Bridge hole perforated metal is a special perforation manufactured with exacting precision. The combination of heavy sheet thickness and very fine openings provides great resistance for filtering and ventilation. This kind of perforated metal is often used for water drainage shafts and in chemical processing.

The open area of bridge hole perfotaed metal is variable and depends on the depth of embossing. An embossed depth of 1.5 mm (suitable for rape seed) provides an open area of 7.4 % for ventilation. Another example are sheets with an embossed depth of 3.0 mm giving an open area of 18.2%.
