| Who Are We? |
| Wirecloth Sales & Development Ltd was formed in 1983. We are strategically based in Warrington, Cheshire, in the heart of the wire industry and the ideal distribution point. |
| What Do We Do? | ||||||||||||||||
| Wirecloth Sales & Development Ltd are certified to
I S 0 9002 (BS 5750 Part 2) and as such, all products supplied by us are
Quality Assured'. We can supply a Certificate of Conformity and Chemical
Analysis with all orders, if specified by the customer. We specialise in all forms of wiremesh, e.g. woven wire, knitted wire, welded wire, perforated metals and expanded metal. We can supply these products in most metal alloy, e.g. stainless steel (all grades), monel, incalloy, brass, copper phosphor bronze, galvanised steel etc., and also in plastic, e.g. polypropylene, polyester nylon etc. We also manufacture products from the above material and can cater for one-off jobs, small, medium runs as well as large quantity runs. Products that we can manufacture to customer requirements include:-
We also supply belts of all descriptions, manufactured
to customers' requirements from the above materials. We also offer
a complete refurbishment service. |

Woven Wire Mesh
|
|||
| SQUARE MESH, PLAIN WEAVE Wire cloth with square meshes. Plain weave gives maximum possible accuracy of apertures and is consequently the most widely used type of weave. Smallest aperture 28 mm . |
 |
DUTCH TWILLED WEAVE Also called "light-tight" weave. The weft wires are twill-woven to lie as close as possible. Qualities: maximum degree of accuracy in filtration low flow-rate, high pressure loss. Smooth on both sides.Smallest aperture 3 my. (nominal). |
 |
| SQUARE MESH. TWILLED WEAVE Wire cloth with square meshes having a slight diagonal displace-ment. Mostly fine wire cloth with apertures under 63 micrometers and specifications woven with especially thick wires. Smallest aperture 25 my. |
 |
BROAD MESH TWILLED DUTCH WEAVE
In contrast to the Dutch Twilled Weave, which is light-tight, the weft
wires lie loosely against each other. Qualities: satisfactory degree of accuracy in filtration, high flow rate, moderate pressure loss. Smooth on both sides. Smallest aperture 20 my. |
 |
| REVERSE PLAIN DUTCH WEAVE Has warp wires of relatively thin diameters lying as close as possible to one another, and the weft wires are particularly strong. Qualities: satisfactory degree of accuracy in filtration, high flow-rate, small pressure loss. Uneven surface on both sides. Smallest aperture 14 my. |
 |
SINGLE PLAIN DUTCH WEAVE The weft wires are plain woven to lie as close as possible against each other. Qualities: high degree of accuracy in filtration, high flow-rate, moderate pressure loss. Uneven surface on both sides. Smallest aperture 15 my. |

Typical Specifications
|
|||
| METHOD OF MEASURING MESH "Mesh" means the number of openings per lineal inch measured from centre to centre of wire: thus the illustration shows 3 mesh or 1/3 centres. |  |
APERTURE OR CLEAR MESH "Aperture or clear mesh" means the actual opening between the wires: thus the illustration shows /4 clear mesh or aperture. From centre to centre of wire |
 |
| METALS USED Each mesh can be made in several gauges of wire according to aperture required and almost all metals: plain steel, tinned steel, galvanised steel, steel, galvanised after woven, copper, brass, phospher bronze, stainless steel, monel, nickel, aluminium and its alloys and special metals. |
HOW TO ORDER

| Knitted Wire Mesh | ||||||||
| What is Knitted Wire Mesh? | ||||||||
| Knitted mesh, as its name implies is a metal wire or plastic strand knitted into an interlocking looped mesh structure the same way as stockings, and should not be confused with woven mesh, which is the form of rectangular openings of parallel wires. The knitted mesh has a flexibility not possessed by the woven mesh, due to the loops being able to move relative to each other thereby giving a two-way stretch.This flexibility gives knitted mesh a unique advantage for many industrial uses. | ||||||||
|
Forms of Knitted Mesh
|
||||||||
| Knitted mesh is produced in a long flat double thickness from 0' to 28 seamless width on a cylindrical machine. The output is a continuous stocking of mesh, which is pulled through the knitter by take-up rollers. It can be used directly in this flattened form as an insulation covering or it can be further processed into several other basic forms. Flattened mesh is sometimes run through corrugating rolls to create crimped mesh. In this form the corrugations act like springs for resiliency and give mesh thickness. | ||||||||
|
Materials
|
||||||||
| The usual materials are metals, aluminium, monel, stainless steel, nickel, copper galvanised steel, and plastics, poly-propylene and nylon. | ||||||||
|
Mesh Sizes
|
||||||||
| The most popular meshes are between 3 and 8 openings to the linear inch. Almost any material that can be drawn into a filament smaller than 0.01 2' (0.3 I mm) for metals (plastics from thicker filaments) can be knitted providing that it has been suitably drawn. | ||||||||

Properties of Knitted Mesh
|
||||||||
| Knitted mesh has both a large surface area of wire and a high percentage of free space The open space in a mesh can be controlled from 50 to 98% since it is possible to knit meshes of a wide range of opening sizes regardless of wire diameterThese features become important in uses such as filtration where flow resistance is critical Another feature of knitted mesh is its inherent resiliency Every loop of the knitted structure becomes a small spring when subjected to tensile or compressive stress, and when not distorted too drastically, will immediately resume its original form upon relief. Even when the mesh is compressed into a special shape a high degree of resiliency is retained.This can be controlled by varying sizes of opening, wire diameter and material, crimping and pressure used to create the part. Compressed, layered, calendered and wound mesh units all have the common property of presenting a 'Tortuous Path" to the flow of liquids or gases through them.This is used in filtration, diffusion, distillation and flame arrestors. | ||||||||
