Optimised steel structures for a low carbon future15 February 2024
The construction industry is the world’s largest consumer of raw materials and the built environment accounts for between 25 and 40% of global CO2 emissions. The sector is responsible for nearly 40% of annual raw material use and around 39% of the total primary energy use. These numbers are set to increase.The most promising construction material in terms of low emissions and increasing circularity is steel. Although the steel industry is among the highest-emitting industries (about 7% of global carbon dioxide emissions), the carbon footprint of its manufacturing process has decreased over the last 25 years and today new low-carbon alternatives are cutting emissions faster than before. The circularity of steel, enhanced by the possibility to upcycle, unlike other materials, and its low-carbon alternatives have resulted in its use in innovative projects driven by sustainability.Efficient design of steel structures is key, designing with end-of-life in mind and specifying low-carbon alternatives. With design choices playing an important role, we need to rethink the design approach from a circular, more holistic, and therefore more sustainable perspective. The research paper ‘Why optimised steel structures will help reduce embodied carbon’ provides a brief overview of the steps being taken to decarbonise steelmaking and examines the impact of the construction sector on global emissions. The main objective of this paper is to put forth easy-to-use tools to help designers reduce the embodied carbon of their projects while offering guidance on evaluating sustainable solutions.Technical article

Education wrapped in steel17 May 2022
Education escorts us throughout our entire lives – as do the buildings in which we acquire our knowledge and skills. We recollect their architecture, interior design, pieces of furniture, and even their smells. Some have impressed us more than others, but none of them have left us indifferent. In our memories, these buildings are profoundly connected to our experiences and emotions, including the people we connected with there.Over the last few decades, education has evolved and so have the requirements for educational buildings. Architectural design has significantly increased in importance, technology has conquered interior design, and user comfort is a key concern, all of which are important factors accompanying the learning experience. Architecturally attractive buildings not only express the prestige and status of institutions but contribute to a sense of wellbeing for their users.Project news
Floor systems are made up of galvanised decks or galvanised pre-coated decks. These profiles, carefully combined with materials such as concrete, thermal and acoustic insulation, plaster, and wood, form advanced construction systems intended for all types of structures where their effectiveness and reliability are proven.
ArcelorMittal’s family of flooring solutions includes:
Cofraplus® floor decks: Trapezoidal steel sheets with open ribs and specific embossment to ensure composite action with concrete. Thanks to their geometry, they are stackable for easy storage. Cofraplus® is the best solution for most projects involving spans up to 4.5 m.
Cofrastra® profiles: Thanks to their undercut geometry, an especially high adhesion between the steel and the concrete can be achieved. Technical equipment can be installed quickly and easily beneath the slab thanks to an adapted fixing system.
Cofradal® integrated floor system: Made of steel, thermal insulation, reinforcement, and concrete. Two to three times lighter than conventional concrete floors, it provides a high load capacity and bridges long spans economically without additional support.
Cofraplus® 220 additive steel deck: Easy installation at high speed and outstanding resistance at reduced weight are the main features of this new system, which is particularly suited to all column-beam structure projects without intermediary joists.
Floor systems in steel
ArcelorMittal's range of floor construction systems is the most comprehensive on the market and offers the right solution for any kind of project and technical requirements. It consists of both well-established systems and innovative solutions which reflect recent developments in regulation, design, and installation.
The floor systems serve as a self-supporting formwork, and they resist construction loads and concrete weight. They are simple and quick to lay and easy to handle. Easy cutting and quick interlocking of the ribs contributes to site productivity. Thanks to their specific design, which optimises composite action with concrete, ArcelorMittal’s floor profiles contribute to weight reduction of structures.
After installation, the floor decks create a continuous working platform that allows site workers to walk on them safely once they are fixed to the supports.
The web-based design tool Cofra5 is free of charge and offers assistance in the calculation of ArcelorMittal’s composite flooring solutions.
