Building an Outdoor Aviary?

I would like to build an outdoor aviary for my two birds. A Pionus and a Ringneck. I would to make it large enough for them to fly around and can fit lots of toys. Anyone know of any quality supplies? All I can really think of is chain link. Or even like an idea of what you built, if anyone built one

My 6′w x 12′L x 6′H aviary is made of 1″ x 1/2′ double dip galvanized wire. 4′ wx 50′ L. It’s 30 years old and still strong. The pressure treated wood frame has had pieces replaced. You have hook bills so you would want the wood frame on the outside. The chemicals used in pressure treating is a no-no for chewing parrots.
