At BAU, the world's leading trade fair for the construction sector, from 17 to 22 April in Munich, ArcelorMittal's business units will present a wide range of products on offer: from facade solutions and load-bearing structures to roof structures for photovoltaic systems.

Robust, sustainable, and as eye-catching as possible

Steel as a material is playing an increasingly important role in resource-efficient construction. Steel is versatile, fully recyclable, and – thanks to innovative technologies – can be manufactured with a smaller carbon footprint. The use of steel products with reduced CO₂ emissions represents further progress towards a climate-neutral construction industry.

"This year, our focus is on the topic of sustainable construction with steel, highlighting the role that low carbon emissions steel can play in reducing the carbon footprint of the construction sector. Manufacturing methods are changing, which means the use of renewable energies and scrap are increasing. As a durable, infinitely recyclable, but also very versatile material, steel is suitable for any use in the construction industry. And it is an important material in the energy transition, with low-carbon emissions steel needed for wind power or photovoltaics. Visitors to BAU will be able to see this for themselves," says Tapas Rajderkar, Chief Marketing Officer of ArcelorMittal Europe – Long Products.

Carbon emissions reduction thanks to XCarb® steels

Sustainability, circular economy, and ArcelorMittal's XCarb® range are in focus this year. This brings together all the group's manufacturing processes, products, initiatives, and innovation projects aimed at reducing CO2 emissions. XCarb® recycled and renewably produced steel is made in an Electric Arc Furnace (EAF) using 100% renewable electricity and up to 100% scrap, significantly reducing the carbon footprint of steel buildings. Emissions can be as low as 300 kilograms CO₂ per tonne compared with over two tonnes for steel produced conventionally. In the construction of an industrial hall, for example, steel that is recycled and produced with renewable electricity can save as many tonnes of CO₂ as the total steel tonnage required for the building envelope and supporting structure, without changing the construction method or the established building process.

Sustainability goes hand in hand with quality at the world's leading steel and mining group. In addition to the aesthetic aspect, the performance and recyclability of the materials and the construction elements used have an impact on the life cycle assessment of a building. The use of high strength steels contributes to a reduction in the carbon footprint. For example, for the same load-bearing capacity, the carbon footprint of a beam can be reduced by 15 to 20%. When using a composite deck instead of a conventional precast concrete one, the reduction is up to 30%.

A wide range of applications in construction

With the Granite® product family, ArcelorMittal offers a range of organic coated steels for building envelopes with more than 120 colours and textures, guaranteed for up to 40 years. For facade substructures, solar mounting structures, but also cable trays, composite floors, and many more applications, Magnelis® metallic coated steel resists corrosion three times better than regular galvanised steel. Both products are available as XCarb® recycled and renewably produced.

Special roof panels for photovoltaic systems

A few years ago, a solar/photovoltaic system was still a "nice to have", but today it is a standard feature and has even become mandatory for new commercial buildings. ArcelorMittal specialises in the installation of photovoltaic modules on roofs and will be showing its portfolio at BAU. Whether renovating existing buildings or constructing new ones, Ondatherm Solar® roof panels offer simple and quick installation for photovoltaic systems, are robust, and provides a high level of thermal protection. Various flexible solutions are available to customers and builders for mounting the modules.

Sustainable supporting structures

ArcelorMittal will also present its solutions for load-bearing structures at BAU. Cofraplus® 80 composite floor profiles are approved by building authorities as prefabricated steel floors and have a significantly lower carbon footprint compared to prefabricated concrete slabs. For structural applications, high strength HISTAR® steels provide cost and material savings. The weather-resistant Arcorox® steel grades with natural corrosion protection have a long service life and are already being used successfully in bridge construction projects.

BAU 2023

XCarb® Recycled and renewably produced is now in stock in Singapore and available for the South East Asian market. Continental Steel, a major stockist in Asia, has recently purchased 6000 tonnes of XCarb® recycled and renewably produced sections. Through combined efforts between ArcelorMittal Europe – Long Products and the ArcelorMittal International Singapore office, Continental Steel are convinced they will gain a competitive advantage by being among the first distributors in Asia to promote and sell low CO2 emissions steel.

In Singapore, the demand for green steel in the construction industry is growing. Buildings account for over 20% of carbon emissions in the country, so reducing CO2 emissions in this sector is a key lever to drive large-scale decarbonisation. In this context, ArcelorMittal Europe – Long Products and the ArcelorMittal International Singapore office's combined efforts in offering XCarb® recycled and renewably produced sections convinced one of our best stockist customers in Singapore to become the first in export sales to join the action.

