The color spectrum ranges from yellow to orange, red, green, brown and black. Within the different color ranges, numerous color gradations are available.

Destillery in Finland made with colored concrete with bayferrox pigments

In the construction of the Finnish Kyrö Distillery Company, the architectural office, Avanto Architects, succeeded in creating a unique design. From the outside, the production and storage hall is barely visible; all you see is a large old woodshed. What looks like decades-old, charred wood is actually deep black reinforced concrete, colored with special pigments from LANXESS.

With our Bayferrox® iron oxide pigments, concrete can be colored all the way through so that no paint is needed. The unusual facade of the distilleries was created with the support of our technicians, because we are also a proven specialist in the coloration of concrete. 

The interesting wood look was created by an elaborate concrete casting process in which old boards from a dismantled barn were removed and served as a template profile for the concrete blocks. The result was, deceptively realistic, the most modern "wooden hut" in the Finnish forests.

Your advantage

We have a complete technology portfolio with sites around the world, covering the entire spectrum of synthetic iron oxide pigments. Our iron and chrome oxides are available in red, yellow, green, brown and black.

Our production processes have always been designed to conserve resources and continuously reduce the environmental impact of our products. All plants are certified according to DIN ISO 9001 / 14001.

Color optimization in the application technology laboratory at LANXESS’s site in Krefeld-Uerdingen. The lattice-like precast concrete element made from ultra-high-performance concrete (UHPC) is colored yellow using Bayferrox pigments. Tests prove that the strength of the meshed concrete structure is unaffected by the pigmentation.
