Gi sheet metal gauge.
The equivalent thicknesses differ for each standard size of the gauge which has been developed based on the weight of the sheet for a given material.
Gauge or gage dimensions are numbers that indicate the thickness of a piece of sheet and a higher number refers to a thinner sheet.
Galvanized gi sheet metal gauge to inch mm thickness.
Converting sheet metal gauge numbers to millimeters is as simple as following the chart below.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Typically the even number gauges are used more frequently.
The gauge number 18 holds no relevance to the actual measurements.
The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness decreases.
This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
