Girt Spacing

[Dmgoetz23]

I’m building a 75’ x 27’ x 16’ tall metal building. My walls are built using 2x6 studs 32” OC with a double studs at section joints (every 16’).

Trying to determine what spacing I should use for my girts. I plan to use a 2x6 girt at bottom and at top, then use 2x4 girts every X inches. I see people using 24” spacing but that seems like overkill.

Can I use 36” spacing? Thoughts?

Thank you

24" spacing is set for a 4' sheet of OSB for your sheathing. If you can find sheathing that is 6' wide I guess 36" would fine for the girt spacing...

I’m not planning any sheathing. 26ga metal attached to girts.

Depends on the wind you believe you will get. I did 2' spacing for both purlins and girts. 2x4's are pretty cheap and it only adds strength.

I ended up with about 30ish inch spacing between girts on my walls. No need to stick with standard “centers” if you are just hanging metal. I took the total distance, deducted for thickness of wood and made the girts evenly spaced. I then cut a couple of 2x4s to that length and used them as spacers to hold the girts up and screw off.

Man I was trying to figure out what "Girl spacing " was.....need to wear my glasses more!

Your studs are 32" oc they ultimately carry the wind load. Are the girts inset (between the studs) or continuous (outside the studs) ? with 32" oc vert supports it really doesn't matter! But, for pre engineered metal buildings with 26 ga panels our standard girt spacing was 5 ft on center. Think about it, for 30 psf snow load with 26 ga panels- purlin spacing is 5 ft. Wind uplift may require closer spacing tho. Basically, place the girts where convenient to your method of construction or insulation situation. 4' pieces of rigid insul. between the girts makes a good system.

If you haven’t already you need to install shear bracing. The sheet metal is not rated or designed to provide shear value.
