Steel: The Latest Architecture and News

One of the most important elements in architecture are the vertical circulations that are translated into elevators or stairs, and although some offices decide to approach it in a discreet way, some others choose to pay specific attention to it and turn it into a sculptural piece. Helicoidal staircases are some of the favorites when it comes to focusing attention and in our collective conscience we keep some iconic examples, as is the case of the staircase in the O'Gorman House, this piece gave a certain character to the work and it is almost impossible to imagine it without it.

The construction industry is one of the largest in the world, and cement and concrete are literally the building blocks of its success. Evolving from prehistoric caves to today’s towering skyscrapers, concrete structures have and will continue to be vital components of modern civilization, providing long-lasting, reliable support for buildings, roads, bridges, tunnels and dams. So much so that concrete is the most consumed material on Earth, second only to water, while the steel used to reinforce it is by far the most commonly used metal. But this doesn’t come without high environmental costs: concrete accounts for 8% of global CO2 emissions, much of which come from the extraction and transportation of aggregate materials such as sand, gravel and crushed stone.

Stairs are often an inevitable part of a building's DNA. Nowadays, staircases not only serve the function of practicality but are also a showcase of their own kind, especially if paired with a color that is guaranteed to grab attention. Among warm colors, red is considered to be the most powerful one. On one hand, it evokes feelings of joy and energy, and on the other, feelings of alertness and danger. Red can stimulate a whole range of emotions. Therefore, its usage should be attentive, delicate, and thought out.

Mies Van der Rohe and Lilly Reich’s German Pavilion for the 1929 Barcelona International Exhibition is known as the most written-about modern building. But no matter how many times the pavilion is redrawn for analysis, there are always new angles from which to interpret it. Identifying its capacity to redefine the German image, while genuinely introducing new strategies that continue present in contemporary architecture projects are two key elements of the architects’ intentions behind their design strategy.

'We have to get away from the coldness of functionalism. It is a mistake to believe that to understand the problem of modern architecture it is enough to recognize a necessity for rational solutions. Beauty in architecture, which is a necessity and finality for our time as for past periods, cannot be attained unless we can see beyond simple utility when we build.' – Mies Van der Rohe

Metaphorically, building bridges equates to creating new opportunities, connections, and paths. The first bridges likely formed naturally with logs falling across rivers and natural depressions, though humans have also been building rudimentary structures to overcome obstacles since prehistory. Today, technological advances have made it possible to erect bridges that are both impressive and sculptural, playing a key role in transportation and connectivity. Usually needing to overcome large spans, with few points of support, bridges can be quite difficult to structure. But when is the bridge more than a connection between two points, instead resembling a building with a complex program? How can these 'bridge houses' be structured?

Shortly before the First World War, Harry Brearley (1871-1948), who had been working as a metalworker since he was 12 years old, developed the first stainless steel. Seeking to solve the problem of wear on the inner walls of British army weapons, he ended up obtaining a corrosion resistant metal alloy, and added chrome to the cast iron. The invention found applications in almost all industrial sectors including for the production of cutlery, health equipment, kitchens, automotive parts, and more, replacing traditional materials such as carbon steel, copper, and even aluminum. In civil construction, this was no different, and stainless steel was soon incorporated into buildings.

For a small child, understanding the concept of time and its passage is very difficult. As a result, children are often impatient when expecting something or confused when trying to remember something from the past. They live in the present, and learn the notion of time only little by little. But accepting the passage of time, and the reality of aging, is something that plagues us even as adults. The lucrative cosmetic and plastic surgery industries show how humanity seeks to control or deny the passage of time, an urge that has proved to be relentless.

After centuries of using wood for the development of window and door carpentry, the Rationalism of the 20th century began to adopt a new material for these purposes: steel. Driven by industrial production, and promoted by architects such as Adolf Loos, Mies van der Rohe, and Le Corbusier, steel was evolving to generate increasingly thin and resistant frames. However, efficient and low-cost materials, such as aluminum and PVC, gradually began to replace its widespread use, increasing the size of the frames and losing steel's "clean" aesthetic when applied to a growing architecture of large glass paneled facades.

At present, new technologies have refined their production processes, developing minimal profiles of high rigidity and precision, which take full advantage of the transparency of the glass and deliver new comfort and safety features. We talked with Jansen's experts to deepen our understanding of their application in contemporary architecture.

Cracks, which could be classified according to their thickness as fissures or fractures, are serious problems in the construction industry that can negatively affect aesthetics, durability and, most importantly, the structural characteristics of a project. They can happen anywhere, but occur especially in walls, beams, columns, and slabs, and usually, are caused by strains not considered in the design.

The use of steel in architecture is considered as one of the most innovative construction developments in history, allowing architects to create structures in scales they never thought they could. Fast-forward a few centuries, and steel remains as one of the most crucial materials in architecture. But there is a lot more to the material than just tensile strength and durability, some architects were well-aware of steel's potential and transformed it into lighting fixtures, facades, decorative elements, and finishes.

Here are 15 projects where architects looked beyond steel as structural support and explored its diverse possibilities in architecture.
