Indoor coating GRANITE® HDXTREME

matte finishsatinwhite

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. Granite® HDXtreme already exceeds the requirements of the recently published EN 10169-2021 in terms of corrosion and UV resistance. Its exceptional UV resistance offers colour stability for many years.
