How do you plan to attach the screen to the PVC pipe?
How big is the enclosure?
They do make screen window replacement kits at most hardware stores and even via a few websites. These include the frame joints and screen to make a square window. This is probally the easiest way to approach a screen enclosure. After you build the sides and top simple use machine screws to attach the individula window pieces.
Different sizes can be combined to make a door. You can also use rivets.
Quite a number of people have built enclosures in this fashion, perhaps one will post some pics.
Good Luck
