It provides rigidity and a mounting surface for the roof skin, helping prevent sagging and leaks. Made of galvanized steel for corrosion resistance, this 16-gauge bow measures 4.19 inches wide and 98.63 inches long. It is commonly replaced when damaged from impacts (e.g., low-hanging branches), rust, or overloading to restore the roof’s structural integrity and weather-tightness.
