Industrial Shelf replacement shelving.

I have this industrial shelfing unit from yeas ago thats been in my shed for years. the shelfs are made of particle board and over the year the humid air as made all these sag. I could easily replace with plywood or even a bunch of cheaper cut boards. But newer shelfs have wire and or plastic shelf boards. Buying just those is the cost of a new shelf.
Any ideas that are better then ply or boards? the size is 24"x48"

Watching this thread closely as I have two of these in my garage suffering the problem with the sag. I was thinking about cutting some plywood shelves.

me too but with how expensive plywood is, i was thinking about cutting some 24"L 1/2x 6" pine boards, hell even sealing them. i think the ply will suffer the same thing over time.

Replace particle board with MDF. It's denser and stronger that basic particle board.

if MDF gets wet, it's done. you would have to paint it

Wonder what the cost would be with the MDF mentioned and two flat bars under each shelf to help support any sag compared to plywood?

Maybe see if you can find some wire shelf inserts. My husky rack came with them and I put thin luan on the bottom rack to store plastic liquids.

I had the same issue with sagging in the middle and replaced it with plywood. That was over 2 years ago and no sagging since. It was 19/32 size if I remember correctly.

I've had 4 of these since 2017. The shelves are some sort of plastic laminate. There is no sagging from any of them.

at $89 it's probably easier and about the same price as replacing the shelves with new wood.

cheapest option is going to be whatever’s free. if you don’t have access to leftover/free shite I would used treated 5/4 x 6” deck boards or treated 1x6’s. But before I bought anything new I would definitely try to scrounge up something free.
Or like you said go to uline.com and buy replacement shelf boards

Might be able to call a local steel supplier and see how much expanded steel is. They're sold in 4x8 sheets. I'm not entirely sure what the supports on your frame look like but maybe an option to explore.

5/8ply is like $23. One sheet would do 4 shelves. Cut so the ply's grain is perpendicular to the length of the shelf. That will hold anything reasonable you put on it and will not sag unacceptably.
Only thing cheaper is going to be something free.

Just a caution about wire shelving. I bought some wire food storage racks at a bankruptcy sale 30 years ago. I thought that they had held up well until I emptied one recently. A third of the bottom shelf had rusted into dust! House washing chemicals in plastic bottles had been stored there.

the outer ply's are the workhorses of a piece of plywood.

30 years seems like a great deal.

i ended up buying a sheet of ply. and another shelve from the 89 link...

I would just get plywood. I have the ones with the wire shelves and if you store any kind of aerosol can or small bottle they don't stay standing up. I'm fixing to either go buy a bunch of 1x's or some plywood to redo all mine. Also if you have a bin with any protrusions on the bottom they don't slide on the wire very well.
