Cost & weight reduction
ArcelorMittal offers heavy duty hot rolled large flange profiles with a flange thickness up to 140 mm, available in very high strength or normal steel grades. An outstanding feature of these ultra-high-strength steels is their low-carbon equivalent, which allows for easier processing by manufacturers. For this reason, preheating before welding can generally be avoided and this leads to significant time and cost savings.
When the design of an element is not governed by deflection, high strength steel allows an average reduction of 20% in weight and cost of the structural elements. These savings also apply to the carbon footprint. Steel profiles have an infinite recycling life and a 99% recovery rate.
Super Jumbos profiles have been successfully used in columns, trusses, barbells and truss belts for various projects around the world, including the One World Trade Center in New York (USA), Shanghai World Trade Center (China) and the tallest structure of the Burj Khalifa in Dubai (UAE).
Super Jumbos are extremely heavy wide flange profiles with flange thickness up to 140 mm (5 1/2 inches) and weigh up to 1377 kg / m (925 lbs / ft). They are available in ultra-high strength steels including ASTM A913 / grade 485, 450 and 345 MPa (70, 65 and 50 ksi), ETA-10/0156 / Histar 460, EN 10025 / S460M and in standard strengths (355 MPa) .
