Choose from aluminum, insulated or steel covers. Aluminum
kits are pre-finished, maintenance free and
pleasing. You three choices are “W” pan ( some times
called “V” pan), flat pan style, and insulated. When
viewed from the underside the “W” pan has the shape of “W” shape
visible, the flat pan and insulated resemble a flat ceiling.
The flat pan or insulated would work as a patio room or screen
room cover. The span capability (load carrying ability) of the different
styles is governed by the thickness of the material and the depth
of the pan. The thickness of the aluminum the roof panel is formed
of, or the thickness of foam (in case of the insulated and the density
of the foam), effect how many feet between supports you can span
and meet a given load requirement. Steel cover are usually used
for commercial installations.
Insulated style carport
covers have a greater clear
span and greater load requirements than W or flat pan covers. Insulated
covers are made of two aluminum panels that are laminated to a structural
(usually 3" or 4" thick). These interlocking panels can be walked
on and stop the heat just like an ice chest.
You also end up with a finished ceiling. A fan beam can also be ordered
inside an insulated panel so you will be able to hang a ceiling fan
from your patio cover without adding any additional support.
