Technical details

Organic coated steels are synonym for wide range of colours associated with an endless possibility of surface patterns such as smooth, grained, embossed, textured or orange peel effect. In addition, several finishes can be achieved: from matt to high gloss and even metallic aspect for interior applications.

 In construction, organic coated steels - applied on metallic coated steels - are based on:


  • Saturated Polyester (SP),
  • Polyurethanes (PUR),
  • Polyvinylfluoride (PVDF)
  • Polyvinylchloride (PVC) paints.

In function of the final applications, layer thicknesses for external applications range from 25 to 60µm.

Only PVC coatings go up to 200µm, which allows the possibility to texture the surface with embossment of leather like aspect.

Our ArcelorMittal Europe - Flat products range of outdoor applications is:

  • Granite®, 25 to 55µm thick paint coating systems with excellent durability performances, corrosion resistance of up to RC5* and UV resistance of up to RUV4** 
  • Solano® Nature, 200 µm thick paint coating system with excellent durability performances and a corrosion resistance of up to RC5*

Our ArcelorMittal Europe - Flat Products range of indoor applications includes:

  • Estetic®, up to 25µm thick paint coating system 
  • xcellook®, an electro-galvanised brushed steel with a transparent coating and a natural metallic appearance available in six surface finishes

 * According to the norm EN10169

** According to the norm EN10169-2

Impressive Aesthetics for Buildings

ArcelorMittal Europe - Flat Products, as European leader for Organic Coated Steels (also known as prepainted steels), offers a unique range of products for each application, building type, local environment, performance requirement and aesthetics demand.

Moreover, we are continuously improving the potential environmental impacts of our steel grades. Most of our organic coated products have been certified under ECCA Premium® labelling.

For outdoor applications, our Granite® range offers a solution for each component of a building envelope:

  • Granite® HDX, where outstanding resistance to corrosion and colour stability are required 
  • Granite® Silky Shine and Granite® Silky Mat are synonymic of elegant finishes for facades
  • Granite® Quartz and Granite® Storm for extended durability of your roofing applications combined with exceptional aesthetics
  • Granite® Rain provides a robust system for rainwater applications
  • Granite® Impression with  Granite® Impression Snake & Elephant, Granite® Impression Cloudy, Granite® Impression Wood and  Granite® Impression Agate

For indoor applications, we propose our Estetic® range and xcelloo.

ArcelorMittal is the first steel producer to be granted a new label by the European Coil Coating Association (ECCA). The ECCA Premium® label ensures the quality and sustainability of pre-painted metals for outdoor applications. ECCA developed it to differentiate quality products which meet high European standards from inferior imports.

The benefits of the ECCA Premium® Quality and Sustainability label are numerous for customers, developers and builders in the construction market:

  • Long term aesthetics and durability of colours: a defined and minimum paint system thickness is compulsory to ensure the beauty of the building.
  • Robust and resistant against harsh environment conditions: the thickness of the metallic coating layer is optimized to protect the steel substrate
  • Creative design for complex forms: flexibility and adhesion of the paint are key to allow smooth processing operations
  • Sustainability: the steel used is manufactured in a safe and environmentally responsible way; free of heavy metals or substances of very high concern (REACH). Therefore, ECCA Premium® contributes to green building labels.
