You can use wire cloth in many industries, from aerospace engineering to radio and microwave production. Also called wire mesh or wire fabric, this solution can filter materials, shield employees from hazards, insulate and much more.

Wire cloth is available in different styles, each with its own advantages. Here is a basic overview of wire cloth types.

Differences Between Welded and Woven Wire Cloth

There are two major types of wire cloth &#; woven and welded. Each product type is produced differently, presenting different benefits depending on the reason for the material. You can use both in a variety of applications and industries.

Welded Wire Cloth

Welded wire mesh is a highly durable material, often used for fencing or caging purposes. During construction, welded wire cloth is permanently welded at all intersections. This method makes the cloth rigid, holding a consistent shape during use. For industrial applications, welded wire maintains its shape, allowing it to fit precisely into structures and components without difficulties.

Here are the key features of welded wire cloth:

  • Applications: Many industries use welded wire cloth. Its high strength makes it a popular option for fencing and other barriers. Welded wire cloth is commonly used in industrial, agricultural and transportation fields, and it may also be used for air reduction in vents. Welded mesh is available in many different materials, including stainless steel and carbon steel. It can be made with heavy-gauge wire to a 0.025-inch-diameter wire, making it versatile for different uses.
  • Advantages: Due to the nature of its shape, welded wire mesh can achieve higher strengths using thinner wires. The cloth also has a higher percentage of open area.
  • Disadvantages: Welded wire cloth with particularly large openings might need to be custom manufactured, but most sizes are still available off the shelf. Similarly, due to the nature of production welded wire cloth cannot be made in fine mesh counts.

Woven Wire Cloth

This material consists of a series of metal wires interlaced to make a sheet of wire cloth. Instead of being welded together like welded mesh, woven wire is interlaced together. Wires can be woven together into particular diameters or patterns. The woven nature allows for more flexibility.

Features of woven wire cloth to know include:

  • Applications: You can make woven wire cloth out of steel, stainless steel, aluminum, brass, copper alloys and more. You can shape these materials in a variety of ways. Woven wire cloth is utilized in air filtration, baskets, doors and many other industries.
  • Advantages: In woven wire cloth, the openings can be much finer than in welded fabric. This makes it a great option for installations like filters or insect screens. Woven wire cloth is also extremely durable and can hold high weights.
  • Disadvantages: Some types of woven wire mesh could become unraveled on the ends, but you can avoid this with wire weaving techniques that offer high rigidity.

Different Types of Wire Weaving

If you select woven wire fabric, many types of weaves are available. Each style varies by mesh count, wire diameter specifications and the number of openings.

Here are two of the most common types of wire mesh patterns:

  • Plain weave: The plain weave is the most common type. It consists of same-sized diameter wires in a simple over-and-under pattern. The identical design creates the same amount of mesh openings in all directions.
  • Twill or Dutch weave: A twill weave is slightly more complicated than a plain weave, with each wire passing over and under two wires. This structure makes the twill weave more durable and available for larger diameters.

Types of Woven Wire Crimp Styles

Woven wire often uses a method known as crimping either before or during creation. If the mesh&#;s diameter is too big or too small, specialists crimp the wires before weaving. They send the wires through a crimper, and it individually shapes them so they can rest securely against one another. Crimped wire mesh makes the wire fabric stronger and more rigid.

Here are a few of the crimp styles available for wires:

  • Lock crimp: The lock crimp is a more modern style. It consists of straight sections of wires, where each wire is crimped at each intersection. Lock crimp wire mesh creates an aesthetically pleasing pattern and is also very stable.
  • Double intermediate crimp: A double intermediate crimp forms a square-like pattern with wires of equal size. They pass over and under one another at adjacent intersections with equal lengths.
  • Intercrimp: An intercrimp style uses intersecting wires at every other intersection. For example, wires might intersect at the third intersection, the fifth intersection and so on. This style provides high rigidity and is popular in architecture.
  • Flat top: A flat top crimping style is similar to a lock crimp wire cloth, but all crimps are offset to one side. This design creates a flat appearance on the front, making it ideal for materials to flow smoothly across it. It&#;s also commonly used in architecture.

