I am using 4 posts with 4x6, rafters are 2x6 every 16'', ' beam double 2x8 bolted to post one on each side, is the beam big enough? It will have a small slope and covered with fiber fiberglass panels.
12' x24' patio 2x6 rafters beams are (2) 2x8 bolted on both sides of 4x6 posts

It's a porch, not a patio...I'm just saying. I don't know your location nor its loads, but around me the typical 1.5-times the lumber's dimension applies. 2x8's (minimum or "Code") would be the rafters for 12' and ANYTHING from 2x8's to 2x12's (what I'd use and suggest) would be the beam, but STILL require (in most cases) a post in the middle of a 24' span...think tie-down too.
