Perforated sheet plates
Oblong hole

Oblong hole perforation or so-called oblong perforation is produced on different types of materials: aluminum, cold and hot rolled as well as galvanized sheets, chrome, copper, and brass. Minimal oblong hole perforation primarily depends on the very material thickness within the scope of 3 x 20, whereas there is no limitation as for maximum hole size.
