Wedge Wire Screen

Wedge wire screen also known as Johnson Screen or Profile Screen, is a widely using screen for filtration and separation in liquid, gas, mining, food, water wasting, and so on.

Wedge Wire Screen Advantages:
1. Hightop material imported from France and Taiwan.
2. Wedge Wire Screen has a continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone (the aquifer) 
3. A uniform and efficient well development due to the continuous slot opening.
4. A "V" shaped profile wire which avoids clogging and ensures an uninterrupted flow.

Product Forms
Wedge wire screen is available in a wide variety of shapes and sizes. From two basic forms, slot tubes and flat screens, almost all shapes and sizes can be developed to fit customers´ requirements. Some of our most popular product forms are given below.

Wedge Wire Slot tubes
Slot tubes are welded structures with the support profiles being rods in the axial direction of the tube and surface profiles spirally wound around the support profiles.

Slot tubes



Conventional manufacturing method


Hightop manufacturing method (perfect roundness)


They have the unique advantage of very accurate, narrow slot openings and perfect roundness all in one.

Flat wedge wire screens
Flat screens are structures where the surface profiles are welded at each intersection at 90° angles onto support profiles.
