Q: Are the edges of these brackets smooth?

The quality of these brackets exceeded my expectations, sturdy construction, smooth and burr-free, and the included screws are of excellent quality. Perfect fit to my cabinet corner braces. very easy to install. Would recommend, and buy again.

Q: I'm afraid to use the screws that come with these brackets. What size did you use to replace them - #6, #7, #8?

The screws were just the right depth and had no problems going into the holes I center-punched. The head of the screw sinks flush with the surface of the L-bracket so you end up with a flat surface area. Overall a good shopping experience. Would come back again if needed.

Q: How many of these would I need to brace the corners of a bed platform?

I have no idea without seeing the platform. I will say that I made a table with 4x4" legs (4 legs) and put two braces per side of the 4x4s. That's 8 braces per leg. I wanted the screws to bite in deeper, so I bought longer screws to anchor the braces. I'm able to sit on it and bounce around without the table shaking at all.

Q: Can these be used on an aluminum extustion greenhouse?

I'm sure the bracket would satisfy your needs, however I'm not a fastening expert, but your might consider replacing the fastening hardware / or verifying the provided screws will properly secure it to your aluminum structure.
