What is Sustainability?

Sustainability means meeting our own needs without compromising the ability of future generations to meet their own needs. Steelmakers around the world are increasingly offering intelligent steel construction solutions that enable energy efficient and low-carbon-neutral buildings. These solutions are highly material efficient and recyclable. They reduce the environmental impacts over the structures’ life cycle and help to extend their life span through design for disassembly and reuse.

Here are some facts that showcase some
of the industry’s notable results:

Raw Material Conservation


Steel can be Recycled over and over with no loss of performance.

Steel is the most Recycled Material on the planet more than all materials combined.

Water-Use In Steel Production

Approximately 90% is cleaned and returned to its source.

The World Steel Association states that worldwide, the steel industry has reduced energy consumption since the 1970s in the manufacture of steel by 50%.
This directly relates to a reduction in greenhouse gas emissions.


Steel construction material can fulfill many of the sustainability demands of:


LEED – the industry’s Environmental Product Declaration for cold formed steel (CFS) framing helps architects and engineer document impacts and achieve credits required for LEED and other green building certification program


Strength to weight ratio of steel is Highest of any building material


CFS framing contains at least 25% recycled steel. Steel is continually and completely recyclable.

One of the main reasons steel is widely considered environmentally friendly is its recyclable nature. Steel is the most recycled material in the world – more if it is recycled every year than all other materials in the world combined, with more than 12 million tonnes being recycled every year. The metallurgic properties of steel mean that when it is recycled, no degradation occurs whatsoever. This means that it can be melted down and reused an infinite amount of times without being compromised in anyway.

The recyclable nature of steel greatly reduces the environmental impact of creating it from raw materials. For example, making steel cans from recycled steel uses 75% less energy than producing them from raw materials.

Recycling 1kg of steel keeps 2kg of greenhouse gases out of the atmosphere. Recycling steel also diverts these products from landfill, and enables the material to be reprocessed, thereby conserving raw materials. For every tonne of steel recycled 1131 kg of iron ore, 633 kg of coal and 54 kg of limestone are saved.

Less Wastage

One of the biggest factors that makes building with wood and other materials so detrimental to the environment is wastage in the form of unusable offcuts. Steel is custom-made by steel fabricators like us, made-to-order for each and every project right down to the smallest detail. This means the wastage is basically nonexistent. Furthermore, the wastage created by building with wood requires removal in some respect (i.e; removal of offcuts by truck or using water) – yet another strain on the environment.

The efficient nature of building with structural steel also means the construction process as a whole is simplified. Less manpower and a faster-construction rate reduces resource consumption as a whole. Remember, when it comes to the conserving planet, every little bit counts.

Energy Saver

Building a steel framed house is great for your energy bills both in summer and in winter. Firstly, steel’s inherent strength means that it can support more thicker, more efficient insulation.

In winter, this means that you will use far less energy trying to warm up your house with heaters and air conditioners.

In summer, steel framed houses provide better air quality and reduce humidity, meaning that dehumidifiers and air purifiers are not needed, further reducing your energy costs and your carbon footprint at the same time.

Reusing Water and Slag

Water is one of the most important elements for steel production. It is mainly used in the cooling process, as well as for cleaning and descaling. While this water does become contaminated in steel production, most of the impurities can be removed through special filtration processes.

Making of 90% the water reusable.

Another bi-product of steel production is slag, a stony waste product separated from metals during the smelting of ore. In the past, slag was dumped by steel manufacturers as it was considered unusable and this had some devastating impacts on the environment. However, today slag is almost entirely repurposed for use in cement.

Reducing Air Pollution

The steel industry is extremely eco-conscious, especially when it comes to carbon emissions. Since the 1960s, the industry has halved its carbon footprint, and its dust emissions by even more. These numbers are constantly falling.

Steel Lasts Forever

Once you build with steel, you won’t have to build again.

Steel will stand up to everything from high winds and rain, to fire and earthquakes. Termites and other boring insects and no threat to it either.

Steel won’t crack, warp, twist, split or rot, it can be designed to resist rust and
vandals. It will virtually last forever, further reducing the impact of raw material
consumption and the widespread felling on trees which is so detrimental to the

So, is steel eco-friendly?
