Steel honeycomb ventilation panels have higher physical strength than aluminum honeycomb ventilation panels, and are generally used in military applications that require high levels of EMI. The standard honeycomb has an aperture of 3.2mm and a depth of 12.7mm. The surface layer can be plated with tin, nickel, cadmium, etc. for environmental protection. If the equipment works in the harsh smoky environment in the field, choose a brass honeycomb ventilation plate.
