Dana Hospital produces a wide range of perforated metal sheets in various materials like steel, stainless steel, and galvanized steel. The sheets are available in basic forms like sheet, panel, plate, screen, coil, and tube. Popular perforation patterns include round, square, staggered, and decorative. Round holes are very strong and used in walls, ceilings, sunshades, and air conditioning grilles. Square holes are used for displays and machine guards. Staggered perforations best sort objects and are made to customer requirements.
