ApplicationsCladding for façade systems
CharacteristicsVariety of shapes, colors and materials; versatile technical properties
Ruukki products come in various combinations of shapes, colors, and materials. They offer a powerful and wide aesthetical range for use as architectural elements. Their technical properties of the product and material combinations are equally versatile. Ruukki's local experts are on hand to help architects and developers in identifying good solutions to meet individual projects’ aesthetic, technical and economic conditions.
- Color-coated steel and aluminum:
Color-coated metal façade products are a durable way to use colors in all sizes of monotone surfaces and color compositions.
A titanium alloyed zinc and the sheet is homogenous metal. Patinated Rheinzink has an aesthetically soft, matte surface that gives a very natural impression. The patina changes very little over time.
- Copper, brass, and bronze:
Copper can be pre-patinated to a variety of colors. Greenish pre-patinated colors change less than others over the years. The color of naturally formed patina for copper, brass, and bronze depends on environmental conditions, typically resulting in a dark brownish matt surface. Each alloy will attain a different hue. Nordic Royal is alloyed with aluminum and retains its color.
Brushed design aluminum produces a brushed, directional shine combined with the high gloss of varnish layers. It is a natural brushed aluminum with a transparent or slightly tinted varnish layer.
- Pattern-painted aluminum
Aluminum can be pattern-painted in a coil-to-coil process in factory conditions using a series of rollers and paints. The gloss level varies depending on pattern type.
An almost pure steel that, in the right conditions, forms a natural, rugged, protective patina. Using Cor-Ten as a face material requires specific structural and chemical know-how. When used correctly Cor-Ten is expressive, long-lasting and maintenance-free material. All of Ruukki’s available Cor-ten products are designed and tested to perform reliably. They age continuously in a beautiful, safe and controlled way.
Creates a high gloss and durable flat surface for the facade. Vibrant colors in different glazing sizes together with narrow and freely located joints enable multiple combinations.
- Stainless steel
These are solid materials available in a variety of surface finishes that give them different levels of reflectivity and different textures. Stainless steels can be colored by vaporizing a titanium alloy on the surface. Stainless steel is available in grades to meet on-site climate conditions, typically AISI 304 and AISI 316L.

Technical Properties Explained:
- UV Resistance
Coating’s resistance to natural outdoor UV (ultraviolet) 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 color 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 question. 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, 1 being the mildest environment and C5 being the most aggressive environment.
