Wedge Wire Screen Terminologies Data
Here we will provide terminologies data for wedge wire screens.
Profile Wire
Profile wire is rolled from a round wire through a series of rolling and annealing operations.
Profile Wire also known as wedge wire, V-wire, Tri-wire or surface profiles. The wedge shape of Profile Wires provides a large opening for material to flow between the wires.
The profile wire sizes please check the data sheet
Support Rod
Support wire is rolled from a round wire through a series of rolling and annealing operations. It is also known as support profiles, onto which surface profiles are resistance welded. Support rod includes triangle wire, round bar, flat bar and wedge wire.
The support rod sizes please check the data sheet
Slot Size
It means the clear distance between any two adjacent profile wires. Slot size is controlled very accurately as it forms the slot through which the filtrate flows.
The Opening Comparison Chart (below) can be used to convert opening units.

Support Rod Distance
It means the clear distance between any two adjacent support rods.
Filtration from outside to inside
FOTI --(filtration from outside to inside) Working surface outside: The triangular shaped slot performing profiles are welded with their wedge side to the inner crossbars. This is the most frequent design which makes the outside working surface smooth,
Filtration from inside to outside
FITO-- (filtration from inside to outside) Working surface inside: The triangular shaped slot performing profiles are welded with their flat top side to the inner crossbars. In this design the flat working surface on the inside is interrupted by the position of the crossbars
Wedge Wire Screen Open Area
An important parameter of the wedge wire screen is the open area. Open area OA(%) is the relation of the slot surface to the total screen surface. Open area is calculated according to the following formula:
OA = S/(S+W) x 100 (%)
W– width of the working profile wire
S – slot size
Wedge Wire Screen Weight
The design of each Wedge Wire screen is produced by combining one of the various Wedge Wire profiles with one of the many different size and shaped support rods that are available.
The information below is for estimating weight of the wedge wire screens.
Wedge Wire Screen weight = Wedge Wire weight + Support Rod weight
