Pole barn truss

I posted a couple of weeks ago that I bought some angle iron pole barn trusses.
Someone ask if I would post some pictures and dimensions when I got them.
Well I do not have them up yet but I did go pick them up yesterday.

They are made of 2 inch angle iron. (most I have seen are 1.5 inch)
The stabilizer bar at the bottom is welded in. (most I have seen are bolt in)
They use 5/8 inch threw the post bolts with a 4 inch wide plate that goes against the post. (most I have seen use the angle against the post with 1/2 inch lag screws)
The top and bottom cord is 16 inches apart with 1 inch angle iron webs.
The plate on the post is 18 inches long.
From the peek to the bottom of the cross brace is 36 inches.
They exceed my 110 mph wind load and are rated for 15 foot span if you use strong enough purlins.

So with these 24 foot trusses with a 4/12 pitch on a 10 foot post.
You would have about 8 foot 8 inchs clearance at the post. (10 feet minus 16 inches to bottom cord)
And about 11 foot clearance max in the center of building. (10 feet plus 4 foot rise minus 3 feet down to cross brace)
All of these measurements are +/- a inch or so.

The only thing I have seen on other trusses is a place to put a 2x6 brace on the bottom cord.
These do not have that bottom cord cup.
I guess they are using the brace welded in feature to make up for that.
I may add one on the bottom brace so I can X brace these trusses.

I have seen others for $300.
These were $185 plus the bolts.

When I read your specs these trusses are rated for a 15 foot span. And then you ask a question stating you are using them for a 24 foot Truss. Just how wide a span are you planning? I read they are for a 15 foot span with a 4+foot over hang--little less counting for the width/thickness of the wall.

These 3- 24 foot trusses will build a 24x30 barn with proper purlins.
15 foot span OR 15 feet between each truss may be a better way to say it.
With that kind of span they recommend metal Z purlins but 2x8's would work also.
It is a little far for 2x6's unless you add blocking.

I am supposed to look at some used ones in the Baton Rouge area, but what you have may be a better deal! I'm trying to put up a 30X36. Would you mind sharing the info where you purchased them? I'm in MS, just north of Mt Hermon, LA. Brother-in-law lives near you, in Robert.

Thanks John.
Please continue to post pictures as they go up!

So this will be a mono slope building, and you have 6 pieces of truss that will bolt together to form 3 24 foot long trusses, with 15 feet between them for a 30 foot by 24 foot mono slope roof?

The building will be open, or doors, on one side with an 11 foot high by not quite 15 foot wide opening each, and the back side of the building will be about 8 foot 8 inches of headroom.

The numbers and pictures get a little confusing, just want to get it right in my head.

No Paul this is a 4/12 slope gable roof.
The 3 foot side of the truss bolts together and it slopes to both sides.
Sides can be any height you want. I plan on going about 10 feet.
3 post down each side spaced up to 15 feet apart.

The roof looks like this.





And a picture of the inside of a enclosed barn.

Gary; My e-mail should be open on this post.
Send me a e-mail and I will give you all the info.
This place is closer to you than Baton Rouge anyway.

You didn't mention snow load. ; )

Is there a website you can share with the rest of us? That is an interesting truss design.

Nice looking building with little material used. If I built one like that here by the big lake it would be work great until the first north west wind brought in the "lake effect". Couple hours and she would be flat. 58 LBS snow load here. Easy to see 24-30 inches of new snow in a given winters morning. Costs tons more money to build a barn here. Some days I question if it is worth it living here in "Gods Country" as Dad called it. Al

I see! Buildings look so flimsy down there, up here in snow country we have to do things a little different. Thanks for the pics!

Looks like very nice building, by flimsy I don?t mean it?s bad, it?s just such lighter construction works there, good for you.

Sure.
I got these from Reeds Metal in Brookhaven Ms.
They have several other locations across the south.
While there are other places a lot closer to me it was worth the 100 mile trip for what they saved me.
My salesmen (Greg) was very helpful in getting me what I wanted.

We worry about wind load not snow load.
But these will hold snow load; just not at these big spacings.
With 1 extra truss I you could go to 10 foot spacings and get a snow load for most.

These trusses were made popular in the chicken broiler house industry.
