The slots are punched in a flat sheet and at the same time the sheet is rolled into a tube and welded. Slots are arranged in staggered arrangement to reduce negative effect on the screen’s strength.

The slot of bridge screen is like a gravel pack retainer allowing the odd of blocking is very low. The prerequisite of bridge screen is the right gravel pack design.
