THE FUTURE: DURABILITY WITH STEEL

Posted on: 20 December 2020

We previously wrote about the use of sustainable raw materials for concrete construction. Pelecon was the first in the Netherlands to apply “Freement” in the construction design of a building foundation. Freement is a recycled type of concrete. In addition to durable concrete, it is also increasingly common to use durable steel of higher quality in a steel construction.

Advantages of steel qualities S235 – S35

The material costs for the production of steel grades S235 – S355 are roughly the same. By continuously increasing the production of high quality steel, the costs converge. The current cost ratio in the market between S235 and S355 is approx. 2-5% more expensive for the higher quality. The strength capacity of S355 is 50% stronger compared to S235 steel. By using S355 steel instead of S235 steel in the calculation design, the steel weight of a building structure can be reduced by approximately 20-25%, which is a direct cost and environmental saving

Energy neutral

A steel construction element is dimensionally and wear resistant. Because it can be built tightly, the end result of the structure is airtight. Which, of course, together with good insulation and the installation of solar panels, ensures an ultimately energy-neutral building

Lower environmental impact

Steel is manufactured industrially, there is little or no construction waste. But there are more reasons why sustainable steel has a lower environmental impact.

1. De- and remountable

It is very easy to reuse steel. Then there must be a simple design from which the steel can be disassembled. At Pelecon we are already working within our latest construction designs to design the steel construction in combination with floor elements de- and remontabal.

2. Database for buildings

Another important part is the creation of a database for buildings that we are going to build now and in the future. The current buildings are fully BIM engineered. This means that all building elements can be easily traced back to size and quality. If the building is at the end of its life, the building elements can be selected by means of the BIM models. They can be given a second life in another building or work of art.

3. Biocoat

What also contributes to sustainability is coating the steel structure with an indoor climate by means of Biocoat. This transparent coating of steel structures gives the steel a robust and natural look. This coating is more environmentally friendly than traditional coatings. (www.circulairstaal.nl)

4. Skellet

A sustainable way of building can be done by applying the “Skellet building system”. A Skellet profile has holes on a grid of 25 mm that are used to connect the profiles by means of blind rivets. The Skellet building system therefore only consists of bolted and riveted connections that can be assembled and disassembled without damaging the connecting pieces. The result is dimensional stability and flexibility in design and during construction and the possibility to reuse the profiles. (www.skellet.com)

Positive influence on environmental savings

In short: Today’s steel constructions have an increasingly smaller impact on the environment during the production of the building components up to and including dismantling and recycling or reuse. Pelecon always takes durable steel structures into account when designing. After all, sustainability is a keyword for the future in construction!
