Does the AS/NZS 3679.1 rolled-in mark need to be on both sides of a Universal Beam?
AS/NZS 3679.1 doesn’t stipulate where the rolled-in mark needs to be positioned on a beam. It’s generally placed on one side of the web or on one flange, not both. However, it needs to be no more than 4m apart, so a 4m-plus long beam should have at least one rolled-in mark on it somewhere, i.e. on either the web or flange. Liberty OneSteel Universal Beams have the rolled-in mark on the web, although some manufacturers place it on the outside of the flange.
What are the details of the radii on the milled flanges of all Universal Sections (UCs) from 200UC46 up to 310UC158?
Liberty OneSteel’s Universal Sections are produced with a nominal radius of 0mm on the edges. They are nominally a right-angle edge with no prescribed radii.
How do I obtain the security code for Composite Analysis Software?
