Metal-based facade materials offer an extremely powerful and wide aesthetical range for use as architectural elements. Their technical properties are equally versatile, which is why our local experts are ready help architects and developers in identifying good solutions to meet individual projects’ aesthetic, technical and economic conditions.

Material and colour are one possible starting point for facade design, but the result depends equally on the products and surfaces used. Our products and services offer quality, predictability and reliability to endless combinations of colours, material, surface shape and even light. The exciting possibilities of Ruukki’s facade cladding products and available materials per product are explained on facade cladding product pages

Our material portfolio for cladding products

Aluminium composite

Colour-coated aluminum composite materials offer excellent surface flatness and enable big product sizes.


Colour-coated metal facade products are a durable way to use colours in all sizes of monotone surfaces and colour compositions.


Patinated Rheinzink has an aesthetically soft, matt surface that gives a very natural impression. The patina changes very little over time.


Brushed design aluminium produces a brushed, directional shine combined with the high gloss of a varnish layer.

Pattern-painted aluminium

The painted pattern on the metal sheet makes the surface livelier when observed at very close proximity. 


Cor-Ten is a solid steel that has a natural, rugged patina that ages continuously in a unique way.

Copper, Brass, Bronze

Patina forming on the wall and various pre-patina options give these solid metals a live, genuine surface for very long time spans.


Glass creates a high gloss and durable flat surface for the facade.

Stainless steel

Stainless steel maintains its shine and appearance very well and, as a solid material, it is very easy to maintain.

Right material for the climate

UV resistance

Coating’s resistance to natural outdoor UV (ultra violet) radiation is described through UV resistance categories Ruv1 – Ruv4 in accordance with EN10169. UV resistance describes how well the coating is able to keep its original colour and gloss levels in outdoor conditions. Coatings in Ruv1 category have very weak UV resistance and should only be used in indoor conditions. Coatings in Ruv4 category have strong UV resistance and are therefore recommended to outdoor use.


Atmospheric gasses and electrolytes react with all façade materials. The rate and effects of those reactions depend on two factors, the atmospheric conditions (e.g. wetness, salinity, sulfur dioxide) and the material in questions. Both vary extensively. For design purposes the atmospheric conditions have been divided into categories (C1-C5) based on their aggressiveness in accordance with EN 12944. Material and coating suppliers can then assess the suitability of their products in each category for normal service life, but the designers will still have to take into account any building specific factors when making the final decisions on façade materials. Note: C class should not be mixed with RC class (EN 10169), which is a classification for coating, not for atmospheric condition.

Corrosivity category Exterior Interior
C1 - Heated buildings with clean atmospheres, e.g. offices, shops, schools, hotels.
C2  Atmospheres with low level of pollution. Mostly rural areas.  Unheated buildings where condensation may occur, e.g. depots, sports halls. 
C3  Urban and industrial atmosphere, moderate sulfur dioxide pollution. Coastal areas with low salinity.  Production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries, dairies. 
C4  Industrial areas with moderate salinity.  Chemical plants, swimming pools, coastal ship- and boatyards. 
C5-I  Industrial areas with high humidity and aggressive atmosphere.  Buildings or areas with almost permanent condensation and with high pollution. 
C5-M  Coastal and offshore areas with high salinity.  Buildings or areas with permanent condensation and with high pollution.
