Metal Roofing Gauge Steel

Metal roofing sheets are typically produced from steel aluminium or tin.

Metal roofing gauge steel.

The gauge of a metal roof refers to its thickness and the higher the gauge the thinner the metal. 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. 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. It is done primarily only with steel today.

When it comes to 26 vs. Any difference is minimal in actual thickness but may have an effect on how sturdy the metal is. For this reason the majority of our metal roofing sheets are manufactured from galvanised steel. Each gauge represents a nominal decimal range.

For higher end residential metal roof installations you should aim for at least gauge 26 steel or better yet 24 or 22 gauge smaller number for gauge is better the smaller the number the thicker the panel galvalume steel or aluminum panels finished with kynar 500 paint. While a beautiful new home with a standing seam roof would likely be 24 gauge. Some steel shingles and tiles have a baked on granular coating that adds to their thickness and the mra notes that those products are usually made from 26 gauge steel. 29 26 gauge is the thicker metal.

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. The vast majority of what we sell is either 26 gauge metal roofing or 24 gauge metal roofing. Metal roof panels are measured by gauge and are usually between 22 and 29. For example standard 29 gauge steel roofing made in long panels is about 0 36 millimeters thick and the 26 gauge version is slightly thicker at 0 48 millimeters.

Most homes in residential areas use 29 gauge metal panels. For instance stainless steel will have a difference in inches than carbon steel. Metal roofing is produced from different hardness grades. Making trim from grade 80 however will cause tiny cracks in the metal exposing it to rain and eventually rust.

Grade 80 is a hard steel used to produce metal panels of 26 or 29 gauges. Gauge is the thickness of the metal used for a roof. This combination of thickness and hardness is great for metal panels that require dent resistance. The thickness of copper is different than for steel.

The most common gauges for metal roofing are 29 26 24 and 22 gauge. But due to how well steel handles tough weather it is the preferred materials amongst brands such as britmet and corotile. These numbers refer to the decimal thickness of the steel and they have a range. The weight of 29 gauge metal roofing may differ though depending on the type of metal that you choose.

Most metal roof and metal siding panels on the market are between 20 29 gauge with 20 gauge being the thickest and 29 gauge being the thinnest panels sold. But be wary of basing a decision on roof gauge alone.
