To reflect manufacturing difficulty the tolerances for alloys 5251 5083 6082 are now wider than this although still a little tighter than in bs1470.
British standard sheet metal thickness.
Sheet metal thickness and british standard wire gauge swg.
Manufacturers standard gauge for sheet steel is based on an average density of 41 82 lb per square foot per inch thick equivalent to 501 84 pounds per cubic foot 8 038 7 kg m 3.
Wide strip and plate sheet made of stainless steel.
Relevant en standards for metal sheets and plates.
Nominal width 600mm.
Nominal thickness 3mm 250mm.
Swg no inches mm.
Grit blasting prior to galvanizing is usually the most appropriate method and a requirement for a nominal coating thickness of 1000 g m 140 µm has been successfully specified for steel of 6 mm section thickness.
Gauge is defined differently for ferrous iron based and non ferrous metals e g.
Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
Tolerances on plate less than 600 mm wide shall be agreed at time of enquiry order.
Compared with the old british standard tolerances bs en 10259 has the following differences.
Specified minimum yield strength 700 n mm2.
Hot rolled steel plates 3 mm thick or above tolerances on dimensions and shape.
There is a normal tolerance and also a special tolerance at some thicknesses and widths.

Continuously hot rolled strip and plate sheet cut from wide strip of non alloy and alloy steels.
Gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.
