.

British Board of Agrément Certificate
The long-term performance of Colorcoat Prisma® has been recognised within the BBA certificate 91/2717 and relates to the product use as external roofing and cladding or internal lining. “Colorcoat Prisma® coating and metal treatment will protect the steel substrate against corrosion for a period in excess of 40 years in normal industrial, urban and rural environments”.

Testing according to Russian GOST standards
Colorcoat Prisma® has been tested by MISIS in Russia which concluded that when used in difficult climatic conditions (e.g. coastal areas) of medium aggressive environments, it should have its functional and aesthetic properties unchanged in Southern and Northern Russian regions with temperatures ranging from +60 to -60 degrees C.

U-mark certification
Colorcoat Prisma® is being tested by the Karlsruher Institut für Technologie according to DIN 55928-8 and DIN 55634.

Colorcoat Prisma® has also been tested according to a variety of key ASTM test standards for corrosion and UV resistance. For markets that require ASTM test results please contact us.

Colour consistency
If tonal consistency is critical, all cladding for a single elevation should come from the same production batch. All metallic shades exhibit a degree of directionality.  

Matching components
If accessories made from other materials are to be colour-matched to the roof or wall cladding, the best reference is the actual profiles or panels delivered to site, or material from the same batch.

Metal hand samples
Metal hand samples are available for all colours. For a truer representation of colour and effect, please obtain metal hand samples.

Our commitment to sustainability also means we actively manage our impacts and contribution throughout the full life of our products - with our suppliers, within our own operations, through the supply chains we serve and by taking responsibility for recycling steel. Colorcoat Prisma® has achieved BES 6001 responsible sourcing certificate which reinforces our commitment to sustainability.

Life Cycle Assessment
We constantly strive to ensure that the manufacturing processes and materials used to manufacture Colorcoat Prisma® are the most sustainable available. Moreover, the enhanced robustness and durability of Colorcoat Prisma® mean that it significantly outperforms other pre-finished steel in terms of environmental impacts over the full life cycle. To demonstrate the environmental impacts, Tata Steel have published an Environmental Product Declaration (EPD) for each of the Colorcoat® assessed cladding systems, based on an initial Life Cycle Analysis.

System environmental assessment
In the UK all roof and wall systems using pre-finished steel achieve a Green Guide A+ rating. Manufacture and processing of Colorcoat Prisma® into building envelope products, through our approved supply chain, can meet the responsible sourcing criteria for BREEAM. Our manufacturing site has an environmental management system which has been certified to ISO 14001.

Colorcoat Prisma® is truly recyclable without any loss of quality, time after time. There is a well established and very efficient steel recycling infrastructure which ensures that all steel collected at end of life goes back into steel manufacture. Through this efficient recycling of steel, the environmental investment in steel-making is never wasted, making steel the most sustainable construction material.
