Bridge SLot Screen : Characteristics: It’s a type of well screen with vertical slots that are formed by protruding "bridges”that are pushed outward from the well casing. The sand and gravel can not easily block the slot because of the special bridge design. It has great mechanical strength and water entering capacity. Meanwhile, it use steel punching technology and rolled in many ways, so it is light, cheap and easily operating. We use CNC to punch, so the slot can change as your requirements. In order to give customers more convenience, we can offer any diameter screens. We also offer galvanized ones to prolong the operational life.
