Higher Gauge Sheet Metal

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.

Higher gauge sheet metal. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. We service the greater columbus area including powell dublin hillard lincoln village and south columbus.

Each gauge represents a nominal decimal range. You can find a gauge. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness. As the gauge number increases the material thickness decreases.

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. The problem with metal roofing gauge is that there is a wide range of tolerances. We carry all metal shapes. For other materials such as aluminum and brass the thicknesses will be different.

If the gauge thickness value is higher that indicates the thinner sheet. This system is used for both wire and flat sheet plate of metal not just stainless steel though the actual decimal thickness of a given gauge will vary between materials more specifically. This is known as the manufacturers standard gage for sheet steel. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

For example one company might sell a product as being 24 gauge but in reality the thickness of the metal could vary from 0 018 to 0 0335 based upon exactly how that company looks at things and how big of a tolerance they allow for. Thus a higher number gauge means a thinner material. Gauge numbers run from 3ga 0 2391 thick up to or should that be down to 38ga 0 0060 thick typically though most sheet metal folks switch over to talking about plate for thicknesses greater than 10ga or 0 1345. Bar tube sheet plate structural rare exotic metals and more.

That way if we suggest something like switching from 14 to 16ga to tighten a bend radius or save weight you ll know what we mean. You should also know about gauge when discussing sheet metal with your friendly indiana based metal fabricator. If the gauge thickness value is higher that indicates the thinner sheet.
