Bridge slot screens have openings arranged in rows and are staggered to reduce the
negative effect on the screens strength..Typically the slots are punched in
a flat sheet is subsequently rolled into a tube and welded.Its advantages:

1) High strength through resistance to twisting, compressive, and tensile forces
2) A smooth bore that does not impede the passage of probes, tools, ect.
