Using corrugated sheet metal for above ground garden beds

Any negative to this? Looks like it would be a fraction of the cost of treated pine nowadays.

its better to go with the fiberglass corrugated panels they use for green houses so it doesnt rust LINK

That crap is too fragile in my opinion. I don't think it would hold up to the stresses a full bed of garden soil would put on it.
With the price of lumber, I'd opt for cinder blocks. They are 8x8x16 and cost $1.67 each at Home Depot.

if a grown man can walk on it then its not fragile, it may bend and need a little support in the middle but its no different in strength then that thin corrugated metal he was thinking about
we do this for all our raised beds and every 2ft we have a cross brace, you can stand and walk on it with no issues, thats a lot more weight then a few plants and some dirt weight

That metal will make your garden very hot

In my limited research, I read that’s a myth

NOPE they have worked great for me going on 10 years now
google "lasagna gardening" and try to get a sprinkler or drip irrigation on it prior to filling it
I find that the natural decomp that happens with that style is the most effective

and if you want to "beautify" them some, just spray paint whatever color you want

What about a couple rows of those 8' landscape timbers? They're treated, and under $5 each. Used these years ago and ran lag screws through them to hold them together.
I kind of like the ideas of cinder blocks though... may try that next time.
ETA: last time I got some landscape timbers, some had some damage so they knocked the price down 50%. I just got all the damaged ones since I didn't care

The added benefit of using cinder blocks is you can fill the 2 holes in the blocks with garden soil and plant smaller plants like herbs or some flowering plant in them since each hole is about the size of a gallon plant pot.

I had landscape timbers once and they rotted inside 2 years. I am now a cinder block guy and I regret not doing it sooner. I use the holes in the blocks for my herbs and garlic. It seems to be ideal for my garden. I have 2 "boxes" 5'x30' and it's doing great.

This is a great idea. Can use for other things too, like maybe have the kids plant whatever they want in them.
I'm sold on cinder blocks.

cinder blocks
This is what I do. I use Split face blocks. they are textured to look like stone so they are a little better than regular cinder blocks

I have one raised bed I use for root crops that I built out of 2 x 12's and it is 4 ft. x 12 ft. x 1 ft. deep. I used treated wood and it is now going on 10 years old but showing its age with some rot and bowing out in spots.
When I replace it, I will be using cinder blocks and will probably go 2 blocks high.

Haven't done this yet, but planning on a couple raised beds using the concrete fiber "backer boards" as panels. I've used these on another outdoor project and they hold up well and don't seem to be affected by moisture. They're easy to cut, fairly light, inexpensive and strong.
I'd use this instead of corrugated metal.

go price some cedar 2x10 for a couple raised beds... i'll wait

Yep my little girl planted 2 strawberry plants in the holes. She checks them daily

My concern with sheet metal is heat. I have some big metal pales I've tried to grow in and they don't produce like same size plastic planters. I assume its because it's full sun and heat issue. The soil is always warm. Looking at new prices, I think it'd take me $66 in metal + some framing wood to build a 4'x8'.
I have tried cinder block raised gardens in past, and they work, but mine was sloppy and I wasnt a fan. The blocks never really locked in place even filling the holes with soil didn't really make it stable. I'm going on 7 years with one and the herbs in the holes don't produce well, I'm assuming issue with heat as well. Looking at the current concrete block prices, I'd take me $60 to build a 4'x8' again.
I didn't pay it in today's lumber, but I currently use 1"x6"x8' PT, stacked 3 high, with 2x4 PT in the corners. I build 4'x8' raised beds, so each level takes 3 1"x6"x8' which requires 9 1"x6"x8' + 2x4 to stabilize. Right now that would cost $70 to build another 4'x8'. I'm going on my 4th year with them and much more pleased than anything else I've tried.
I love the wood beds most because they are easy to maintain, move, level, customize, add trellis, add hose reel/irrigation, etc.
