Metal Roofing Type And Gauge

Each number represents a range of inches 0 0179 to 0 0217 for example so two roofs may have the same gauge but slightly different thicknesses.

Metal roofing type and gauge.

For instance stainless steel will have a difference in inches than carbon steel. Most homes in residential areas use 29 gauge metal panels. Making trim from grade 80 however will cause tiny cracks in the metal exposing it to rain and eventually rust. When it comes to 26 vs.

Manufacturers express the thickness of metal panels as their gauge with 22 gauge being the thickest and 29 gauge the thinnest of traditionally sold metal roof and wall panels. The weight of 29 gauge metal roofing may differ though depending on the type of metal that you choose. This combination of thickness and hardness is great for metal panels that require dent resistance. Any difference is minimal in actual thickness but may have an effect on how sturdy the metal is.

29 26 gauge is the thicker metal. Referring to metal thickness by gauge is an old process that i believe is antiquated and should be eliminated. Each gauge represents a nominal decimal range. Metal roof panels are measured by gauge and are usually between 22 and 29.

Other common roofing metals such as aluminum and copper have gone on to refer to metal thickness in decimal form representing exactly how thick the metal is in inches. Metal roofing is produced from different hardness grades. While 26 gauge and 24 gauge are generally the standard for most commercial and residential installations some choose to work with 29 gauge because it is more affordable. Grade 80 is a hard steel used to produce metal panels of 26 or 29 gauges.
