Jumbo Sections


Australasian designs do not need to be constrained by the range of AS/NZS standard sections. There is a wide range of hot rolled Jumbo sections manufactured to International standards offering substantial benefits in terms of size and strength.

Jumbo Columns
AS/NZS 3679 hot rolled column sections are manufactured up to: 310UC 158, a 327mm x 311mm column weighing 158 kg/m and maximum flange thickness of 25mm.

HL extra wide flanged beams
HE wide flanged beams
UB Universal Beams
W wide flange beam

Jumbo Equal Angles
Traditionally equal angles have been manufactured up to 200 x 200mm. Due to increasing demand for more efficient towers for windmills and pylons for power transmission, ArcelorMittal have developed L300 x 300 and L250 x 250 equal angles in thicknesses up to 35mm.

They are unique with no peer, there use enables stronger lighter more efficient structures.

New Equal Leg Angles

ArcelorMittal manufacture quality hot rolled beam sections up to 1100mm deep within their Eurpoean, British, and American section ranges.

For reference the following sections are manufactured:

HL 1100R 499, a 1118mm x 405mm beam with primary axis section modulus of 23150 (10)3 mm3 and maximum flange thickness of 45mm, this is equivalent to American section W 1100 x 400 x 499.

HE 1000 x 584, a 1056mm x 314mm beam with primary axis section modulus of 23600 (10)3 mm3 and maximum flange thickness of 64mm, this is equivalent to British section UB1016 x 305 x 584

These jumbo columns can be manufactured in HISTAR with 450MPa yield strength throughout, this provides an unfactored section capacity more than 3 times greater than the above 500WC.

W wide flange beam specifications

Jumbo Hot Rolled Beams
AS/NZS 3679 hot rolled beam sections are manufactured up to: 610UB 125, a 612mm x 229mm beam with primary axis section modulus of 3230 (10)3 mm3 and maximum flange thickness of 19.6mm

European wide flange columns HD sections provide sizes up to: HD400 x 1086, a 569 x 454 column weighing 1086 kg/m and flange thickness of 125mm, this is equivalent to American section W 360 x 410 x 1086.

Standard welded columns, which incorporate welding and fabrication and have steel grade limitations, allow larger sections up to: 500WC 220, a 480mm x 500mm column weighing 440 kg/m and maximum flange thickness of 40mm.
