Wherever you look in the built environment, steel is there. From deep foundations and tunnels to landmark bridges and building envelopes, steel provides the strength and versatility these structures rely on. ArcelorMittal develops construction steels that help builders span further, build higher and adapt to tomorrow’s world.
For the construction market, which represented 20% of our revenue in 2025, we offer’ the most complete range of grades and specifications of structural steel, façade, ceiling and floor systems, sheet piles solutions for foundations and underground car park systems, steel plumbing solutions and a complete portfolio of reinforcement products. This includes rebar developed specifically for areas with high seismic activity, and steel fibres for tunnelling and other infrastructure projects.
Steligence®
Rethinking building design from the ground up.
Introduced in 2018 following extensive, independently peer-reviewed R&D, Steligence® is ArcelorMittal’s flagship, science-driven approach to construction. Led by CEO Olivier Vassart and a multidisciplinary team of engineers, architects, and construction experts, and supported by 13 patented steel solutions, Steligence® promotes a holistic building concept that integrates structure, envelope, interiors, infrastructure and lifecycle into a single system rather than treating them as separate components.
Projects delivered using Steligence® achieve at least 15% lower total cost of ownership than concrete alternatives, while consistently attaining higher BREEAM and LEED ratings.
Building envelopes. Engineered from the inside out.
As the world’s leading steel and mining company, ArcelorMittal applies advanced material science to building envelopes, where performance and design intersect. ArcelorMittal Building Solutions, its dedicated construction division, delivers technically advanced systems by managing the full value chain, from steel production to finishing and logistics. Its portfolio includes high-strength coated steels, pre-painted and galvanised substrates engineered for durability in extreme conditions. Flagship ranges such as Magnelis® and Granite® offer exceptional corrosion resistance, long service life, and design flexibility, making them a trusted choice for architects, contractors, and developers worldwide.
Building structures. Engineering strength. Enabling speed.
Steel is the material of choice for structural frames across high-rise, commercial, residential, industrial, and public buildings. ArcelorMittal delivers a comprehensive range of sections, heavy plates, and high-strength grades, supported by advanced R&D and Constructalia®. Solutions such as HISTAR® enable lighter, more efficient designs, while Angelina® beams provide long spans and flexible layouts. Steel structures can be erected up to twice as fast as concrete, accelerating delivery timelines. With XCarb® recycled and renewable steels reducing CO₂ emissions by up to 65%, ArcelorMittal offers structural solutions that combine efficiency, adaptability, and sustainability.
Building interiors. Smarter floors. Better spaces.
ArcelorMittal interior steel systems optimise space efficiency, reduce floor depths, and support flexible layouts for modern buildings. Solutions such as Cofraplus® and Cofradal® composite floor decks deliver high load capacity with minimal thickness, while CoSFB systems further reduce structural depth and costs. The portfolio spans façade interfaces, ceilings, flooring, plumbing, and reinforcement applications. Magnelis® coated light steel framing ensures durable, precise partitioning, while Estetic® coated steels provide high-quality finishes for interior surfaces, combining design versatility, long-term durability, and full recyclability.
Infrastructure. Built to last. Built to connect.
Infrastructure projects require materials that perform reliably in extreme conditions, from deep foundations to transport and energy networks. ArcelorMittal delivers one of the world’s most advanced infrastructure steel portfolios, engineered for durability and long-term performance. Solutions include seismic-resistant rebar and steel fibres that enhance strength, safety, and construction efficiency. Sheet piling systems such as AZ®, AU®, and HZ® provide versatile options for marine and civil applications. EcoSheetPile® Plus, made from 100% recycled scrap using renewable energy, reduces CO₂ emissions by up to 85%, enabling resilient, cost-effective infrastructure built for decades of service.
