Woven Wire Mesh by STAR SCREENS has been involved in the market since 1905. All material are woven from wire as thick as 1,6 diameter down to those finer than a human hair of 0,016 diameter.

Steel: Spring Steel, Bright and Galvanised Mild Steels.

Stainless Steel: Chromium Steel, Nickel, Chromium Molybdenum Steel, Heat Resisting Steel.
Non-Ferrous Metal: Aluminium; Nickel, MONEL-Metal, Phosphor Bronze, Brass, Copper.

Special Materials: Titanium, Hastelloy and many others.

The more popular wire and woven wire meshes are kept in stock for use whilst the more exotic would be ordered and manufactured for specific customer requirements. State of the art equipment and a team of qualified experts manufacture wire screens, wire mesh and wire mesh products suitable for all applications.

Standard rolls, roll sections, sheets with fixed dimensions, hooked screens, strips, discs, fabricated parts, filter candles, discs, cones, plates, round sieves, extruder screens and many others are manufactured by the following process: Cutting, cuttting into lengths, bending, stretching, cleaning, plasma welding, welding, soldering, punching, stamping, compressing, forming and many others. Whether in large quantities or small we will supply you with what you require.

Materials for Woven Wire Cloth

STEEL. Plain, low carbon steel is widely used material. However it shows a tendency to corrode. Steel wire is also manufactured in bright galvanised finish.

SPRING STEEL. This is a steel with high carbon content and manganese elements. It is extremely resistant to abrasion and vibration and - at the same time - it is elastic. Therefore it is especially suitable for tensioned steel screens.

STAINLESS STEEL. Stainless steel is the most widely used material for woven wire mesh, covering most applications. It is produced in different kinds of alloys. The most common steel contain ca. 18% chromium and 8% nickel (AISI 304) for a higher degree of corrosion resistance a special alloy with molybdenum is recommended (AISI 316). If woven wire cloth made from stainless steel is welded, the alloy should contain very low carbon or the steels should be stabilised with titanium or niob.

HEAT RESISTING STEEL. These steels are resistant to temperatures of above 600° to 1 200°C in air and in specific gases. However, when sulphine conditions, water, vapour or ashes are added together with heat we recommend special materials such as Incoloy DS.

COPPER AND COPPER BASED ALLOYS. Copper is a soft metal with good conducting properties for heat and electricity. Brass is a copper-zinc alloy particularly suitable for sieving and filtration purposes. When there is ammonia in the air, brass is subject to corrosion. The higher the zinc content, the faster the brass corrodes. Phosphor Bronze, a copper-tin alloy is largely wear and tear resistant.

NICKEL AND NICKEL BASED ALLOYS. Nickel is resistant to a number of acid and alkaline chemical corroding solutions. The material is suitable for welding and about as hard as steel. Nickel based alloys such as Inconel, Incoloy, Hastelloy and others are not always weavable, so a special enquiry is advisable. MONEL-Metal consists of 2/3 of nickel, about 1/3 of copper, and traces of iron, manganese, silicium and carbon. It is very similar to nickel, easy to weave and resistant to atmospheric corrosion, seawater and most acids and alkalines.

MICRO-PLASMA SEAMS

Star Screens' unique Micro-Plasma seams are highly successful in applications where a join between two pieces of wire cloth is necessary but the marking of product, associated with traditional seams, is unacceptable. The construction of wide wire cloth pieces by joining smaller pieces, the seaming of continuous conveyor bands and cylindrical mould covers are examples of applications that benefit from this process.

The Micro-Plasma seam is 100% stainless steel of the type used within the parent wire-cloth. This offers the following benefits:

Aperture Size: is maintained at the seam, critical in applications where air flow and drainage is important.

Product Marking is virtually eliminated because there is no physical interruption at the seam.

Corrosion Resistance increases because the Micro-Plasma joint is 100% stainless steel with no filler or brazing materials used.

Extended Life can be anticipated compared to brazed seams due to the significant improvement in tensile strength at the seam.

Micro-Plasma Seaming of wire cloth is possible with round, twist and flat wires.

DIAGONAL COVERS

Due to their superior strength over straight seamed covers, our diagonally seamed cylindrical mould covers are used at the wet end forming process in the paper, board and fibre cement industries. They can also be found within the fibre preparation plant of a paper or board mill.

Diagonal covers offer superior tautness by shrinking onto the cylinder, effected by axial tensioning of the cover. Some of the materials and weave patters available are shown in the table. Seams can be traditionally brazed in the case of bronze, or Micro-Plasma seamed for stainless steel.

Depending on the construction of the cylinder mould the diagonal covers can be used on their own or in conjunction with a coarser undercover for additional support. Both can be tailored to suit the mould diameter and face width in question.

Pre-seamed Diagonal Covers eliminate the need to seam covers on the site and so reduce plant down time and associated costs

Delivery

Roll lenghts: A standard roll is 25 or 30,5 m long, and half rolls are 12,5 and 15m long. The length of rolls may be + or - 10%. The delivered length is the one invoiced.

Partial lengths: A wire clothroll may consist of a maximum of three roll pieces. The minimum length of a roll piece is 2,5 m.

Cloth width: For rolls and roll pieces, the width of the cloth shall not be less than the nominal width, but may be up to 2% in excess. The overall width shall be measured.

Strips and cut-to-size-pieces: For strips, the width shall be specified. With orders of quantities of less than a standard roll, the length of individual strips may be reduced accordingly. For cut-to-size pieces, the sides, lengths, angles and radii shall be specified.

Requirements for Ordering Woven Wire Mesh

	Quantity: number of pieces or rolls.
	Dimensions: length, width and / or overhook dimensions.
	Material type.
	Aperture width: "w".
