hey guys, I built a nice A frame out of 2x4's and plywood a couple of years ago, its been nice with poured concrete anchor at one end and a large boulder I bolted at the other. Problem is the A-frames are getting weathered and worn, I'd like to build one out of aluminum I beam but its a about $300 bucks just for the I beam. Is anyone out there selling anything like a 42" aluminum I beam that will support a backyard slackline? Thanks!

What you need is pressure treated lumber. You'll find it at any building suply store. Way cheaper then metal.

Good input, thanks I wrote my request poorly, I'm not looking for a aluminum I beam I'm looking for an A-frame made out of aluminum, somebody's gotta make something that fits?
Slackline Joe: Hey Joe, thanks for your help I asked for and took your advice a couple of years ago and setup slackline in my backyard. I think you said it'd take a couple weeks to learn, it was a couple of months but I got it. Great fun and exercise! Thanks again. Scott

In reply to: Actually a standard wood weather sealant would help and be a lot more cost effective.
And less lightning rod-esque. :lol:

It's not that we couldn't make something that would work well, it's more that you wouldn't want to see the cost type of thing. Shipping would be fairly rough and we'd have folks complaining that "Hey, I could have made that myself!" type of thing.
Building aluminum to actually take loads wouldn't be difficult, it's just not that cheap to do and it wouldn't actually save a lot of weight when compaired to a couple 2x4's.
As for the couple months thing, it's a your mileage may vary type of thing. How much time you spend learning has a lot to do with it, but having someone to coach you through the first bit makes a huge difference (usually walking 1/2 a line or more in an afternoon).

i'mma have to agree with those who said the aluminum is good in theory, but not in practice.
for the cost of an aluminum setup--even if you can find a setup that doesn't need to be custom done--is gonna get you years and years of wooen a frames, especially if you paint or treat them...
plus, if you ever come up with a mod or an improvement, doing it in wood is gonna be hella cheaper and easier and more forgiving than doing it in aluminum.
