Question for Metal guys

[az2tx]

I'm going to be building a 20x24 foot covered roof area. I plan on using 6ea 4x4 steel post one in each corner and one in the center of the 24 ft sides.
The roof will be a 3/12 and the ridge will run the 24 ft, the rafters will be
1 1/2 x 3" with a metal panel roofing.

Here are my questions.
What gauge post should I use?
What size beam should I use to carry the roof load, the span will be 12 ft.

Your input or suggestions would be great

Thanks

Unless you want the center posts, it is not needed. You can span 24' pretty easy

I would use 1/4" wall min. for post if freestanding. You could go lighter if you are sheeting some of the walls.

There are several metalplaces that have standard kits. They do the work on what is needed.

I got quotes from several and Metal Mart was the most reasonable prices.

You can span up to 25' with 6" perlin. It will probably be cheaper to eliminate the extra to post and upsize your perlin to 6", unless you need it for doors.

What about bracing ? With just a roof and open walls the winds could sdo a number on it I would think if it isn't braced fairly well

The structure will be able to withstand the wind shear (side wind) because the lack of sides. The biggest concern would be up draft which would try to tear the roof from the structure. Bracing will not help you on up draft but only on wind shear. It doesn't hurt to have bracing by any means. You can brace at the top corner of each post about 2' down and 2' over with some angle iron, pipe or perlin. Another method used in steel structures is placing a diagonal steel cable from the bottom of one post to the top of the next. Then do the same on the opposite side of the building, just reverse the direction.

Dont scrimp on wall thickness on any part of your project.

get a quote from a metal building supplier and they will engineer it and tell you what you need. your rafters seem a little small to me.

I was thinking about using 4x4" 1/4" wall for the beam, but it would probably be cheaper using purlins
