what gauge steel is metal roofing
The 29, 26, and 24 metal roofing gauge is a measurement of the thickness of the metal, but it's important to remember that the metal increases in thickness as the gauge numbers decrease. Union offers several gauge options for metal roofing. Listed in order from thinnest to thickest, they are Utility, Econ 29, 29, 26, and 24 gauge. It's important to note that 29 gauge metal roofing is the thinnest metal recommended for residential applications. Our heavy duty 24 gauge metal roofing is recommended for those areas with severe weather, high winds, or hail.
