Wedge Wire


Wedge wire screens, panels and cylinders

As a product with numerous specialized applications, we can supply or produce wedge wire products in SS430, SS302, SS304, SS304L, SS316, SS316L materials. These may also be called Johnson screens after the inventor (1904 by Edward E. Johnson who invented the world’s first continuous slot wire wrapped well screen). These are available from 0.01mm (10 Micron) up to 15mm (1500 micron) and with with flanges, end rings or BSP threads. We produce wedge wire products according to specification or drawings.

Generally, wedge wire materials in stock are 430, 304 and 316 stainless steel.

We require as much information as possible for manufacture quotes.

We make Johnson wedge wire screens to 170mm OD in South Africa and smaller diameters with specialist manufacturing associates.

Rod profiles

The supporting rods for the wedge wire need to be selected based on how heavy-duty the application is.

See the above screen cylinder and how it differs from below. The above is generally for a flow from inside to outside, while the below Johnson screen is for the more typical flow from outside to inside.


Due to the many possible wire configurations, the initial specification need to be quite clear.


Mining, as profile wire screens used in mining, recycling and mineral processing

Wedge wire mineral processing and recycling screens have over the years  become synonymous throughout the mineral processing, recycling and  aggregate industries worldwide, being recognised for its incomparable  screening properties for high volume separation and classification, with the ability to cope amongst abrasive materials and heavy duty  applications.

Sieve Bends

You can use a stainless steel sieve screen in mineral  processing plants for coal, potash, taconite, sand, gravel etc..


Wedge wire screens are used in the agricultural industry. Among  these industrial profile screens are sieve bends, flat panels and  cylinders used in screw presses.

  • Primary agricultural uses for wedge wire screens:
    Feed screening
  • Feed recovery
  • Manure separation

Wedge Wire Screens for Waste Water and water treatment


Primary wastewater uses for wedge wire screens:

  • Solids removal from process wastewater
  • Process wastewater/sewage treatment
  • Water diversion, keep trash out of rivers, streams, sewers, fountains, etc.
  • Fruit and vegetable wastewater processing

Food Processing and beverage applications

Our wedge wire screens are used in various food processing applications as well as for the de-watering of waste  water in meat, poultry and vegetable processing industries.

Chemical Petrochemical Pharmaceutical Applications

Wedge wire is used for the manufacture of paints, resins, inks, dyes, drugs, chemicals and petrochemicals

Industrial applications

Wedge Wire materials are used throughout the paper/pulp, glass, plastics/rubber recycling,  packaging and agricultural industries.
