What is a wedge wire screen?

A wedge wire screen is a metal filter product with high mechanical strength and a self-supporting structure. 
It is made of two parts: a V-shaped profile wire and T-shaped (triangular) support rod, which is welded through the ring fusion welding process. The profile wire is the filtering surface, and the supporting rod plays a supporting role.
Compared with other metal filter cores: Firm structure, stable filtration accuracy, not blocked, high opening area.


1. 10-micron maximum filtration accuracy.
2. Patented surface treatment technology to improve the product’s corrosion resistance.
3. The wedge wire (profile wire) with a tilt angle can be customized according to the customer’s requirements.

Full Welded Wedge Wire Screen Technology

wedge wire screen manufacturers - Bluslot filter

Wedge Wire Screen Machine

1.  V wire structure, the small contact area between impurities and screen.
     So it has the property of not blocking and easy to clean.
2.  Adopt the most advanced ring fusion welding technology on the market at present.
     Compared with other kinds of metal filtration products, its strength is greater.

3.  Stable filtering accuracy
     As for the metal mesh filter, with the use time increases, the filter layer will be seriously worn, the hole diameter will change, and filtering accuracy will change greatly.
     The wedge filter element does not have this problem.

4.  Pressure drop.
     Low-pressure loss, energy saving.
5.  Large opening area.
     Continuous slotting structure, therefore, compared with other kinds of metal filter elements, its opening area is larger.
6. High capacity & flow rate.

Filtering accuracy
In 2016, our technical team independently developed new production equipment after years of production experience:
Minimum filtration accuracy up to 10 microns.

This is a huge technological breakthrough, which improves the competitiveness of our products. 
That is to say, our products can be applied to projects requiring more precise filtering accuracy.

Advanced welding technology
We use the most advanced fusion welding technology at present, and the welding position between the profile wire (vee wire) and the support rod is stronger.

Our equipment can produce products with a maximum diameter of 880mm(Positive volume), reverse volume type exceeds 1800mm.

Surface treatment
Generally, the finished product will be pickled, so that the product will appear bright.
With China’s emphasis on environmental protection, this treatment process has been banned. We independently developed a new treatment process to physically treat the product surface, which not only has a smooth appearance but also greatly improves the service life of the product.

Wedge Wire Filter

Strong mechanical strength
Freestanding construction
Absolute precision filtering
Not easy to block, easy to clean and other characteristics make the wedge wire mesh the best metal filter material.
Construction: Wedge wire screen is welded by V-shaped wire and supporting bar, there is a proper row spacing between the parallel arranged wedge wires, which determines the filtering area.
We take strong production capacity as a guarantee, can produce a cylinder filter element (diameter 21mm-1850mm, length 6m).

Our strengths:

1. High roundness
2. Error control
3. Up to 10-micron filtration accuracy
4. Strong technical team, providing professional customized services
5. Low cost (price)
6. Welding process. Different from the traditional resistance welding, we adopt the most advanced circular fusion welding technology to make the wedge profile wire welding more solid, not easy to take off and deform.

Wedge wire screen open area calculation

The opening area is a very important parameter, it’s also the easiest problem for customers to purchase products.
For example, the roller screen used in distillery’s distiller’s grains dehydration equipment. The efficiency of the equipment can only be determined by specifying the opening area of the required screen, only when the opening area of the screen is determined, can the appropriate v-wire size and the appropriate gap size be selected.
The calculation formula of the opening area is not complicated:
Open area rate = Slot size / (slot size + width of V-wire).

It should be noted that the strength of the wire should not be neglected because of the pursuit of a large opening area.
Under the fixed size, the opening area can only be increased by reducing the width of the wire, but this also reduces the strength of the product, so the area of the opening should be increased as much as possible on the basis of ensuring the strength.
