Fabricated Bars are a lot of work, joints are beveled, welded then braced with 4mm laser cut plates.
Can be dropped off a three story building !
Can lift 100, 150, 200 – Longer ramp may be needed also.
Lift heights are center to center so a 100 lift is 100 clear space etc.
For tray back utes where a longer bar is required FAB bars are the strongest way possible as the distances per piece are shorter.
