[SFDXA] Super Heavy-Duty 3" Support Post - 1/2" Wall Thickness

[Michael Raskin]

I recently purchased a 24’ long, 3” OD (2” ID) round steel DOM (drawn over mandrel) tube with .500” (1/2”) wall thickness, ASTM A513 (1020), which I had cut into three 8’ sections.  I used two of these 8’ steel tubes as a support tube (5’ in concrete, 3’ above) for two very large DX Engineering verticals on 160 and 80.  I have one 8’ section left available for purchase. The 8’ tube is super heavy-duty (Rockwell Hardness B80, yield 60,000 PSI) and weighs over 100 pounds.  It has been commercially painted with Rustoleum.  This is loads more stronger than a 2-1/2” (2.895” OD) schedule 80 galvanized steel thick-walled pipe you might be tempted to use.  For pick-up only, in Stuart. $100.
