Need Box Steel Specs for Boat Support
Hello everyone. I have 3 X 3 X 3/16"' box mild steel and I want to store
my boat on crossbeams supported only on the ends. I have enough steel that I could double the beams by welding.
I was wondering if anyone could tell me the dead load capacity of this steel.
For a good ball park idea of span I haven't figured it out yet, but it will be anywhere up to 140 inches across or less to allow the trailer to pull out and leave the boat on jack stands.
