With 20 years experience in manufacturing of wire screen products, Gesenza Konke can supply a range of screening products made to customer specification. Our state-of-the-art equipment, highly skilled staff and quality control procedures ensure that our products are of the highest calibre. We offer our products in a wide range of materials and sizes with wire diameters ranging from 0.035mm to as thick as 20mm, we also supply a wide range of 'fine mesh'.

Products supplied:
  • Wire woven mesh and cloth.
  • Crimped wire screens.
  • High capacity and non-binding screens.
  • Custom made screens.
  • Polyurethane screens.
  • Rubber screen panels.
  • Wedge wire panels.
  • Sieve bends.
  • Nosing rubber.
  • Clamping plates.
  • Springs.
Our products are created with state-of-the-art equipment and our highly skilled staff, along with our strict quality control, ensures an excellent, quality product.

Material for wire screens:

Corrosion resistance, abrasion, operating temperature, vibration, and weight are all factors that must be considered when choosing the metal/alloy of which the screen is made. We can supply screens using the following materials:

Steel:
(Plain, low carbon or galvanized). Relatively low cost, high strength metal for general screening applications, but shows a tendency to corrode. Galvanizing improves durabilitfy and corrosion resistance.

Spring steel:
High tensile spring steel with a high carbon content is normally recommended for high speed screening, making it useful for gravel and stone separating in the mining and coal industries.

Stainless steel:
It is the most widely used material in the manufacture of woven wire mesh and cloth. It is produced in different kinds of alloys. The inclusion of chromium and nickel allows steel to become resistant to staining and corrosion. Differing amounts of carbon, chromium and nickel affect the secondary characteristics such as welding and forming. 304 And 316 are two of the most popular grades.

Copper and copper based alloys:
Copper resistant to atmospheric corrosion with good conducting properties for heat but is attacked by oxidizing agents such as nitric acid, chloride, cyanides and ammonia acids, and is suitable for sieving and filtration purposes.

Nickel & nickel based alloys:
Nickel is noted for its corrosion resistance, good electrical conductivity and high heat transfer properties. Wire mesh woven nickel is used in pure food and drug processing - among several other applications - although nickel wire cloth is replaced frequently with stainless steel.

Crimped wire mesh:

Crimped wire is generally used for 10 mesh and coarser. Crimped weaves are produced in two separate operations; first the wires are crimped to suit the selected pattern and mesh count, then the 'crimped' wires are woven together on the loom. Crimped wire screens have very accurate openings and are very lightly woven. The wires have very little movement, resulting in less inter-wire abrasion due to wires rubbing against each other, less metal fatigue and minimum wire fracture. Crimped wire screens are generally preferred when accurate sizing is important and for vibrating screens where tightness is required.

Hooks and edge preparation on vibrating screens:

We fabricate a number of hooks, strips and edge preparation types to meet the requirements of most vibrators that utilize a tension mount for screen panels. Hook strips reinforce the hooks so that they do not straighten under tension, they enable the screen to be stretched drum tight. This prevents the screen from whipping and sagging with less inter-wire abrasion, metal fatigue and wire fracture. The result is a screen with a greatly increased life span.

When ordering screens with hooks or strips:
  • Give the length of the hook.
  • Give the dimensions between hooks either as the measurements from outside to outside (O.S) or from inside to inside (I.S).
