Outstanding standing seam roofs with Granite® HFX Cool Matt and Magnelis®
20 October 2021Across Europe, standing seam roofs are a key feature in the landscape of many cities and towns. Made from flexible metals, they are an ideal solution for the odd-shaped roofs of apartment blocks and public buildings where every millimetre of space under the roof is utilised. The standing seam provides a high level of resistance to wind and excellent watertightness, making it a popular roofing solution today. Organic coated steels such as the Granite® HFX Cool range from ArcelorMittal Europe – Flat Products offer the necessary pliability, combined with a hard-wearing finish that is guaranteed for up to 20 years.

Outstanding standing seam roofs with Granite® HFX Cool Matt and Magnelis®
Across Europe, standing seam roofs are a key feature in the landscape of many cities and towns. Made from flexible metals, they are an ideal solution for the odd-shaped roofs of apartment blocks and public buildings where every millimetre of space under the roof is utilised. The standing seam provides a high level of resistance to wind and excellent watertightness, making it a popular roofing solution today. Organic coated steels such as the Granite® HFX Cool range from ArcelorMittal Europe – Flat Products offer the necessary pliability, combined with a hard-wearing finish that is guaranteed for up to 20 years. Bevego, a leading provider of roofing solutions and equipment for the Swedish market, recently started utilising the latest product in the range – Granite® HFX Cool Matt.
Standing seam roofing
Traditional standing seams are formed from strips of metal which are laid vertically down the roof. The standing seam is formed by bending up the edge of a strip and folding it over, together with the edge of the neighbouring strip. The result is a double standing seam which is totally weatherproof.
Roofing complexity demands ductility
“To achieve the double standing seam, roofers need flexible materials,” says Johan Cronhamn, business area manager for Bevego. “For complicated roofs with lots of dormer windows and chimneys, the work has to be done on site and at height. Granite® HFX Cool Matt handles well and can be formed at temperatures down to -10°C – a key consideration when it comes to the Swedish climate!”
Traditionally, standing seam roofs were made with copper and zinc – metals which are initially bright but become duller over time. In the early 2000s, materials with a gloss finish became more popular. Over the last few years, the market has switched back, explains Johan Cronhamn: “There is a strong preference now for low-gloss roofing. The steel is bent and pressed into shape on the roof and the matt colour disguises any minor marks. That is another reason for the growing popularity of Granite® HFX Cool Matt.”
Magnelis® – the new material for standing seams
Bevego has also been working with a sister company to develop roadside safety equipment out of Magnelis® coated steels from ArcelorMittal. From autumn 2021 they will start to use Magnelis® for standing seam roofs. “Architects like the patina that darkens over time, and Magnelis® has minimal reflectivity, making it suitable for low buildings,” says Johan Cronhamn.
“The Magnelis® we use in roadside applications has a thickness of around 3.0 mm, and it is able to withstand the very corrosive effects of road salts,” notes Johan Cronhamn. “In roofing applications, we will use it in a thickness of 0.6 mm. That will provide the material flexibility roofers need, and long-term protection against corrosion.”
About Bevego

Making roof tiles more beautiful and durable: ArcelorMittal and DACHPOLL strengthen cooperation

Steel roofing is a popular choice in the construction and renovation market. The numerous advantages of steel roofing are what make it so convincing.
The advantages of steel roofing
The roof is one of the most visible, eye-catching elements of a house. If you are looking for an aesthetic, light, and easy-to-install roof with convenient options, all at an affordable price, then you should definitely consider steel roof tiles. It is a solution that has been successfully used for years for roofing in millions of homes and other types of buildings.
A wide range of organic coated steels for roofing applications
ArcelorMittal's range of organic coated Granite® steel for roofing offers a combination of a variety of textures and rich colours. For example: Granite® Storm works impeccably in demanding conditions, Granite® Ultramat offers a distinctive texture and matt finish, and Granite® Impression Cloudy is a steel with unique aesthetics including an appearance resembling natural materials such as clay or terracotta. These coatings are extremely durable and are corrosion and UV resistant.
Challenges in the creation of steel roof tiles
It would seem that there is nothing more pleasant when creating a steel roof tile than inventing its shape - a bend that will enhance the colour or reflect light in a unique way. However, not everyone is aware of the technical and material requirements that should or have to be met. Forming complex shapes on curved, convex, and concave surfaces in addition to the required flexibility of the varnish coat are challenging factors in the creation of steel roof tiles.
A partner in testing ArcelorMittal coatings
To ensure even longer use and greater durability of ArcelorMittal steel roofing, we began working with DACHPOLL to test Granite® Ultramat. Additionally, different tile shapes were tested by analysing bend radii. Thanks to our partner, the shape of the steel roof tiles have been adjusted in such a way so as not to exceed the required parameters for the varnish coat and to offer patterns of roof tiles that meet customers’ expectations.
About DACHPOLL
DACHPOLL have 40 years of experience in profiling roofing sheets and is a manufacturer of sheet metal profiling machines. DACHPOLL have also been conducting research in the field of profiling and sheet metal pressing for many years. A qualified team of engineers and specialists are constantly working to develop even better technological solutions in order to improve the quality of devices and products. As a result, their profiling machines are used by leaders in the roofing industry in Poland and abroad. The dynamic development of the company is also evident via the registration of several hundred industrial designs in patent offices in Poland, the European Union, Russia, and Ukraine. The patented industrial designs of DACHPOLL roofing sheets are currently setting trends in the roofing industry, and ArcelorMittal ensures that our Granite® Ultramat coating is being used at its best.

Individual housing
While designing, building, and buying our new home, we want it to fit all of our needs. It must satisfy all of the requirements concerning functionality, aesthetics, and of course, be energy efficient.
Useful Information
MoreThe ideal home should meet the highest acoustic and fire resistance standards and various technical norms. The construction of a steel frame building is much more time efficient than the traditional technology. Steel frame buildings, which are very popular in North America, fulfil rigorous thermal requirements.
