Useful information
MoreDesigned for extreme environments - the most durable organic coating
Granite® HDXtreme is the latest prepainted steel in our organic coated Granite® range with outstanding durability performances. It has a coating system that provides high levels of protection against UV and corrosion.
It has been designed for use in extreme climates - on roofs and facades of buildings, even those near the sea - but also in other severe indoor environments, such as swimming pools or waste management plants.
The strength of Granite® HDXtreme comes from its 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 contributes to durability and provides the final colour. The coating is finished with a layer of varnish which adds texture to the coating, reinforces durability and surface robustness, and enhances the UV weathering potential of Granite® HDXtreme.
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.
Our 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 plus indoor applications. It can also be used in combination with perforated metal.
