Trislot flat screens are flat filter surfaces that can be manufactured in two different ways.
Welded screens: directly made on the flat welding machine
Flattened slot tube: manufactured by opening and flattening a slot tube with radial external wire
Welded screen
Trislot welded screens are produced directly on a machine by welding surface profiles onto support profiles at each intersection at 90° angles.
Advantages of manufacturing directly on a machine:
Enhanced profile wire flatness: no profile wire waviness between support wires
Avoids the weakening of the welds and the chance of stress corrosion that can result when producing from a slot tube
Accurate distance between support profiles
Possibility of different support wires in one screen
Flexibility to have variable spacing between support wires in one screen
