This patio cover is manufactured by Acrylite, this particular one was powder coated a custom grey color. It is all aluminum framing and dual wall acrylic roofing to let the light shine through. it keeps the rain off, provides shade in the summer, and keeps it cool as well. This is the best patio cover you can buy for durability, low maintenance, and longevity. Note, we don’t normally install a beam along side the house, that was a special request by the customer.
