Johnson screens consist of V-shape profile wire and the longitudinal support rods.
Material: carbon steel and stainless steel (**2,**4,**4L,**6,**6L etc).
Each intersecting point of these wires is fusion welded. So it has sturdy constriction and good mechanical property. The V-shape section plane can avoid blockage, and make sure of the unimpeded water. Providing more open area, these non-plugging well screens have a tight slot tolerance, effective sand control and a lower entrance velocity. so it can filter sand better.
 We can produce length up to *0’ (6.**6m),Meanwhile, the slot can change according to the real condition of the earth.
