Aluminium and Steel


Due to its endless malleability and diverse surface finishes, aluminium gives architects maximum design freedom when planning pioneering buildings suitable for the future – and it is ecologically valuable too. Modern aluminium façade units have low U values. They therefore make a considerable contribution to the positive eco-balance of a building. Optimum material thicknesses when constructing the systems ensure low raw material consumption. Mechanical robustness and corrosion resistance guarantee a long life, and therefore a high degree of sustainability. Aluminium is completely harmless to health. Once extracted it can be recycled indefinitely, retaining all its qualities during the recycling process. Even the swarf can be recycled.


Steel is not expended, it is continually used. Due to it being completely recyclable, steel is a regenerative building material with a closed material cycle. It gives architects and planners maximum flexibility of use due to large spans and is therefore one of the materials with a very good price-performance ratio in the construction industry. Very efficient use of space due to small cross sections increases cost effectiveness. A very long service life with low lifecycle costs emphasises the uniqueness of this material. Steel constructions can be taken apart easily if detachable structural connections are used, offering the alternative of simply converting sustainably planned buildings. An all-round material that adapts to all possible requirements in terms of look and feel, and harmonises with glass and concrete.
