Take Britain for example，The construction and operation of buildings is responsible for almost half of the UK’s carbon emissions, half of its water consumption, around a third of its landfill waste and a quarter of all raw materials used in the economy. This means that the UK’ s sustainable development targets cannot be met without a fundamental change in the construction industry. National targets for greenhouse gas emission reductions in both the operation and construction of buildings and the drive to a circular economy present a huge challenge to the construction industry – a challenge which the steel construction sector is playing a major part in overcoming.

Steel fabrication

All steel components are manufactured in the controlled environment of a fabrication factory, there are many strict standards. In this environment, steel parts can be easily standardised, tested and certified. The waste in the production process can also be reused.

Off-site manufacture is more efficient, faster, learner and safer than site construction. It also yields high quality products with fewer defects that require less 'snagging' on site, leading to saving in both time and money.

Steel recycling

Manufactured from the most abundant element on earth, iron, steel can be recycled or reused endlessly without detriment to its properties. This feature makes steel valuable at any stage of its life cycle. In some country , the average recovery rate of all steel structure products is 96%, which is much higher than that of other materials. Besides, recycling steel is ‘true recycling’, in which substitutes primary steel. This is unlike many other construction which are used into lower grade applications.

Speed of construction

A shorter construction programme reduces disruption and disturbance around the site. Speed of construction delivers an economic benefit too, which is fundamental to sustainable development. The shorter on-site period reduces the cost of preliminaries, reduces the period of financing and provides a quicker return on investment from rent or sale.

Adaptability

When buildngs are demolished, a lot of waste may occur. The large span of steel structure means that steel structure building has great space and strong adaptability. It’s easy to remove or add parts. Otherwise, The steel frame itself is also easy to adjust, and it’s light weight means that extra floors can often be added without overloading existing foundations.

Steel structure are commonly used to renovate buildings for example behind retained facades. In this way the historic value, character and resources of the facade are retained and the building structure can be reconfigured to create open, flexible internal space that meets modern client requirements and increases rentable area.
