How should I hang a hammock from steel joists?

Question

Hi! I'm trying to hang a hammock on my balcony. There is an overhang above the balcony which I'd like to hang the hammock from. I started a small hole in the outdoor drywall material hoping to find a wood stud. Instead I found a metal floor joist.

Would anyone be so kind as to tell me how I should secure the hammock? My research into the types of joists suggests that some might have holes to accommodate plumbing and wiring. Should I try to find one and run a rope through it? Or do I use a self tapping s***w and treat the metal stud the same way I would a wood stud?

Any recommendations?

Thank you!

Answer 1

There must be some kind of expanding, moly-bolt that can handle the weight. I don't see how hanging a hammock would be feasible from what must be at least a 7 ft. overhang, though? Perhaps a self supporting hammock frame is in order or in some way of utilizing an existing railing?  

Answer 2

The metal framework most likely will not hold a hammock.  Most canopy framing is done with 20 gauge studs.  These are strong enough to hang the Densglas (drywall), but will definitely not support a hammock.

Can you anchor it to the walls?  If not, you may be best off using a freestanding hammock.  Hope this helps.

EDIT:  If it's part of the floor, you are probably looking at 16 gauge.  They are much stronger, and the depth (width) will give strength approximately equal to wood.  However, I would still hesitate to hang a hammock from it.  If you do, you will want to be close to the wall to reduce deflection.  That of course means there won't be much room for a hammock.  If you do decide to try, use a 1/4"-20 eye bolt, which you will need to tap.  Drill a 13/64" hole and use a 1/4-20 tap.  Good luck.