Value creation by enhancing engineering and preserving the environment

"We are delighted to be the first in Asia to offer ArcelorMittal’s recycled and renewably produced steel that has been certified,” says Melvin Soh, Executive Director of Continental Steel Pte Ltd. “This product is in line with our philosophy of maximising value to our customers, value that is created by enhancing engineering and preserving our environment. Continental Steel is committed to playing a responsible role towards a net-zero future, promoting actions aimed at mitigating climate change. We encourage all stakeholders in Singapore’s built environment to take advantage of this availability and to join us in being responsible for our environment.”

Prateek Aggarwal, Business Area Head – Asia at ArcelorMittal International, said:

“We are very pleased to work with ArcelorMittal Europe – Long Products and Continental Steel on bringing sustainable and innovative steel products to the Singapore market. This order of 6000 tonnes of HISTAR® high strength steel with XCarb® recycled and renewably produced certification is our testimonial to support green building initiatives in Singapore and will further help in the endeavour of low carbon footprints in the construction industry.”

Continental Steel and ArcelorMittal: partners for years

Through the ArcelorMittal International Singapore office, Continental Steel in Singapore purchased 6000 tonnes of XCarb® recycled and renewably produced sections in steel grade HISTAR® 460 / S460M for its stock. The sections are column sizes UC356x406 and HD400 ranging from 237 kg/m to 900 kg/m, which will be produced in the Differdange plant in Luxembourg.

Continental Steel will offer the first and largest stock of XCarb® recycled and renewably produced sections in South East Asia from their warehouse in Singapore. They are convinced their move will help to strengthen their market position in supplying sections to construction projects in the region.

Continental Steel and ArcelorMittal Europe – Long Products (through the ArcelorMittal International Singapore office) have been partnering for years already. As an example, ArcelorMittal HISTAR® beams are at the heart of the Jewel Changi Airport in Singapore. Today, thanks to their loyalty and trust, Continental Steel are helping to spearhead the South East Asian market with XCarb® recycled and renewably produced, which fits perfectly with the HISTAR® range. When lean design using high strength HISTAR® 460 sections is combined with XCarb® recycled and renewably produced steel, designers can drive low carbon solutions. Pairing a low embodied carbon manufacturing process with high strength steel can deliver very high carbon reductions.

ArcelorMittal's next joint projects with Continental Steel will be to deliver steel sections to upcoming major infrastructure developments like underground stations, expressways, and aviation hub expansion projects in Singapore.  Pioneering with green steel and ArcelorMittal's XCarb® recycled and renewably produced sections is a step for Continental Steel towards gaining a competitive advantage.

In May 2022, ArcelorMittal International was awarded the highest rating at Singapore Green Building Council’s Leadership in Sustainability awards. The certificate acknowledges ArcelorMittal’s HISTAR® high strength structural steels for their outstanding sustainability due to the usage of 100% scrap steel and the EAF production route.

ArcelorMittal awarded the highest rating

In Singapore, as in many countries, the government is pushing hard for sustainability. Buildings in Singapore account for over 20% of carbon emissions and consume more than a third of the nation’s electricity. Singapore is already one of the most solar-dense cities in the world, but this is not enough. All efforts by companies, especially in the construction sector, must be encouraged and the most efficient solutions rewarded.

The Singapore Green Building Council’s Leadership in Sustainability awards recognise professionals, organisations, and construction projects that have made significant contributions to the development of a green, sustainable built environment.

ArcelorMittal International was among the 20 winners of the year and was awarded the highest rating.

Singapore Green Building certification for ArcelorMittal’s HISTAR®

ArcelorMittal International received the Singapore Green Building Product Certificate SGBP 4275 from Singapore Green Building Council for HISTAR®.

“This certification shows that ArcelorMittal is environmentally responsible. It is a great recognition for our efforts towards carbon neutral steel,” says Tan Yi Zhou, Technical Sales and Business Development, ArcelorMittal International. “I would also like to highlight that ArcelorMittal is the only steel supplier on the list that has structural steel beams and columns certified by SGBC with a 4-tick certificate.”

90% reduction with the perfect low carbon partners: HISTAR® and XCarb® recycled and renewably produced

ArcelorMittal International received the SGBP 4275 certificate for ArcelorMittal steel manufactured according to the ETA-10/0156 standard. With 100% scrap steel used in the electric arc furnace route, HISTAR® emits 524kg CO2/tonne for the life cycle analysis modules A1-A3.

ArcelorMittal can even go one step further in decarbonising HISTAR® steel products by manufacturing them with renewably produced electricity with the XCarb® recycled and renewably produced label. When lean design using high strength HISTAR® sections is combined with XCarb® recycled and renewably produced steel, designers can find the perfect low carbon solution. Pairing a low embodied carbon manufacturing process with high strength steel can deliver carbon reductions of up to 90% (for HISTAR® 460).

Therefore, the next step for ArcelorMittal International in Singapore is to obtain another certificate to differentiate XCarb® recycled and renewably produced (with its low CO2e emissions at 333kg CO2/tonne) from the current SGBP 4-tick certified steels at 524kg CO2/tonne.
