Perforated sheet metal

Formats The standard format for metal sheet is 1000x2000 mm. We have got a wide range of perforation possibilities already available on stock in this standard format. We can otherwise manufacture perforated sheets and coils in any format, from minimum sizes to a maximum width of 2000 mm. Thicknesses We can provide perforated sheets from a minimum thickness to 0,2 mm up to a maximum of 15 mm while those immediately available in stock range from 0,5mm a 10mm. Holes Holes can be ROUND, SQUARE, RHOMBOIDAL , RECTANGULAR, ROUND END SLOTS, FANTASY PATTERNS, specially customized on the basis of the client's moulding. We also supply round DRAWN holes of several diameters. Due to the perforation process, holes are always slightly conical , but taper increases with the increase in the thickness to the plate. The diameter of the hole shall be measured on the entrance side of the punch, not on the exit side. Hole-thickness ratio The bigger the hole diameter is, the cheaper the price is. For example, taking a 1mm thickness sheet, an 8 mm perforation is much simpler and economical if compared to the same sheet with holes of a 1mm diameter. Over the last few years, GATTI PRECORVI SPA has specialised into micro perforation (up to a diameter of 0,3mm against a thickness to 0,3mm).
