As a registered iso 9001 2015 company rolled steel products state of the art equipment meets virtually any requirement in panel flat quality leveling precision slitting close tolerance sheet blanking strip quality edge conditioning precision shearing and complete cold reducing capabilities.

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. An aluminum sheet metal thickness refers to the thickness of an aluminium sheets a flat square or rectangle piece of aluminum material with a thickness of between 0 2mm and 500mm a width of 200mm some are even 50mm and above and more and a length of 16m or less. The aluminum sheet metal thickness can be divided into four categories.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Gauge nominal in mm max in mm min in mm 10. 0 1345 3 42 0 1405 3 57 0 1285 3 26 11. Sheet metal guage tolerances.

In most of the world sheet metal thickness is consistently specified in millimeters. General information of aluminum sheet thickness.
