 General Information on Perforated Stainless Steel Sheet Metal

Because of its duarability and weather resistace 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 accoustic diffuser, speaker grilles, basket strainers, vibrating strainers for solids, waste paper baskets, street furniture, radiator covers.

General Information on common Grades of Stainless Steel 

Grade 304 stainless steel, formerly known as 18/8 stainless, is the most widely used stainless. It has excellant 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 panelling and moderately corrosive environments, (e.g. vegetables, fruits, drinks, dry food etc)
