The Granite® HDX colour coating is organic and is applied immediately after galvanisation. This guarantees perfect adhesion of the coating and a very uniform layer thickness of 55 μm, This ensures long-term protection in aggressive environments. Available in the aesthetic colours RAL 6009 and RAL 7038.
Enduring and robust pre-painted steel for harsh weather conditions or aggressive environments with RC5 (corrosion resistance category) certification, the best-in-class corrosion resistance category according to EN 10169.
Colours remain stable and attractive, even in the coldest northern climates or the most sun-drenched southern countries with RUV4 (UV resistance category) certification, the best-in- class UV resistance according to EN 10169.
Classified RC5 – the best-in-class corrosion resistance category under EN 10169 – Granite® HDX ensures a durable construction.
The product has been fully tested by experts under extreme corrosion and weathering conditions. Tests have been conducted both in the laboratory, and at outdoor exposure sites across the world.
Granite® HDX is rated RUV4 – the highest UV resistance category according to EN 10169. That means the Granite® HDX paint system will maintain its colour and gloss over time, even in the most extreme climates.
High-performance paint system which allows shape-freedom thanks to the excellent flexibility of the polyurethane paint. Scratch resistance is assured by the grained surface of Granite® HDX.
Granite® HDX can be processed by cold roll-forming, bending, or deep drawing without damaging the top surface.
