Specification Selection Guide
   A wire mesh specification is a precise set of dimensional instructions that identifies the component's by name, the wire description provided as dimensional, (wire diameter) the basic type of material with each type having unique chemical and physical characteristics consists of wires arranged in either a square pattern or a rectangular pattern, which are physically held in position by the weave structure, specifically the indentations (crimps) at each intersection of the particular weave style.

Popular Applications
   
  EMI Electromagnetic Iinterference
  Electromagnetic interference is a disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source. The disturbance may obstruct, degrade or reduce the effective performance of the circuit.
   
  RFI/EMI Screen Room Shielding
  A Faraday cage (or shield) is an enclosure formed by a woven wire mesh of conducting material. Such an enclosure blocks out external static electric fields. Faraday cages are named after Michael Faraday, the inventor.

  No See Ums, Small Opening Insect Screen
  Bite prevention is the preferred way of dealing with these pests. Your home or business can be protected with a special screening which is available to exclude these fliesMost biting midges can pass through a 18 x 16 or 16 x 16 mesh insect screen, so a smaller opening  size (higher mesh count) is required to prevent entry.
   
  Termite Barrier Screening System
  Stainless steel woven wire mesh is a safe long term solution for the prevention of Subterranean Termite and  Insect entry.  The screen provides a physical barrier the insects can not fit through, without containing any chemicals or toxic substances.

  Screen Edge Treatments and Hook Strips
  Screens for classifying, sizing, straining, sieving, are typically secured by clamping rails that apply tension across the screening surface.
   
  Screen Specification Selection Tips
  Assistance with selection of woven wire cloth screen specifications.
   
Square Mesh
  Square Mesh is woven in the same Mesh Count (number of wires per linear inch or millimeters) running in both directions. Warp is the length of the roll, Weft is the width across the roll.
  Wire Cloth specifications always refer to the Warp Mesh Count first, followed by the Weft mesh count second
   
Square Mesh Tables
  The Square mesh tables list a standard meshes ranging from 2 mesh through and including  100.  The tables provide the complete range of wire diameters suitable for weaving each mesh count indicated.
  Many of these specifications are not considered as standard due to the limited popularity and are not produced although all the mesh count/wire diameter combinations are possible to weave and therefore are available by special (custom weave) order.
   
Square Mesh Stock Specifications
  This table lists all the popular stocked specifications and provides detailed at-a-glance information for each Mesh Count/Wire Diameter combination, the Industry Product Classification (Group) for each specification is identified and hyperlinked to the Product Group Page in addition to hyperlinked Product Data Sheets.
   
Woven Wire Product Specifications
  Screen Technology Group, Inc. (STG) has developed a universally recognizable system of Woven Wire Product Specifications that any person having only the most basic understanding of the wire weaving industry and woven wire products can easily interpret and cross reference with their own method of woven wire specifications and/or part numbering systems.
  Unfortunately several manufacturers (wire weavers) companies engaged in marketing and distribution of Woven Wire Products have developed their own system of specifying the products and the part numbers utilized to represent their products in a unique fashion in order to suggest exclusivity and thus limit fair competition by competitors who produce identical products.
   
Guide to Understanding 'Woven Wire Product Specifications'
   The word specification is defined as "to state explicitly or in detail" or "to be specific".
   
  To simplify the data storage and allow quick accessibility to the vast quantity of Specifications, many of the specifications have been sorted into Product Groups by relevance, basic characteristics, or the type of applications they may be best suited for.       
   
  Each type (or class) of Specification Group is accessible from the Woven Wire Cloth Products page. Each product specification group is provided with a brief description of the group and a link that will deliver you to the Product Specification Group page
   
  Screen Technology Group has published over 1,200 catalog products, all of which are well described in precise all inclusive technical details, among our extensive library of 28 Primary Product Specification Groups. These groups are all accessible from our Wire Cloth Products page.

ASTM A740 - 98(2014
Standard Specification for Hardware Cloth
Woven or Welded Galvanized Steel Wire Fabric
  This specification covers woven or welded galvanized steel wire fabric commercially known as hardware cloth. It is customarily used for window and screen door guards, tree guards, industrial machine guards, sand screens, and grain bins. It serves as a protective screen against rodents and is used for many other home, farm, and industrial purposes. The base metal of hardware cloth shall be of good commercial quality carbon steel wire. The zinc use in the galvanizing process shall be any grade of zinc. Hardware cloth shall be of wire woven or welded into squares or rectangles and then galvanized by the hot-dip process. The mesh size in inches shall be determined by counting the meshes for any interval of one continuous linear foot, in the direction of either the warp or filler wires, and finding the mesh size. All wire diameter designations in this specification for hardware cloth are finished sizes after galvanizing. Wire diameter for calculating purposes shall be the average measured diameters, after stripping, of at least five warp and an equal number of filler wires.
   
   
  ASTM A123 / A123M

Standard Specification for Zinc (Hot-Dip Galvanized)

Coatings on Iron and Steel Products
  This specification covers the standard requirements for hot-dip galvanized zinc coatings on iron and steel products made from rolled pressed and forged shapes, castings, plates, bars, and strips. This specification deals with both un-fabricated products and fabricated products, for example, assembled steel products, structural steel fabrications, large tubes already bent or welded before galvanizing, and wire work fabricated from uncoated steel wire. Also covered here are steel forgings and iron castings incorporated into pieces fabricated before galvanizing or those too large to be centrifuged (or otherwise handled to remove excess galvanizing bath metal).
   
  ASTM B134 / B134M Standard Specification for Brass Wire
  This specification establishes the requirements for round, hexagonal, octagonal, rectangular and square brass wire of UNS Alloy Nos. C21000, C22000, C22600, C23000, C23400, C24000, C26000, C27000, and C27400. The chemical composition, temper, annealed wire grain size, Rockwell hardness, and tensile strength requirements are detailed.
