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.
Corrugated iron sheet thickness.
Measuring thickness the other important measurement for corrugated roof sheets is thickness.
Gague are used to specify the thickness of a metal sheet.
This is expressed in gauges with a lower number indicating a thicker sheet and a higher number.
The tolerance variation is directly related to and dependent on the specified width and thickness of the material to be roll formed.
0 4 mm 30 gauge can be used for shelters when wind speed is lower than 200 km h in a region not subjected to snow.
Stainless steels aluminium and copper.
Regular ferrous alloys are the most common due to price and availability.
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.
0 551 mm 26 gauge for permanent shelters.
The most common materials for corrugated iron are ferrous alloys e g.
