British Standard Sheet Metal Thickness

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

British standard sheet metal thickness.

Tolerances are given up to 6 5mm thick rather than finishing below 3 0mm. 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. Thickness tolerances considerably tighter for alloys 1050a 3103. Non alloy and alloy steels including stainless steels with.

Nominal thickness 3mm 250mm. Compared with the old british standard tolerances bs en 10259 has the following differences. 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. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Continuously hot rolled strip and plate sheet cut from wide strip of non alloy and alloy steels. Swg no inches mm. 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. 44 560 115 7793 email.

44 151 526 4777 fax. Hot rolled steel plates 3 mm thick or above tolerances on dimensions and shape. Tolerances on plate less than 600 mm wide shall be agreed at time of enquiry order. There is a normal tolerance and also a special tolerance at some thicknesses and widths.

Sheet metal thickness and british standard wire gauge swg. Nominal width 600mm. Wide strip and plate sheet made of stainless steel. Specified minimum yield strength 700 n mm2.

Length and width tolerances these tend to be tighter and are now all on the plus side i e. Sheet metal thickness and british standard wire gauge swg. To reflect manufacturing difficulty the tolerances for alloys 5251 5083 6082 are now wider than this although still a little tighter than in bs1470.
