These hairpin legs are advertised as 3 steel rods each leg, well their not rods, they are hollow, might be steel on the outside, but hollow inside.Advertised as able to hold 220lbs each leg and with all 4 legs, 880lbs, I'm not too sure about that, if they rods and not hollow rods they might be able to take 880lbs, but being hollow I would not try that much weight.
