I refuse to buy a bolt together POS from Home Depot when I own MM140- even if it's $500 in labor.
Is 1.5" x 1.5" square A513 tubing overkill or inadequate? What wall thickness will suffice? Am I WAY off base in materials selection?
I got a rough idea of materials cost by getting an online quote from metalsdepot.com. Metals Supermarket will likely be my supplier and I haven't a clue about what they'll charge for this type of material- they're website is a bit shy of functional?
A513 Steel Structural Square Tube 1-1/2 X 1-1/2 X 16GA (.065 wall) 48' = $93
A513 Steel Structural Square Tube 1-1/2 X 1-1/2 X 14 GA (.083 wall) 48' = $118
A513 Steel Structural Square Tube 1-1/2 X 1-1/2 X 11 GA (.120 wall) 48' = $136
