Common Terms Used in Metal Roofing

  • Gauge
    • The term gauge indicates the standard thickness of sheet metal for a specific material
    • As the gauge number increases, the material thickness decreases
  • Coating
    • Finished Material Used on the Surface of the Roofing Metal.

Common Materials:

  • 26 & 24 Gauge Grade 50 Structural Steel Galvalume
    • Galvalume (Aluminum & Zinc coated Steel)
    • Galvalume steel is made up of two types of protective mechanisms:
      • Zinc – Gives a sacrificial galvanic protection from corrosion
      • Aluminum- Forms an oxide protective layer that serves as barrier protection
    • Used in Residential and Light Commercial roofing projects
    • Most common material used in metal roofing
    • Offers superior corrosion resistance over galvanized at a comparable price
  • 29 Gauge, G90 Galvanized Steel/Galvalume Steel
    • Zinc – Gives a sacrificial galvanic protection from corrosion
    • Coating weight = Amount of Zinc on the top & bottom of the steel per square foot
    • So, G90 Galvanized steel has 0.9 ounces of zinc per square foot
    • G60 Galvanized steel has 0.6 ounces of zinc per square foot
  • 29 Gauge, Galvalume Steel
    • Galvalume (Aluminum & Zinc coated Steel)
