[ News ]Steel: Reaching new heights

Expected to be completed in five years, construction on what will be the world’s tallest building in the Saudi Arabian coastal city of Jeddah is under way. At a height of over 1,000 metres and a total construction area of 530,000 square metres, the Kingdom Tower is expected to cost US$1.2 billion.

An estimated 80,000 tonnes of steel will be required in the building’s construction with the 160 floors accommodating a mix of residential, office space and commercial units. Furthermore, the 1 kilometre high building will feature the world’s highest observation deck on the 157th floor.

The Kingdom Tower’s design is both highly technological and organic according to its architects, Adrian Smith + Gordon Gill Architecture, with tapered wings producing an aerodynamic shape that helps to reduce structural loading due to wind vortex shedding. In addition, the building’s exterior wall will feature a high performance system that will minimise energy consumption by reducing thermal load. The new construction will take advantage of new and innovative thinking about technology, building materials, life-cycle considerations and energy conservation.

Kingdom Tower, Jeddah, Saudi Arabia

When completed, the Kingdom Tower will stand 173 metres taller than the Burj Khalifa in Dubai to become the world’s tallest building. The Kingdom Tower will have a total of 59 elevators, five of which will be double-deck elevators, as well as 12 escalators. It will be the centrepiece and first construction phase of the US$20 billion Kingdom City development near the Red Sea.

Even during periods of economic turmoil, the environment remains a key issue for our world.

By 2050, it is estimated that there will be two billion more people living in the world’s cities which, according to experts, will mean that world construction will grow by more than 70% and reach $15 trillion by 2025, outpacing global GDP. Part of the solution is to build with steel – 50% of steel is used in construction. With four people per house, this will mean providing 1,427 homes every hour, with most of them needed in Asia and Africa. How can such growth be made sustainable?

As most people are aware, steel is used in so many important applications, from bridges and other large constructions, trains and rail lines to industrial machinery, housing, offices, hospitals, cars, buses and bicycles, to name but a few examples. Steel delivers a number of unique environmental benefits, such as product longevity, recyclability, easy transportation and less raw material wastage. In addition, steel offers architectural and design flexibility due to its inherent strength, which allows large span distances and curves to be easily incorporated into designs.

Perhaps best of all, steel is 100% recyclable, without losing any of its properties or strength, and thus reducing the solid waste stream, which results in saved landfill space and the conservation of natural resources. Indeed, more steel is recycled each day than any other material. Even better, the steel industry as a whole has dramatically improved its energy efficiency over the past 30 years, cutting energy consumption by 50% per tonne of steel produced and substantially reducing carbon dioxide (CO2) emissions, also per tonne of steel.

The industry is always looking for ways to improve, and to that end a project is in place in the United States that explores the possibility of replacing carbon with hydrogen in blast furnaces. In addition, ULCOS, which stands for Ultra–Low Carbon Dioxide(CO2) Steelmaking, is a consortium of 48 European companies and organisations from 15 European countries that have launched a co-operative research and development initiative to enable drastic reduction in CO2 emissions from steel production. The consortium consists of all major EU steel companies, energy and engineering partners, research institutes and universities and is supported by the European Commission. The aim of the ULCOS programme is to reduce today’s CO2 emissions by at least 50%.

From a human health perspective, steel frames have proven ideal for the ‘healthy home’ concept. The incidence of asthma and sensitivity to chemicals is on the increase and steel frames have been used to achieve allergen-free and dust-free interiors. This requires techniques such as special sealing around windows, moisture barrier systems in the walls, extensive insulation, and whole house ventilation systems. Steel frames retain their original dimensions, which is a major factor in maintaining effective long-term sealing.

Steel is already being used to help manufacture lighter, more fuel-efficient vehicles as well as renewable energy infrastructure including wind turbines, solar installations, smart electric grids and energy-efficient housing and commercial buildings. Its economic benefits include its quick construction off-site, which means less site disturbance and waste, more usable floor space, e.g. thinner floors allowing for more stories in a building, the flexibility to re-configure buildings and steel has a long life with low maintenance, plus energy efficiency for lower operating costs.

New surface coating makes steel stronger, safer and more durable

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new surface coating that can make steel stronger, safer, and more durable. The coating, made from rough nanoporous tungsten oxide, is the most durable anti-fouling and anti-corrosive material to date, capable of repelling any kind of liquid even after sustaining intense structural abuse.

The team of Joanna Aizenberg, Professor of Materials Science at Amy Smith Berylson and core faculty member of the Wyss Institute for Biologically Inspired Engineering at Harvard University, first developed Slippery Liquid-Infused Porous Surfaces (SLIPS) in 2011 and has since demonstrated a broad range of applications for the super-slick coating. The new SLIPS-enhanced steel is described inNature Communications.

“Our slippery steel is orders of magnitude more durable than any anti-fouling material that has been developed before,” said Aizenberg. “So far, these two concepts – mechanical durability and anti-fouling – were at odds with each other. This research shows that careful surface engineering allows the design of a material capable of performing multiple, even conflicting, functions, without performance degradation.”

The biggest challenge in the development of this surface was to figure out how to structure steel to ensure its anti-fouling capability without mechanical degradation. The team solved this by using an electrochemical technique to grow an ultrathin film of hundreds of thousands of small and rough tungsten-oxide islands directly onto a steel surface.

“If one part of an island is destroyed, the damage doesn’t propagate to other parts of the surface because of the lack of interconnectivity between neighboring islands,” said Alexander B. Tesler, former postdoctoral fellow at SEAS, current research fellow at Weizmann Institute of Science in Israel and the paper’s first author. “This island-like morphology combined with the inherent durability and roughness of the tungsten oxide allows the surface to keep its repellent properties in highly abrasive applications, which was impossible until now.”

The material could have far-ranging applications, including non-fouling medical tools and devices, such as implants and scalpels, nozzles for 3-D printing and, potentially, larger-scale applications for buildings and marine vessels.

While a multitude of grades of steel have been developed over the past 50 years, steel surfaces have remained largely unchanged. “This research is an example of hard core, classic material science,” said Aizenberg. “We took a material that changed the world and asked, how can we make it better?”

This new academic research work shows how steel has the potential to become ever more resistant to corrosion protecting it and prolonging its lifespan in applications where it comes into direct contact with water.
