Steel is one of the icons of modern architecture and symbolises strength, versatility and structural integrity in the eyes of architects. From 19th-century American skyscrapers to world-famous landmarks, steel has changed the look and feel of cities and towns around the globe. Let’s dive into the history and art of steel architecture, find out why many choose to work with it and get a feel for its international influence.
The History of Steel in Architecture
There are traces of steel that date back to ancient times, but modern-day steel production has its roots firmly in the 1850s — this is where steel production started to forge its stellar reputation in the building world. One of the earliest and most famous examples is the Crystal Palace, originally built in London’s Hyde Park in 1851. Housing the Great Exhibition, the sprawling building was made using the nascent materials of steel and glass. These materials reflected the sense of burgeoning modernism that was inside the building. Another key steel building that showed the growing eminence of the material is London’s Ritz Hotel, completed in 1906, which was the world’s first steel-forged hotel.
However, steel wasn’t the only thing that changed architecture in England in the 19th and 20th centuries. Across the Atlantic in America, the Empire State Building, a symbol of technological and economic strength, was built from steel in 1930. It was then the tallest building in the world, reflecting the emergence of steel being used in iconic buildings worldwide.
Here at Carnegie Steel Buildings, we draw inspiration from the legacy of Andrew Carnegie, a pioneering force in the steel industry in the early 20th century. His vision and entrepreneurial spirit transformed steel production, making it a cornerstone of modern construction. Carnegie’s innovative approach and commitment to quality laid the foundation for monumental structures that have stood the test of time. Our company continues to honour his legacy by producing high-quality steel buildings that reflect the same principles of durability, excellence and innovation that Andrew Carnegie championed.
Modern Steel Architecture
Steel has continued to be the backbone of many major buildings, with the robust material shaping countless skylines and cities — including designs by some of the world’s most famous modern architects.
Some architect’s names evoke images of hyper-modernity — slick, clean and visually stunning. The use of steel in these buildings provides fantastic examples of the high-end results that steel structures and cladding can achieve. At the top of this list is Zaha Hadid, a world-famous architect known for using concrete, glass and steel. One example of Zaha Hadid’s outstanding and world-leading steel design is at St. Anthony’s college campus, Oxford University.
How Steel Enhances Architectural Engineering
With a history still dominating skylines today and contemporary architects using designs with both steel structures and steel cladding to convey a sense of modernism, the story of steel architecture is as rich as it is long-lasting. But there are plenty of practical reasons why architects and structural engineers love working with steel — let’s discuss a few of the main benefits of building with steel.
Increased Strength and Durability
Steel buildings can withstand a lot and provide outstanding protection against various environmental factors such as wind, earthquakes, freezing temperatures and fires. This durability gives steel buildings a longer lifespan when compared to other construction materials, as it is hard to warp or damage.
Flexibility
In addition to durability, steel has become an almost ubiquitous building material due to its flexibility. These two properties allow more creative designs — giving architects the freedom to create strong structures as well as being able to use steel in organic and undulating designs. A fascinating example of this can be found in Tokyo, where a building with steel cladding was designed to replicate the movement of fabric. The option to make strong but unique shapes with steel in architecture offers endless possibilities, keeping it a part of cutting-edge architecture.
Sustainability
Steel is 100% recyclable, making it a fantastic choice for architects and structural engineers who want to incorporate sustainability. Steel can be reused and offers fantastic energy-saving properties, as it can deliver high-quality insulation to reduce heating and cooling throughout its lifetime.
Economic Benefits
In addition to saving people money on energy bills, steel is also a cost-effective option for construction and maintenance due to its durability — saving on repairs that a weaker material might incur.

Steel Architecture and Design
We’ve highlighted the many examples of steel in design and what makes it an excellent option for construction — but what makes steel the material of choice for many contemporary architects?
Versatility in Design: As mentioned above, steel’s strength and flexibility allow architects to make their creative visions come to life. It’s ideal for projects that need large spans of material to create large spaces or that call for less-conformist lines. In addition to being able to create unique designs, steel can support heavy loads with minimal material, and this allows for open and airy spaces, which is a popular aesthetic in modern architecture.
Best Projects for Steel: With many benefits, steel is well-suited for projects needing strength, durability and the ability to achieve aesthetic appeal. Building projects such as high-rise buildings, stadiums and large industrial structures are just a few ways steel is commonly used in buildings today — but with steel, the sky’s the limit when it comes to designs and architectural ideas. This makes it perfect for boundary-pushing design and stand-out projects that define a city’s identity.
Why Architects Choose Steel: With this in mind, architects choose steel for its strength, long-lasting nature, sustainability and ability to give buildings a strong visual appeal through its versatile nature. This means architects seeking modern and iconic designs can create new and innovative buildings with sustainability and longevity covered.
Benefits over Concrete: While concrete is another material conventionally used in construction and building design, steel offers some important advantages. Steel structures are lighter, which reduces foundation costs and boasts higher strength-to-weight ratios, enabling architects to achieve more sprawling or open designs with less material. On top of this, steel, as we’ve already discussed, is a more sustainable and versatile material — allowing for greener and bolder designs to be created. Concrete is in stark contrast to the recyclable steel, as it has been coined “the most destructive material on Earth”, and is responsible for 8% of global CO2 emissions.
Another “pro” of steel vs concrete is that, with some design projects, steel can offer faster construction times due to prefabricated components and ease of assembly on-site. This is highly different to concrete, which requires curing time.
In short, steel’s versatility, strength and sustainability make it an indispensable material in modern-day architectural design. Working with steel offers distinct advantages over concrete, including faster construction times, greater design flexibility and reduced environmental impact. As the construction industry continues to evolve, steel will remain a cornerstone of architectural innovation and sustainability.
Steel Engineering Challenges and How to Overcome Them
Although used widely with great success in steel framing and building designs, working with this material has a few drawbacks. These include corrosion, vulnerability to high temperatures and potential structural issues when designs are not up to standard. Here, we break down each issue and highlight solutions.
Corrosion
Steel is susceptible to corrosion due to dampness and moisture or through chemical interaction.
Solution: To prevent this and to make your steel extremely durable, protective coatings can be used. This type of steel will provide long-term corrosion resistance in environments that are conducive to corrosion.
Vulnerability to High Temperatures
Exposure to extreme heat can affect the strength of steel, as it causes the metal to lose its stiffness. Therefore, elevated temperatures can cause steel to deform, leading to collapse and endangering lives — this can pose a structural failure risk in specific circumstances.
Solution: Architects can take advantage of fire-resistant coatings, insulation and structural fire protection measures to ensure their steel designs have a low chance of being affected by high temperatures. Fire-resistant coatings provide a barrier, delaying the temperature rise of the metal and keeping its strength intact.
Structural Issues from Poor Design
Steel can withstand a huge amount of weight with relatively little material — but only when it’s used properly in a well-considered design. Badly designed steel structures may experience structural issues such as excessive deflection or buckling through insufficient load-bearing capacity. Design errors or inadequate structural analysis can lead to steel underperforming and causing the above issues.
Solution: These checks are the foundation of any seasoned architects’ or structural engineers’ practice, and advanced modelling and simulation techniques can be employed to highlight any potential issues in a design alongside expertise and knowledge.
