Requesting info on kit firewall

[John Rheney]

I'm plans building, but want to assemble my firewall as the kit firewall is. It appears that the flanges are shrinked angles riveted onto the firewall material. My firewall proper is stainless and I want to know if the kit flanges are stainless or aluminum. In pictures I've tried to examine the flanges appear to be .032 or .050 aluminum but it is hard to tell from a picture. Are the rivets aluminum or stainless? Any information would be greatly appreciated!

Best,
John

The angle that is stretched/shrunk around the firewall is cut offs of the 5052H32 in .050. The rivets are AN470 normal AL rivets. Mark

Thanks Mark. That is exactly what I was looking for.

Happy New Year to everyone,
