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 is 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.

Bridge slot screens have openings arranged in rows and are staggered to reduce the negative effect on the screen’s strength. Typically the slots are punched im a flat sheet that is subsequently rolled into a tube and welded. Regaarded as the best choice of well tube filter,they are widely applied in a variety of fields in the advantages of bridge slot screens,when compared with other kinds of screens,can be listed as follows:

1 High strength through resistance to twisting,compressive,andtensile forces.

2 A smoth bore that does not impede the passage of probes,tools,etc.

3 The special structure of the slot makes it difficult for particles to get stuck in the slot, thus bettering its discharge capacity.

4 The special bridge slot of screens help impoving their mechnic strength.

5 Application of Antivorrosive coasting will prolong the span life of wels.

6 Slots and the diameter of bridge owing to various connecting methods between screens.

7 Convenient to oerate owing to various connecting methods between screens.

8 Lighter in weight and lower in price.
