Galvanized slotted screens are a different version of traditional screens as they can be manufactured with quiet small diameters, but their really innovative feature is that slots are directly punched on the pipe with a special plant engineered by our technical department staff. 
Slots width is 3,2 mm (gravel punching), 5 or 8 mm (net punching) and holes can be made on the entire screen surface or only on part of it.
This type of screen is usually used for artesian wells or drainage in particular working conditions.
