King Cross is a built-up / fabricated steel section. Standard sizes can be made by welding 2 T-Beams into the web of a hot rolled IWF, forming the shape of a cross. Non standard sizes are made entirely by welding steel plates.
King Cross's are generally used for structure column and steel piling foundation. When used as a column, King Cross can bear higher axial load than it is of standard IWF / Queen Cross due to its mechanical properties and high cross section area.
Compared to standard IWF / H-Beam, King Cross has higher Moment Of Inertia. To increase the slenderness capacity, higher Moment Of Inertia is required to avoid any buckling on the compression member. The Moment Of Inertia of the Y and X axis is almost the same, thus resulting in no weak axis.
