Perforation Types / Product examples and Applications
| Round Holes | Type R | Quality | Product Examples | Main Applications |
 |  | The staggered arrangement of the holes provides optimum mechanical strength combined with a personalised design. For sorting and sifting industries, the staggered arrangement aids efficiency. | Filter elements, strainer Spacers for autoclaves Drying trays, speakers Lighting, Furnishings, Displays… | Filtration, separation, ventilation,bracketing, screening, isolation,air conditioning, absorption, sound insulation, decoration, drying, protection, shredding, sorting, grading, urban development |
| Materials The most popular material is stainless steel to DIN 1.4301 (AISI 304) or DIN 1.4401 (AISI 316); selected specifications are also available in chrome steel to DIN 1.4016 (AISI 430). | ||||||||||||||||||||||
Wire Diameter Selecting the wire diameter involves a number of different considerations.The thicker the wire, the stronger and more robust the mesh and the longer the service life.On the other hand, a thicker wire will reduce the open area and therefore reduce screening or sifting performance. Reducing the wire diameter, whilst maintaining the same aperture size, increases the number of apertures within a defined surface area. Both performance and efficiency will increase. |

| Mesh Dimensions Standard widths are 1245mm or 1580mm, but depending on the weaving equipment used slight variances are common. Standard roll length is 30m, individual pieces cut to size are available. | ||||||||||||||||||||||
Mesh Selection The mesh selection, particularly with fine meshes, depends on many process details and The open area is influenced directly or indirectly by the service life of the screen, |
