Can i expect from equal aluminium angle 90 degrees on the outside? I was so sure that is 90 degree, so even did not check it when was buying it today. Took it home decided to check the squareness it and it is less than 90 degress.. Tried to google it out, and here is what i found: "A 90-degree angle is certainly the most commonplace for aluminium angle stock, but there are products which have less than a 90-degree bend".
So maybe i was lucky to get that with smaller angle or it is common not to have proper 90 degrees angle? I saw someone was using those angles in this forum to bolt together the frame, wondering if there were some issues with that?
