This is expressed in gauges with a lower number indicating a thicker sheet and a higher number.
Corrugated iron sheet thickness.
Metal tips steel thickness chart the charts that follow illustrates the tolerance variation for galvanized hot rolled and cold rolled steel.
Regular ferrous alloys are the most common due to price and availability.
The tolerance variation is directly related to and dependent on the specified width and thickness of the material to be roll formed.
0 475 mm 28 gauge can be used for shelters when wind speed is lower than 250 km h in a region not subjected to snow.
Common sizes of corrugated material can range from a very thin 30 gauge 0 012 inches 0 30 mm to a relatively thick 6 gauge 0 1943 inches 4 94 mm.
Measuring thickness the other important measurement for corrugated roof sheets is thickness.
The most common materials for corrugated iron are ferrous alloys e g.
Metal corrugated roofing sheet thickness 0 2 1 0mm.
Gague are used to specify the thickness of a metal sheet.
Stainless steels aluminium and copper.
