ArcelorMittal launches new steel product for extreme climates

ArcelorMittal Europe – Flat Products has created a new product designed for use in extreme climates. Granite® HDXtreme is the latest pre-painted steel in ArcelorMittal’s organic coated Granite® range. It has a coating system that provides high levels of protection against UV and corrosion.

The steel is designed for roofs and façades on buildings near the sea, and its performance is guaranteed for up to 40 years. Chromates and heavy metals-free, and 100% recyclable, Granite® HDXtreme is highly sustainable: it has a lower CO2 footprint compared with alternative solutions such as aluminium. Customers ordering Granite® HDXtreme can also purchase XCarb™ green steel certificates alongside their order of physical steel, allowing customers to report an equivalent reduction in their Scope 3 emissions.

The strength of Granite® HDXtreme comes from its 75µm three-layer coating system. Each layer performs a different but integral function. The primer layer plays a key role in corrosion protection. On top of that is a basecoat, which ensures the steel’s durability and provides the final colour. The coating is finished with a layer of varnish which adds texture to the coating, increases durability and surface robustness, and enhances the UV weathering potential of Granite® HDXtreme.


ArcelorMittal’s Indi building in Gent (Belgium) is the first to feature Granite® HDXtreme.

Weathering resistance

Granite® HDXtreme already exceeds the requirements of the latest European standards. Its exceptional UV resistance offers colour stability for many years(1).

Automatic guarantees

ArcelorMittal’s extensive experience and testing, including in highly corrosive seafront locations, translates into a long-term guarantee of up to 40 years for Granite® HDXtreme. The guarantee is applicable to roofs and facades as well as the installation of rooftop photovoltaic modules.

Three finishes, almost 50 colours

Created in consultation with architects and designers, Granite® HDXtreme is available in a huge palette of colours and three different finishes: satin, matt and sparkling.

Samples of Granite® HDXtreme are available through our online sample shop.

(1) Updated EN 10169 standard for continuously organic coated flat steels. Granite® HDXtreme is also ready to pass the upcoming new RUV5 UV resistance standard when published later in 2021.
