Steel is one of the most versatile and commonly used materials on Earth, with a huge range of uses and properties. To that extent, it is used in a selection of amazing steel buildings and structures (you can see some of those here). In this post, we’re going to celebrate some of our favourites.
Walt Disney Concert Hall, Los Angeles
Designed by the famous Frank Gehry, the Walt Disney Concert Hall is home to the LA Philharmonic Orchestra and was completed in 2003 after years of work. Consisting of numerous panels of stainless steel, it was built at a cost of $274 million. Many of the panels were initially matte, but some had reflective properties which caused problems for local residents; eventually the panels were sanded to reduce the glare.
Willis (Sears) Tower, Chicago
The Willis Tower in Chicago was once the tallest building in the world when it was finished in 1973. Visited by over one million people every year, it is made with a steel, tube-like structure and rises to 1730 feet.
Sydney Harbour Bridge, Sydney
Stretching a distance of 1149m, Sydney Harbour Bridge has a steel through arch design and carries vehicles, pedestrians and rail carriages. The arch is one of the largest in the world and, on hot days, it can increase by as much as 7 inches. In total, the estimated weight of the steel used in the bridge is around 53,000 tonnes.Burj Khalifa, Dubai
Now the tallest building in the world, the Burj Khalifa stands at an amazing 829.8m. Taking a little over five years to complete, it uses a bundled tube design that means it contains only half the amount of steel as the Empire State Building. Amazingly, the spire itself contains 4000 tonnes of steel.
Brooklyn Bridge, New York
Finished in 1883, the Brooklyn Bridge is one of the oldest suspension bridges in America and, perhaps, one of the most famous in the world. With a thick steel structure, the bridge took over 10 years to complete.
