As a result of the production process, whole perforated plates always come with one unperforated border (solid metal) which is between 3 and 20 mm wide.
Perforated plates are plates that have a large number of identically sized holes which have the same geometrical form and which are placed in evenly staggered patterns, diagonally staggered patterns or straight rows (square pitch). Many different types of material are hole punched: primarily steel and aluminium but brass, copper, tin, nickel or titanium are also turned into perforated plates; plastic, cardboard or wood fibreboard can also be found running under the perforated plate manufacturer̻s hole punch press.
Applications: Sieves, presses, dryers and filters are the typical uses for perforated plates; speaker panels and washing machines are examples of their everyday use.
Perforated plates are, however, being used more and more in the realms of decoration, design and other creative endeavours. Some examples of use include such things as facing for construction pieces, in furniture construction and lampshade production all the way to everyday utility items. Aluminium and steel plates with fine perforations are often found being used in architectural model making but can also be used for jewellery and handicrafts work as well.
