British Standard Sheet Metal Thickness

Specified minimum yield strength 700 n mm2.

British standard sheet metal thickness.

Swg no inches mm. Sheet metal thickness and british standard wire gauge swg. 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.

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. 44 151 526 4777 fax. Tolerances on plate less than 600 mm wide shall be agreed at time of enquiry order. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.

Wide strip and plate sheet made of stainless steel. 44 560 115 7793 email. Continuously hot rolled strip and plate sheet cut from wide strip of non alloy and alloy steels. To reflect manufacturing difficulty the tolerances for alloys 5251 5083 6082 are now wider than this although still a little tighter than in bs1470.

Relevant en standards for metal sheets and plates. There is a normal tolerance and also a special tolerance at some thicknesses and widths. Tolerances are given up to 6 5mm thick rather than finishing below 3 0mm. Nominal width 600mm.

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. Sheet metal thickness and british standard wire gauge swg. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminium is 0 0403 inches thick. Compared with the old british standard tolerances bs en 10259 has the following differences.

Nominal thickness 3mm 250mm. 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. Length and width tolerances these tend to be tighter and are now all on the plus side i e. Unit 4 yakira buildings 83 sefton lane maghull liverpool l31 8bu.
