Different zone but I had untreated (because of growing vegies) hardwood that finally rotted. It was time to replace so I went with metal beds. They were easy to install and have a cross brace to support the sides.
https://www.northerntool.com/s... I did catch them on sale off season and free shipping.
Due to space I chose 3 x 6 size but other sizes are available. I have gradually replaced 6 of the wood sided beds and hope to do the 7th one this fall.
I hadn't realized how many slugs/snails the wood beds were providing shelter for.
Even in this climate, I don't find the metal sides to be too hot. It might warm the soil earlier in springtime but I suspect the reflective side keeps the soil cooler.
