Re: Raised Beds for Your Garden: Framing Materials

My raised beds are galvanized metal roofing. When I reroofed my barn the old roof generated 60 pieces of 3'x12' galvanized steel. I cut these down the middle generating 120 pieces of 1.5'x12' sheets. I buried these 6" deep and supported the sides with wooden steaks spaced at 3' intervals, giving me beds raised 12" above the paths. Judging from performance over 3 years, I estimate they will last 10 years before they rust away. One concern is that the top edge is sharp enough to cut an unprotected hand. I have not suffered any injury, but if you are concerned, the top edge can be capped with a thin strip of lumber.
