How to make edges of cut aluminum flashing less sharp?

Question

Hi, we are trying to do a special project using a sheet of cut aluminum flashing attached to the bottom of our gate so the dog can't see out as easily. We made the cuts and are about to spray paint but have found the edges (especially the cut ones) to be very sharp and have both gotten bad paper-like cuts. Any ideas how to protect the exposed edge so no one gets hurt?

My first thought was a report sleave - like the ones i used to put my book reports in.

Answer 1

You need to dull the sharp edges. Try dragging the edge of some leftover flashing down the length of your installation. If that doesn't work try 000 steel wool or doubled up sandpaper (fine) along the sharp edge.

Answer 2

I like the sleeve idea, that may work,if not try making your cuts with a sharp utility knife it will make a much cleaner cut than tin snips.

If it's still too sharp then try taking the edge of your metal and bending it back on to itself, what they call a hem it will also make your pc. of metal more rigid.



Good Luck



Hope This Helps

Fold the edge over, rubbing in on something will most likely just sharpen it. Fold it over by 1/2 inch or so, press or hammer it down tight, then fold it again. Not only wil it not be sharp, but it will be stronger along that edge. One way to fold it over is to clamp the edge between 2 square edged boards and use your hands to bend it to 90 degrees. After that, use the board to flatten it out. Wear gloves. Good luck.
