ArcelorMittal is continuously improving the efficiency of its steel products to enhance strength so designers can further optimise their structures, leading to better evaluations in sustainable building certifications.
- High strength steel sections, among them HISTAR® S460, that allow for section reduction and, consequently, weight reduction while still offering the same load bearing capacity
- Heavy plates made from high strength steel grades (up to S460)
- Bare (Amstrong®) or metallic coated (Hyper®) flat products with yield strengths up to 700 MPa and higher (Amstrong® Ultra up to 960 MPa) used as light gauge steel profiles
- Composite flooring sheets to reduce the weight (and height) of floors in multi-storey buildings
- Organic and metallic coated steel sheets for facades and roofing applications - thin material which can be combined with high strength steels up to 450 MPa to optimise load bearing capacity – offering aesthetics and weathering resistance
- A wide variety of profiled sheets, panels, and sidings for lightweight facade and roof cladding
- Cold formed profiles for light steel framing for new buildings, renovations, and extensions of existing buildings
Weight optimisation is gaining popularity in construction applications as it has a direct impact on the carbon footprint per building m².
Optimising a construction’s overall weight goes hand in hand with material, cost, and environmental impact savings and has an overall positive effect on all construction related processes, such as:
- Building design: slender structures and lighter building envelopes require smaller foundations
- Logistics: smaller and lighter components reduce transport needs
- Handling, storage, and assembly on site
Reductions in materials, costs, and transport consequently reduce CO2 emissions, which lessens the construction’s environmental footprint.
Thanks to its high strength to weight ratio, steel has considerable advantages in comparison to other construction materials as it allows for the fabrication of relatively light and small construction elements that still comply with required strength and resistance criteria. By using high strength steels (HSS), building components can further be reduced in size (and therefore weight) without compromising load bearing capacity.
The weight reduction of steel construction products is of special interest for renovation and rehabilitation works. Costly upgrading of existing structures and foundations can be avoided or limited by using lightweight steel elements to repair or retrofit existing constructions.
