| Flat Wedge wire screen | Perforated plate |
| Wide range of slot sizes and high open areas. | Limited by the mechanical strength of the perforated plate, the hole distance cannot be too small, resulting in the low opening rate of the perforated plate. |
| Has very good smooth filtering surface and high flatness. | During the punching process, the perforated plate is subjected to repeated pressure, resulting in the poor flatness of the perforated plate and affects the screening effect. |
| Welding at each intersection makes it can withstand high pressures and heavy loads, leading to excellent wear resistance and long service life. | Due to the limitation of punching strength, the steel plate cannot be too thick, resulting in poor wear resistance and short service life. |
