Threaded End Johnson Type Water Well Screens are manufactured using our unique computerized machinery, developed in-house, and in which a continuous length of profile wire of a triangular section is fusion welded onto support rods.
This 'V' shaped profile wire is wound around the support rods over the full length of the screen thus creating a continuous slot opening.
Metal Well Screens offer many advantages including:
A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone (the aquifer)
A "V" shaped profile wire which avoids clogging and ensures an uninterrupted flow.
A uniform and efficient well development due to the continuous slot opening.
