Mezzanine

[Dave Maxwell]

Building a mez in my shop and plan on having it 10x30 foot. The 30 will be running along an outside wall. Question is how far apart can the inside supports be? Not wanting a wall on the inside part. One side of the 30 will be attached to outside wall and 10 foot across from that I will need supports, but not wanting a solid wall

You need a structural engineer, he'll also tell you if the outside wall can carry the planned load. You'll want to sketch something out for him and tell him what materials so he has a straw man, then he'll tell you how wrong you are and how to fix it.

That said, big enough steel beam and you can span 30 feet, so you'd have just a post at each end. The size of the beam and posts will be based on the planned load.

Well if it end up not being possblein my pole building, I'll have a place for sale. It's useless to me without the storage area. I'll see if I can find somebody local that can look at it before I spend anymore money on it

I have a 40x40.

The back left corner I have a 10x14 room with 2x8 on 16" centers. I then spanned 14' with 2 2x12 crowned with 1/2" osb sandwiched between the 2 and 2x8s for the floor. At the end of the 14' span is 2 4x4 and then it spans another 12'. The 4x4s are part of the wall that goes 30' towards the front of the shop.

ive had no problems in the year+ it's been built.

Mine is 20x30 with no supports. It is the full width of the building (30') and along the back wall. Just size your beam accordingly.

A lot depends on what weight you plan to load the mezzanine floor with. For general use I think 2 x 8's on 16" centers will work for most applications. Have these sitting on 4 x 10" headers and 4 x 4 posts at 10' intervals.
I planned for heavy commercial usage and built my mezzanine with 2 x 12's at 16" o/c using 3/4" ply on the floor. Better too strong than too weak...Also make very certain that you anchor the floor well on the outside support wall, not just with nails but lag bolts and joist hangers.

When I put the mezz in my rental hangar, I set up 4 steel posts and built a wood on purlin deck. I tied two of the posts to the existing hangar structure only to prevent accidental racking of the mezz. No problems and when I moved out, took everything with me.

You will need a beam on top of the posts to support the floor. The size of the beam and the load it carries determines post spacing.

Pallet racking is a literal erector set, but most crossbeams are 8' long (I have some that were a custom something like 8'9") so you'd have a support every ~8' which may be more than you'd like.

If you got 36" wide racking you could do two runs 30' long with a 3-4' gap between them and floor it accordingly.

I mention it only 'cause it's easy to put up, will unquestionably handle any reasonable load you can put up there, and easy to tear down or reconfigure.

Plenty of threads here on pallet rack mezzanines

If you can weld more and more options open up. I've modified a lot of it for custom lengths, handrails etc

I just built a 30x50 garage and had a 12" I beam with center post on back wall and 14" I beam no center post 10' out from that. I am trying to figure out floor joist material and spacing. I am thinking of using C purlins welded to tabs at 16 OC. I think they are 14 Gauge 8x1.5 purlins. Any ideas or opinions on this idea would be greatly appreciated

1. No reason why people on this forum can't give you a VERY good idea as to what you need.

HOWEVER, that will not happen if you bail on your own thread!

You need to answer questions and engage.

2. You say the 'back' side, which is 30; long will be agaisnt a wall. How about the two "10 foot" sides? Also walls?

3. Pole barn? What size poles? Spacing?

4. What heights you talking about?

5. What are you planning on placing ON this mezzanine??? 10x30 is 300 sqft. 3 ton of **** is 20 lbs/sqft.

I'd expect a doubled 2x12 ledger attached to the wall, then the same size beam in the front with ONE pole, attached to the two otehr walls at the end, and 2x8 or 2x10 across might work.....but you should provide more info for a better idea,

The mezzanine guru here is bczygan (well IMHO anyways).

Here's some threads where he has helped others. Check this out: bcygan Mezzanine Threads

Anybody got some pictures of what they got or are building for a mezzanine? Im planning of building one too. Mine I need a 24' span. Pictures might help out ARD and others too. Thanks. BCD

I built this 30x40 mezzanine to take advantage of my shop height. Built 100% by myself. I even hoisted the giant LVLs up myself and set them in the 6x6 posts in the early AM hours. Its been a long process that I would get burned out on and then revisit later but this weekend I finally got it done. I am now planning to add onto it to cover half of one of the bays so I can put my pool table, shuffleboard and card tables up there.

If you go with C purlins, they don't have much lateral stiffness. At 10 feet you are good to some weight, but they will begin to roll over ar some point without blocking.

We made ours from a 30' travel trailer frame with parts in the middle. It's 8 x 30. We're using it for storage only.
