Wedge Wire ScreenIs made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. the wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.
 
Advantages
1. Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells. 
2. Low cost operation Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level's down, thus to save energy consumption.
3. Reduce the abrasion of the pump 
under the same condition, high open area can make the speed of groundwater's entering into the screen much slower than any other filtration apparatus, which will avoid sand's entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of wells 
Comparatively, groundwater's entering into screen with higher open area is much easier than the entering into lower open area screen. the slow water flow shall extend the life span of wells.
