New metal grate on the window

Put a grate on the window. The price of the grating (material, manufacturing, installation) is $100. It's very cheap. The grid is beautiful. But in some places the metal bars are not even. Why is that? Because this grill was made at home by one of my neighbors. That's why the grate is cheap :) But I'm satisfied. I have 5 more windows without grate. I need to put it in there too.
