Metal trusses for pole barn

[oosik]

Farmer down the road about 30 miles built a pole barn for more of his hay. His trusses looked like Peter 315's except they were made of galvy steel. Don't know if they were commercial manufactured or it the guy built them himself. This was five or six years ago and the structure still stands.

thats called a ladder truss around here.....mostly used for floors but I've seen it used for roofs......the only thing I would want to check out is that it has been engineered for the specifics of the building.......generally you want like materials to be with like materials.....so steel trusses with steel posts.....wood trusses with wood posts...reason is movement of differing materials as well as the connections between the two.......not saying it can't or shouldn't be done just saying make sure an engineer has analyzed it and signed off on it for the specifics of your building.........Jack

Has anyone used this style of truss ? Sure gives you complete openness to the roof where as wood trusses take that space up. Still looking at all my options for structures. I have a Red Iron quote from Renegade Steel for a 30x50x16 for $20,000 installation not included.

What's the question? People use these kinds of trusses regularly. Bottom line is how many $/sq.ft. you want to spend for your building. My personal preference is all steel buildings - generally better build quality and consistency vs field carpentry. Around here its cheaper to ensure an all steel building than wood or wood/steel.

Are you planning to build this by yourself? The trusses are lighter and easier to handle than steel beams. Steel beams can be cheaper to use.

We used some of those one time. Customer purchased them. Every time I tried to pick one up it wanted to fold in half. Had to clamp a 2x6 to it. The 2x6 purlin sat in a U that wasn't very tight with just a nail holding it in place. And if you can drive a nail horizontally through that U and 2x6 then through the U again you're a better man than me.

Maybe I was missing something.

Wasn't the World Trade Center Building designed by Engineers??
If you need an engineer for a pole building then you better have him put it up too.

Just wondered if anybody has built with these type trusses. Steel buildings are nice but you have to make sure you put all the doors and windows in you want. As it all has to be figured in the engineering layout. You don't have the flexibility to change or add items as it then has to be re-engineered. I have a quote for $21,000 for the building awaiting a quote from the erector for labor.

The purlin holders come pre-drilled with 2 holes on each side then use screws or nails to secure.

I've saved these guys since they are not too far away, and they list prices.


I've also priced wood trusses, and they are cheaper. And then I've built quite a few 24 foot trusses, which isn't too bad, but to go bigger, I'm debating on the metal ones for the ceiling height, or wood ones with a flat ceiling and blown in insulation. Wood trusses, flat ceiling and blown in insulation will be the lowest cost by a significant margin, but it's also the most time consuming to build.

I have a Morton Building, somewhat East of you, - in Massachusetts.
Morton drilled 16"(?) diameter holes, and dumped two bags of Sakrete in each hole - dry!
Put the 6x6 posts in the hole, filled the hole, and built the building (36' x 48')
That was 34 years ago.
Building is just as good today as it was then.

I'd be interested in hearing more about this. What is your pole spacing? I figure with 48 the long way it's probably 8'. A 16" hole isn't too bad, you could still do that with a post-hole auger. I don't see too many pole barns around here, the soil is full of rocks. You go down a foot and there might be a boulder the size of a car. When I build fence I put the posts where they want to go, not where I want them.
