 8" Flat Pan 

The 8" flat pan roof is another one of our products that we have been producing since we originally designed the structural pan roofs in the 1960s. Think of the flat pan roof as a structural standing seam roof system. It's design helps prevent leaks while being structurally sound. Due to its single skin roof system, insulation is very low. Even though it isn't designed to hold the weight of a person, it's strong enough to stand most weather conditions. This is one of our most economical roof systems we offer. If you're looking for a screen room or seasonal usage only room then the flat pan might be the ideal roof for you. It comes in several different gauges of aluminum from .018 to .038 thick to handle most heavy snow loads.


"V" Pan patio covers are a decorative affordable design while offering equal protection. Our V-Pan patio covers use a aluminum extrusion. Providing strength and stability to span great lengths and provide great protection. C-Thru's V Pan patio covers are manufactured with high quality baked enamel aluminum for years of maintenance free enjoyment.
