Making Granite® roof tiles more beautiful and durable

The roof is one of the most visible, eye-catching elements of a house. Around the world, steel roofing solutions are a popular choice due to their light weight, aesthetic possibilities, and ease of installation. And above all, steel roofs are very affordable.

A wide variety of textures and colours

ArcelorMittal's Granite® range of organic coated steels for roofing offers a wide variety of textures and rich colours. One of the most striking products in the range is Granite® Ultramat. The distinctive texture and matt finish of Granite® Ultramat is extremely durable and highly resistant to corrosion and UV light.

Cooperation with DACHPOLL proves durability

To ensure the durability of Granite® Ultramat, ArcelorMittal worked with DACHPOLL, a leading Polish manufacturer of profiling equipment for roofing, to test the coating in production conditions. DACHPOLL utilised their state-of-the-art equipment to bend and form the Granite® Ultramat into tile shapes. The result of this cooperation has proved the durability of the Granite® Ultramat coating in real-life conditions.