How to Match Weave and Crimp Style

By matching your crimp and mesh weaving style, you can create an optimized woven wire cloth. The right combination of weaving and crimping styles can make your wire mesh more sturdy or flexible. But with all the crimping options and wire cloth terms, it&#;s sometimes tricky to know which style fits you best.

Here are three considerations for picking your weave and crimp styles:

1. Wire Diameter

The wire diameter is the width of each wire. The diameter directly effects how much open space exists between wires.

You can choose diameter according to what conditions your wire will face. For instance, if your wire will mostly encounter small amounts of sand, you wouldn&#;t need an extremely thick diameter. Usually, the thicker and stronger your wire is, the more you avoid future fixes and replacements.

2. Mesh Count

Your wire&#;s mesh count is the number of openings within an inch. So, if you have a 300 mesh wire, there are 300 openings within one inch in any direction of the wire. When selecting mesh count, consider how many materials will pass through your wire and how many of those you want to block.

If you choose the wrong mesh count, unwanted materials or substances might reach underneath surfaces. Or, too many substances might build up on your mesh because they can&#;t pass through.

3. Micron Rating

A micron rating is a precise distance between your wires. Once you determine your diameter and mesh count, you can decide upon the best micron rating for your wire&#;s purposes. People often use micron ratings for wire mesh meant for filtration. The correct micron measurement allows for proper filtration while maintaining a consistent substance flow.

The Ultimate Guide To the Industrial Woven Wire Mesh

To facilitate the centuries-old weaving process, wire mesh suppliers must employ specialized weaving looms designed to work with metallic wires. These looms consist of seven components: a warp beam, warp wires, heddle frames, weft wires, a rapier band, a reed, and a front take-up mechanism.

  • The warp beam is a cylindrical beam that is used to wind the warp wire after the volume and length of the wires are calculated based on the specifications of the mesh.

  • Warp wires are the wires that run vertically and are threaded through the entire loom.

  • The heddle frames are holsters that are used to organize and separate the warp wires. Looms set up to produce a square mesh may have two sets of heddle frames, whereas more complex filter cloth weaves may have more.

  • Weft wires are the wires the run horizontally and are typically fed by a separate spool of wire.

  • The rapier band system is responsible for threading the weft wire through the sets of warp wires between heddle frame movements.

  • The reed is one of the most essential elements of a weaving loom as it is used to position the warp wires they will be woven in and drive the weft wires into their exact potion.

  • The front take-up mechanism rolls the woven mesh once it is fully woven.

 

The Weaving Process

To initiate the weaving process, a loom operator will attach and arrange the individual wires on the warp according to their position in the weave. To prevent entanglement, these wires are housed in a wire housing unit known as a creel.

Once attached, the warp beam is wound, allowing the proper length of wire to be wrapped around the beam.

Each wire wound on the warp beam is threaded through its own heddle in a specific heddle frame then carefully threaded through the reed openings based on their order in the weave. At this point, the warp beam, heddle frame assembly are transferred to the weaving hall, and the remainder of the loom is assembled.

NOTE: A great deal of attention to detail must be applied when threading the wire through the heddle frames and reed, as this process control how accurate the mesh specifications are.

Once the loom is fully assembled and the wires are properly threaded, the weaving process can begin.

When first initializing the weaving loom, the warp beam unwinds slightly to feed a small increment of wires. At the same time, the front take-up mechanism winds the same increment of wires to maintain the required tension to produce high-quality mesh.

Once these movements are made in conjunction, the heddle frames shift to separate the wires. In a two-heddle frame system, the first heddle frame lifts one half of the wires, and the second heddle frame drives the other half of wires down.

While the two sets of wires are separated, a weft wire, typically fed from a wire spool that is separated from the creel and placed next to the loom, is shot between the wires by the rapier band. The rapier band then moves back to its resting position.

It's at this point that the reed propels the weft wire to its final position, creating the precise cross-sections that wire mesh is known for. Once the weft wire is positioned, the reed returns to its resting position.

This marks the completion of the first interval.

To continue the weaving process, the warp beam and front take-up mechanism make the same slight, rotating movement to begin another interval. At the same time, the heddle frames will switch potion, wedging the previous weft wire as the two sets of wires are separated in the opposite direction.

These joint movements repeatedly continue until the desired length and mesh specification is woven.
