galvanized steel roofing for raised beds

4thebeautyoftheearthJanuary 12, 2013

Hi! I have seen pictures of raised beds made from steel roofing and my (very handy) husband and I are considering constructing similar beds for our garden. Our only concern is whether the metal would raise the temperature of the beds siginificantly. Has anyone had experience with these types of beds? Any words of wisdom? Here is a link to a picture of the kind of bed I am referring to:

I will throw in my $.02 worth because I have been considering the same. All sheet metals are not the same. I used some cheap galv. from Ace hardware for a ground contact application and it did not last long (I am in a wet area). I am using a better grade of steel now for my roof and plan on finding a project to use up my leftovers, if any. The material I am using now is Galvalume which seems to resist rust better.(also reflects heat better) It is also 36" wide while the other was 24" wide. Both galvanized and galvalume will react with the copper in the treated wood. If I do go this route I will try to protect the metal with some type of coating, which may be paint, building felt or plastic, I have used driveway sealer, but the best thing I can say about driveway sealer is that it is cheap.

To make long cuts like is shown on the link, your best bet is a friction disc. They come as an abrasive disc and a diamond coated disc, which will cost between 8 and 20 dollars. (all of these cuts can be made with metal snips if your hands are young enough to use them) A cutting torch would be nice, but I dont have one. I think you will need to shield the edges because the metal in so thin that it would be easy to cut yourself on. You will also need special nails or screws to work on this type of project.

I like the idea of using the composite board, but I understand it is very costly.
