Because angle has more structure... And it has more surface area to sink heat.hey why does everyone use angle alum for their frames? would two 48" pieces of 1/8" aluminum sag or droop in the middle if there are three qb's and a driver mounted to it?
Yes, 1/8 inch aluminum will sag. Angle aluminum will not sag, and if you get architectural angle aluminum (1/16) its lighter as well.hey why does everyone use angle alum for their frames? would two 48" pieces of 1/8" aluminum sag or droop in the middle if there are three qb's and a driver mounted to it?
1/16" tends to sag with enough weight. I recommend 1/8" for sure.Yes, 1/8 inch aluminum will sag. Angle aluminum will not sag, and if you get architectural angle aluminum (1/16) its lighter as well.
Sure if you hang twenty pounds from them. They'll certainly support the 3 pounds that a 320H driver weighs without sagging. We're talking about 3 QB's and a driver here.1/16" tends to sag with enough weight. I recommend 1/8" for sure.
3/4 x 1/8 flat stock may sag under its own weight at 48 inches. With three pounds of driver it will definitely sag.I was going to use two pieces of 48" in order to mount three boards between them. at first I was looking at angle aluminum, but now I'm thinking about using 3/4" wide, 48"long 1/8" thick flat aluminum and then using a piece of angled alum at the ends to connect them all.
Wanna save some more? Step out of HD and check out this place:I went to HD today just to check out the different options. 1/8" and 1/16" flat bars have way too much flex imo. however I think the 1/8" is overkill for the angle. 1/16" seems like it would be plenty sturdy and save some $ and be lighter and easier to handle.
when it comes to 3/4" vs 1" vs 1.25" vs 1.5", I think the 3/4" is good enough, once again saving $ and overall weight of the fixture.
You're a GOD. THANK YOU FOR THIS LINK. Holy shit that's a good deal.Wanna save some more? Step out of HD and check out this place:

Can't believe how inexpensive these people are... Too bad they don't do heatsinks.
Hell yeah man that's an awesome find.Wanna save some more? Step out of HD and check out this place:

3003... No need for anything else. If you don't care about price though, get the perty 5052.Ok so that website uaac.us has three different types of aluminum in the size that I want. (.75"x.75"x48", 1/16" thick)
Here are my options with total price for the quantity I need
1- Aluminum Architectural Angle : 6063-T5 type aluminum. $78
2- 3003 type aluminum angle : $61.20
3- Aluminum Anodized Angle, 5052 type aluminum "These are a fabricated angle and the color is dark bronze. These are considerbly stronger and lighter than our standard 3/4 in angle. The color is only on the outside of the angle. The inside of the angle is clear anodized." $126.36
what would you guys recommend?? (the price difference is non factor, just threw it in there)
Agree, just get the least expensive - extra strength is a waste, its not like you're going to be doing chin-ups on your fixture.3003... No need for anything else. If you don't care about price though, get the perty 5052.
