π π π π π 5 star review from Frederick: Fully As Advertised
I assembled a 10' diameter raised planter around a very large dead tree trunk using 12" wide corten steel with 1.5"x1.5" support stakes @ 36" o.c.. The result is a very simple, very sturdy and rather prety installation. I am very pleased. One note of distinction: the 23 gage thickness is robust, with both edges folded over for rigidity and ease of handling. This is good stuff.
ps - Be sure to get a pack of their self-drilling screws for joining the sections - good performance and appearance. Pre-drill a starter hole (this corten is tough stuff!).
pps - I rushed through the recommended pre-weathering process: I cleaned (degreased) the sheets thoroughly but only made a few passes with the weathering solution. No matter - it all rusted out to a deep brown very quickly. I suspect one could ignore the pre-weathering altogether and it would eventually develop a consistent rusted appearance on its own (but it looks so much better right away if you do the pre-weathering).
