Super Jumbos

Heavy Sections



Technical information

Super Jumbos are extra heavy rolled wide flange sections with up to 140 mm (5 1/2 in) flange thickness and weigh up to 1377 kg/m (925lbs/ft). They are available in very high strength steels including ASTM A913/grades 485, 450, and 345 MPa (70, 65, and 50 ksi), ETA - 10/0156/Histar 460, EN 10025/S460M and in normal strength steel grades (355 MPa).

Reducing cost & weight

ArcelorMittal offers heavy rolled wide flange sections with up to 140 mm flange thickness, available in very high strength and normal strength steel grades. An outstanding feature of these very high strength steels is their low carbon equivalent values allowing for easier processing by fabricators. As such, preheating before welding can usually be avoided and leads to substantial time and cost savings.

When the design of an element is not governed by deflection, higher strength steel enables an average of 20% weight and cost reduction on the structural elements. These savings apply also to the carbon footprint. Steel sections have an infinite recycling life and a 99% recovery rate.

Super Jumbos have been successfully used in columns, trusses, out-riggers, and belt trusses for various projects around the world including One World Trade Center in New York City (USA), the Shanghai World Trade Center (China), and the top structure of the Burj Khalifa in Dubai (U.A.E).
