Firstly, pardon my ignorance about this topic because I am an electronics engineer.
I designed a 3 mm thick mounting bracket for one of my products. For this, I need to cut a galvanized metal sheet and bend it 90 degrees.
Maybe I am being over cautious, but (per my reasoning) since the galvanized coating is only in the outer section of sheet metal, the 3 mm wide edges will be uncoated, therefore susceptible to corrosion.
Also the 90 degree bent part will be stretched, so coating thickness will be reduced.
Are these effects real? Do they make any practical difference?
