RECYCLING OF STEEL PARTS INCREASING

Ruukki Construction manufactures recyclable building products, whose condition and loading are monitored digitally.
As a building material, steel has always managed well, due to its lightness and resilient strength. It is also unsuitable as a growth medium for mould. Steel has recently found a new competitive edge. As the scarcity of raw materials increases and the significance of our carbon footprint is further emphasised, the need will arise to recycle steel parts of buildings, in addition to traditional steel. 

“In terms of megatrends, Asia is an area for new building, where the significance of construction efficiency is emphasised, and big changes will be seen in the construction value chain. Europe is an area of renovation, where the use of prefabricated components is expanding, and where recycling will also most likely be included in building design,” says Pekka Roivio, Ruukki’s Research & Product Development Manager.

A TRANSFERABLE STEEL BUILDING CAN ALSO BE BORROWED

Many municipalities have unpleasant experiences of schools suffering from mould, and regional day care requirements are changing quickly. Architecturally high-quality, transferable public buildings are growing in popularity. “Municipalities have begun lending easily transferable, adaptable buildings that suit individual uses. By looking at them, you would never think by they can be moved from place to place,” Mr Roivio relates. 

Ruukki Construction manufactures floor, roof and wall elements that have virtually no organic substances. “They don't absorb moisture, so mould doesn’t have a chance to grow there,” Mr Roivio adds. 

BROADER USE OF DIGITALISATION

According to Mr Roivio, the use of digitalisation during construction is going to increase: “Digital twins utilise in-service information also with respect to the status and condition of recyclable parts. A building part that has had good care and less strain often has both service life and usage value to spare. Smart components in structures are increasing: we, too, have a roof sensor on the way that will relate the condition of loading on the roof. This way, for example, snow load removals can be optimised. Extra sensors can easily be added to the system to monitor, for example, the moisture history of building shell structures.”

Especially in redevelopments and recycling, the popularity of steel is surely set to grow in the years to come. "In building design, total service life costs will be taken into consideration more and more, and this will inevitably increase the competitive capability of steel products.”
