Spec Piping rectangle pipes rotated around the Z axis

Hi All

Is there any way in Spec Piping to create a rectangle pipe (in our case say 450x50 cable tray) that is rotated around the Z axis

We are using Spec Piping to run our cable trays (and was planning to integrate our HVAC system) in our designs (motor Yachts) but do not have the luxury of running the cable trays in 90 degree rotations

So most of the time we run our Cable tray, pipes, and HVAC ducting down the sides of the Vessel which means that we have to rotate out trays around the Z axis see below

at the moment we are using non Spec Piping to do this but for the long term this is not the route we want to take

any help greatly appreciated

Thanks

David
