German companies supply stainless steel for Burj Tower façade in Dubai
The Burj Tower in Dubai was officially opened in January of this year and since then has been accessible to the public. At 818 m high, the tower is the tallest building in the world. Stainless steel made in Germany has been used to clad the skyscraper’s façade. The ThyssenKrupp Nirosta company produced the material in Krefeld and rolled it in its plant in Dillenburg.
The company’s German partner, Strukturmetall in Bretzfeld-Schwabbach near Heilbronn, processed the material and delivered 400 tonnes to Dubai, where it was sliced. These strips, 420 mm wide, are wall-mounted on the edges of the floors and frame the huge glass windows in the façade. The gigantic tower has been under construction since 2004. Some 850 piles, driven up to 55 m deep into the desert, now carry the load of 230 000 m³ of concrete and 31 000 tonnes of steel. In selecting the material to frame the windows, the engineers and designers were guided not only by stainless steel’s architectural beauty and resistance to environmental influences. They also took care to ensure that the material would not reflect the sun too strongly and distract pilots approaching Dubai Airport.
The requirements specified by the developer Emaar in Dubai were very high. That is why the client insisted on material and know-how from Germany. The task of Strukturmetall was to emboss a pattern (5WL) into the smooth stainless steel panels to increase rigidity and reduce weight. This ensures a higher stiffness and a specific reduction in weight.
