Metal Sheets Ltd are suppliers of Perforated Stainless Steel Sheet Metal, we offer full sheets and a Cut to Size service.

Perforated stainless steel sheets can be used for technical purposes such as strainers, filters and sieves in food processing, brewing and acoustic diffusers as well as interior design and architectural features. Our perforated stainless sheets are in grades 304 and 316 stainless steel as shown in the table below.

Our perforated stainless steel has a hole pattern which is a Staggered “T” so the distance between hole centers is the same in any direction. The term O/A in the table below is the Open Area i.e the free area to allow flow of liquids or gasses.

Note: We now offer circle cutting in perforated sheets up to 1000mm diameter. One off or quantity.

Perforated Stainless Staggered T Pattern

Hole layout is Staggered Tee Pattern (Note the full sheet has a curf of 10mm on length)

Because of its durability and weather resistance many architectural building products are manufactured in perforated stainless steel, even whole building facades or decorative features like sun screens, balustrade infill panels and ventilators.

There are many functional uses for perforated stainless sheet because of its corrosion resistant properties, Filtering and screening is a major application in the food and brewing Industry. Tea strainers even.

Other applications include acoustic diffuser, speaker grilles, basket strainers, vibrating strainers for solids, waste paper baskets, street furniture, radiator covers.

Grade 304 stainless steel, formerly known as 18/8 stainless, is the most widely used stainless. It has excellent corrosion resistance.

Typical catering uses for grade 304 are vats, bowls, pipework, table tops.

Grade 316 stainless steel is more corrosion resistant than 304 and is suitable for marine and coastal applications.

Typical catering uses for grade 316 are components used with more corrosive foods, (e.g. meat/blood, foods with moderate salt content) where frequent cleaning takes place

Grades of stainless steel higher than 316 are available for use in more corrosive environments such as hot brine, salty and slow moving foods.

Grade 430 stainless steel is a lower grade stainless and is suitable indoor uses. It has good corrosion resistance.

Typical catering uses for grade 430 are splash backs, table tops, equipment cladding and paneling and moderately corrosive environments, (e.g. vegetables, fruits, drinks, dry food etc)
