Technical details
Organic coated steels are synonymous with a 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 finishes.
In construction, organic coated steels that are applied on metallic substrates Z or ZM are mostly based on:
• Saturated Polyester (SP)
• Polyurethanes (PUR)
• Polyvinyl Fluoride (PVDF)
Layer thicknesses for external applications range from 25 to 75µm.
Our range of organic coated steels for outdoor applications includes:
• Granite® 25 to 75µm thick paint coating systems with excellent durability performance, corrosion resistance of up to RC5+*, and UV resistance of up to RUV5*
Our range for indoor applications includes:
• Estetic® up to 25µm thick paint coating systems
* According to the EN 10169-2021 standard

Impressive aesthetics for buildings
As the European leader for organic coated steels (also known as prepainted steels), ArcelorMittal Europe - Flat Products offers a unique range of products for each application, building, environment, performance requirement, and aesthetic demand.
Moreover, we are continuously reducing the environmental impact of our steels.
For outdoor applications, our Granite® range offers a solution for each component of a building envelope:
• Granite® HDXtreme: the latest prepainted steel in the organic coated range and the most durable organic coating for construction
• Granite® HDX: where outstanding resistance to corrosion and colour stability are required
• Granite® Silky Shine: synonymous with elegant finishes for facades
• Granite® Quartz and Granite® Storm: for extended durability of your roofing applications combined with exceptional aesthetics
• Granite® Impression: with Granite® Impression Cloudy, Wood, Agate, and Patina
• Granite® HFX Cool: for standing seam roofs and facades
• Granite® Ultramat: specifically for roofing tiles – with a high quality and flexible paint system
For indoor applications, we recommend our Estetic® range:
• Estetic® BioAir Mat: made of a 100% biobased resin which improves indoor air quality
• Estetic® Clean: meets the most stringent requirements for cold rooms
• Estetic® Mat: with a light matt finish with excellent resistance to marking
• Estetic® Tex: with a grained anti-scratch finish for robust usage
The benefits of ArcelorMittal organic coated steels are numerous for construction stakeholders:
• Long-term aesthetics and durability of colours: a defined minimum paint thickness is compulsory to ensure the beauty and durability of a building.
• Robust and resistant against harsh environment conditions: the thickness of the metallic coating layer is optimised to protect the steel substrate.
• Creative design for complex forms: flexibility and adhesion of the paint are key to allow for smooth processing operations.
• Sustainability: the steel used is manufactured in a safe and environmentally responsible way and free of heavy metals or substances of very high concern (REACH).
