Woven Wire Screens

Screenex was founded in the late 1950’s as expert wire weavers and we are still the foremost supplier of woven wire screens, fine mesh and screen media in the country.

Polyurethane and Rubber modular screen panels have mostly replaced woven wire screens in the mining industry but it is still widely used in various other industries including Quarrying, Agriculture, Food, Architectural and General Industry.

Material Used

Corrosion, abrasion, heat, vibration and weight are important factors to consider when choosing the metal or alloys to use to manufacture a screen

We specialize in screens woven from high carbon, high tensile spring steel, (unsurpassed for durability and long life with heavy abrasive material) and stainless steel which resists heat and corrosion giving longer life and durability.

High Carbon

Vibrating screens exert a great strain on screens and high carbon wire’s high elastic limit and great tensile strength prevent wire fractures even when the wires are worn. Thinner wire, with reduced cost and weight and higher resultant open area, can be used for the same screen strength.

Stainless Steel

Stainless Steel’s advantages

  • High abrasion resistance – longer life
  • Resistance to chemical and atmospheric corrosion
  • Mechanical strength unaffected by high heat
  • Easily cleaned and ideal for food industry

Grades used

  • AISI 304
  • AISI 316
  • AISI 430

Other Metals & Alloys

  • Copper
  • Brass
  • Phosphor Bronze
  • Monel Alloys
  • Aluminium

Aperture Types

Slotted Aperture

A woven wire screen with one single cross wire and where one side of the aperture is different in length from the other, perpendicular dimension.

We can manufacture slotted screens with plain, intermediate or flat top crimping.

Square Apertures

The warp and weft wires form a square aperture. It is available in a variety of weaves and crimps.

Triple Shute

A slotted woven wire screen with 3 cross wires. Available in intermediate and flat top crimp.

Double Shute Slotted

A slotted woven wire screen with 2 cross wires.

Non Blinding Harp

We manufacture both Serpa Harp and Tria Harp screens.

Serpa (Square) Harp
Forming a square aperture diagonally to flow. It gives good cut point accuracy without blinding.

Tria Harp
Additional thicker wires between the normal harp oriented wires creates non blinding effect through differing vibrating frequency and amplitude.

Types of hooks

All the standard hook and turn-ups are available including

  • Standard overhooks
  • Single fold metal turn-ups
  • Double fold metal turn-ups
  • Double folded, double reinforced metal turn-ups
  • C-plates
Types of weave

All standard types of weave are available including

  • Single crimped
  • Single intermediate crimp
  • Double intermediate crimp
  • Lock crimp
  • Plain weave
  • Twill weave
  • Holland weave
Aperture Sizes

Heavy Wire (larger than 0.7mm diameter)

Aperture sizes vary from 2.4mm to 125mm and larger.

Fine Wire aka Fine Mesh ( smaller than 0.7mm diameter)

As small as 200 mesh (or 40 000 holes per square inch or 0.06mm) up to 2 mesh (4 holes per square inch or 11.08mm)

Available wire sizes range from 0.03mm to 12.5mm.
