Window and door screen corners

Hi. I have large screen frames I had made but they used plastic corners to connect the aluminum frame side and top and bottom pieces. The frames are so large ( about 55 inches) they are too flexible and the corners keep breaking. Are there any 90 degree metal corners available for this purpose?

It's a shame. I'm afraid they don't make aluminium 90 degree corner keys, just internal ones like our 95-012M. I'm sorry we can't be more helpful.
