The application of weathering steel sculpture in World Expo

The National Pavilion of the Grand Duchy of Luxembourg at the Shanghai 2010 World Expo has an overall rust color, because the construction material is a special steel called weathering steel. Weathering steel is also called Corten steel, its special feature is that, exposed to the natural environment, through the action of air, rain, etc., the steel surface will automatically form a protective layer of corrosion resistance, no need to paint protection, the life of the material is more than 80 years. The corten steel is supplied by ArcelorMittal's Shanghai representative office, the Chinese headquarters of the world's largest steelmaker, ArcelorMittal, based in Luxembourg. Following the use of weathering steel for the facade of the Sino-French Center at Tongji University in 2004, the Luxembourg Pavilion was used again. When finished, the Luxembourg Pavilion will feature a natural primary color of weathering steel, while the interior walls will be made of fir wood. The new green steel and natural fir wood create a sculptural castle, which is not only artistic, but also understands the contemporary concept of environmental protection and sustainability. At the same time, it also portrays the image of Luxembourg, which is closely related to steel - for more than 100 years, Luxembourg has been known for its exquisite steel technology, and the steel used in the construction of the Eiffel Tower in Paris came from Luxembourg. The weathering steel used in the Luxembourg Pavilion will also be imported from Luxembourg. In addition, the weathering steel used to construct the entire Luxembourg Pavilion can be 100% recycled after the pavilion is demolished.
The Australian Pavilion at the Shanghai 2010 World Expo is made of red ochre weathering steel. A rolling, wavy facade of weathering steel plates represents Australia's coastline and its resource advantage in iron ore. The raw material for weathering steel is sourced from mines in western Australia and produced by local factories. The museum specially placed a circle of natural ores around the exhibition hall. The floor tiles around the Australian Pavilion are all red, and the raw materials of these floor tiles are also produced in the red land belt, which is transported by more than ten containers across the sea to Shanghai. Inside and out, red does not regret that hidden combustion only represents nature, but also reflects the concept of "industry" and "city".
