Looking for large(metal) rectangular planter boxes

I’m looking for planter boxes similar to these. Preferably in metal but plastic would be ok too.
Does anyone know where to find these?

You can have things like those made at metal shops easy enough and painted.

Where are you located? There are a few large nursery supplies stores around. I know some good ones if you are central/south.

I’m in Taichung. Would love to see where I could find them around here. The nurseries I’ve been to don’t stock them…

Head to Tianwei nurseey district. Its the largest such hub in Taiwan, about an hour south of you. Make a day out of it its pretty big. They have a few decent sized supply shops.

Thanks for the info! I’ll go take a look when I can
