Trislot® welded screens are directly produced as a flat screen. This avoids the chance of stress corrosion and the weakening of the welds, which does occur with opening and flattening slottubes (this is the normal way to manufacture flat screens).
For special applications welded screens can be made out of slottube. The
Tri slot® welded screens are available in very light constructions (115/Q25) as well as more robust forms (S0S/50x3) and can be provided with the necessary frame and/or reinforcements.
