Construction is one of the most important steel-using industries, accounting for more than 50% of world steel production. Buildings - from houses to car-parks to schools and skyscrapers - rely on steel for their strength. Steel is also used on roofs and as cladding for exterior walls.

According to the UN's latest forecast dating July 2015, world population will reach 8.5 billion in 2030 and 9.7 billion in 20501..This will be accompanied by rapid urbanisation. As the need for buildings and infrastructure continues to grow worldwide, reducing consumption of natural resources and associated emissions is crucial for future sustainability.

Steelmakers around the world are increasingly providing construction solutions that enable energy-efficient and low-carbon-neutral buildings. These solutions reduce the environmental impact over the structures’ life cycle and help to extend their life span through design for disassembly and reuse.

Steel can provide the solutions to infrastructure and construction needs in developing countries and in climate resilient cities through enabling protective coastal and wind-resistant designs. While buildings currently account for about 20% of global greenhouse gas emissions, they also present many opportunities for reducing emissions and mitigating climate change.2,3

Not only is steel affordable, readily available and safer, its intrinsic properties, such as strength, versatility, durability and 100% recyclability allow for improved environmental performance across the entire life cycle of buildings. 

The advanced high-strength steels used in steel-plate applications also find uses in a number of related industries. Offshore oil rigs, bridges, civil engineering and construction machines, rail carriages, tanks and pressure vessels, nuclear, thermal and hydroelectric plants – all these applications benefit from the attributes of modern steels.

How steel is used in buildings and infrastructure

The possibilities for using steel in buildings and infrastructure are limitless. The most common applications are listed below4.

For buildings

• Structural sections: these provide a strong, stiff frame for the building and make up 25% of the steel use in buildings.
• Reinforcing bars: these add tensile strength and stiffness to concrete and make up 44% of steel use in buildings. Steel is used because it binds well to concrete, has a similar thermal expansion coefficient and is strong and relatively cost-effective. Reinforced concrete is also used to provide deep foundations and basements and is currently the world’s primary building material.
• Sheet products: 31% is in sheet products such as roofing, purlins, internal walls, ceilings, cladding, and insulating panels for exterior walls.
• Non-structural steel: steel is also found in many non-structural applications in buildings, such as heating and cooling equipment and interior ducting.
• Internal fixtures and fittings such as rails, shelving and stairs are also made of steel. 

For infrastructure

[ 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.

Discover how practical stainless steel kitchen island surfaces can serve as the ultimate spot for food preparation.

   There's something about a stainless steel kitchen island that exudes a flair often found in a true chef's kitchen. It makes sense, of course, given the fact that stainless steel is durable and easy to clean, making it an ideal choice for a homeowner seeking an extra space for food preparation. But no matter the reason, the stainless steel kitchen island can be a useful addition to many kitchen areas.

Kitchen Islands: Beautiful, Functional Design Options

Stainless steel surfaces often work well in a modern, functional kitchen design. While some islands incorporate an all-over stainless steel surface, others will designate a specific spot of the island for the material and use other surfaces, like wood, to complete the island.

Some kitchen island carts or freestanding kitchen islands are also made with stainless steel, making them particularly useful in small kitchens that require a bit more space for food preparation.

Stainless steel kitchen islands work beautifully with pops of color, like red paneling or citrus orange diner-style seating. These color bursts help to balance the otherwise simple nature of a stainless steel surface.

If you do choose a stainless steel kitchen island, then it is important to match accessories like a sink or drawer handles to the material for an overall finished look.

New Choice: Stainless Steel Kitchen Cabinets

Gain insight on stainless steel kitchen cabinets, an alternative material used in modern kitchen design.

    Stainless steel is a material prominent in most modern kitchens designs. Homeowners seeking an updated kitchen often desire stainless steel appliances and sinks, and stainless steel kitchen cabinets work well with this look.

Historically used in restaurants, laboratories and for medical storage, stainless steel cabinetry has moved beyond its industrial beginnings and is now found in high-end home kitchen designs.

While you can get a very sleek, angular look with stainless steel kitchen cabinets, it does show fingerprints and scratches easily so you want to make sure you are comfortable with a non-perfect surface if your kitchen is used frequently. Fortunately, over-the-counter stainless steel cleaners are readily available so that fingerprints can be easily wiped away.

Besides being easy to clean, stainless steel is a durable and sanitary material—two very appealing characteristics for a frequently used room such as a kitchen. For the earth-friendly homeowner, stainless steel cabinets are considered a green product, meaning they are recyclable, non-toxic and easy to clean without the use of harsh chemicals. Additionally, steel cabinets are a great pick for outdoor kitchens, since they hold up quite well against the elements.

stainless steel is everywhere in the kitchen

Stainless steel is a more expensive material than wood. One option to achieve the look of stainless steel while avoiding the cost is to install wood or particleboard cabinets covered in metal door and drawer fronts.

Stainless steel kitchens may seem cold and institutional to some. Pairing stainless steel cabinets with warmer materials such as wooden flooring, glass inserts, or even a kitchen island made of a warmer wood can be more appealing to the eye and provide a unique feel to your kitchen design.

Copper or bronze hardware or accents can also break up all of the silver tones that stainless steel kitchen cabinets provide. Whether you are seeking a truly sleek modern space or a more transitional look, using steel as an alternative to wood in your kitchen cabinetry can give a breath of fresh air to your home.
