Technical characteristics Besides its basic features (as shape and arrangement of the holes) a perforated product is defined by a number of technical characteristics as listed. The requested range of tolerances will strictly depend on the technical needs of each specific application. Please note that the requested tolerances affect the complexity of the manufacturing processes of the perforated products and therefore their final costs. • Overall length and width of the sheet/coil • Length and width of the perforated areas and unperforated margins • Flatness • Squareness • Surface aspects:...

Perforated material can be supplied in coils of different widths and lengths, as well as in sheets of different sizes. Sheets can be delivered in thicknesses between 0.3 and 25 mm. The available widths of perforated coils go from 55 mm to 1500 mm, with a maximum weight of approx. 8000 kilos. Thicknesses range from 0.3 to 3.0 mm. Guide to raw materials Terms under the European norm and the most used terms in DK, SE and DE.

For a detailed list of available patterns refer to www.rmig.com Conical holes On this page some of the patterns are shown for which tools are available. Where very small holes are required, relative to the sheet thickness, the solution may be a Perfocon sheet as described on page 20. For normal perforation, the maximum thickness of mild steel sheets may exceed the hole diameter by approximately 25%. Therefore, for normal perforation, 2 mm holes can be perforated in sheets up to 2.5 mm thickness. For special perforation, the sheet thickness may exceed the hole diameter considerably. For...
