I am adding a very small balcony to an upstairs studio in our house, and part of it has to be supported on one end only. The total sq footage of the addition is 1/4 circle with 50" radius (It is to connect two right angle sides with a new curved "side". I am considering using 1.5" x 1.5" and 1/8" angle iron to strengthen/support the 2x4 or 2x6 used as the balcony support. This angle iron would extend a maximum of 50", but an additional length would extend back under the current upstairs and be resting on load supporting walls. Im thinking this extension under the current 2nd story floor would be around 4-6'. Would this reasonably support say 300 lb???

The short answer to your initial question is ... No the materials you selected won't support the load.

It's a fuzzy line between what a person should advise a person on without seeing things, and things that it'd be better if they didn't. If this were a perch for say a flower box that is a foot off the ground and nothing but ground below it. then you'd probably be given all sorts of input.

First thing a person would ask would be for more clarification on this construction. Without being there to see exactly what you're doing and the condition of all structural members and fasteners etc. and a pile of other issues... nobody could give you an accurate assessment of the feasibility of your design.

Then there are the legal issues. You build this because someone tells you it's all-good over the internet without ever seeing the thing and it collapses. with a stack of babies and kittens and puppies on it. They all fall 50 stories and kill some sort of endangered species that just happen to be strolling below at that same time. Imagine the trouble the person who said it was all-good would be in after a mess like that. the media and attorneys from all over would have a field day with that.

Doesn't sound like a big project and an engineer in your area. familiar with any of your local codes. shouldn't charge much to advise you on this. They might suggest some channel instead of angle and say the steel is cheap so why not beef it up. They might show you ways to give the design a neater, or more professional looking appearance while also making things stouter? They'll almost certainly tell you to design for as many hefty folks as you could squeeze on the thing and then double or triple that. Especially if there are gonna be puppies and kittens and babies on it also.

Better off going that route. spend a little bit more and keep from getting burnt down the road.

Good luck,
Bob

Yes you have seen various questions regarding angle iron....we try to stray away from structural questions pertaining to living and working environments..

Due to the liability involved we try to steer you to your local building codes and professional engineers that can review your requirements.

Good Luck

I want to reinforce what "Marky" said. Since this is an occupied structure you must use your local building codes. Depending on where you live and how busy the local inspectors are they can refer you to someone or if in their opinion your case is a simple modification they may tell where you can find the information you are looking for.
IF there is any doubt in your mind find a licensed engineer or architect for advice as a minimum, or have them create plans for you to follow.
