|Wires are woven together to create wire mesh or called wire mesh in different weave patterns, such as plain weave and twilled weave. The most common materials used to create woven wire cloth are metallic including carbon steel, pre-galvanized steel, aluminum, copper/brass/bronze and stainless steel. Other materials such as Monel, Hastelloy, Inconel, Titanium or other nickel alloys can also be woven into wire mesh. The common finish option can be galvanizing, chrome plating, copper plating, PVC dipping and powder coating in different colors. Carbon steel woven wire cloth is available upto 100 mesh.|
Wire cloth or wires can be sintered together into Sintered Laminates or Sintered Felt.
Space Screen and Square Mesh in 10 mesh and coarser are typically woven from pre-crimped wires. Such material remains stable and rigid after the crimping process. Wire cloth woven from pre-crimped wires provides accurate openings and is woven tighter than plain weave. Pre-crimped weaves are preferred for vibrating screens, decoration and many other applications where sizing is critical.
I. CRIMPED STYLES
Our pre-crimped woven wire cloth is available in double weave, inter-crimp, lock-crimp, double lock-crimp, triple shoot and flat top woven styles, and they are ideal for architectural applications.
|1. Double Crimp: |
The most common type. Also referred to as "Over and Under" this weave is commonly used for screening operations in smaller openings in comparison to the wire diameter. Used for medium to heavy wire in relation to screen opening size.
|2. Inter Crimp: |
Used in coarse weaves of lighter gauge wire to provide greater stability, tightness of weave and maximum rigidity. Very common in mesh openings larger than 1/2" (12.7mm).
|3. Lock Crimp: |
Also known as Scalping Weave. Due to the deep crimps which lock the wires in place. It is used only in coarse specifications to maintain the accuracy of weave throughout screen life, where the opening is large with respect to wire diameter.
|4. Double Lock
Single shoot oblong openings solve minor blinding problems for better flow.
|5. Triple Shoot: |
Long openings will keep sticky or wet material flowing freely. Weave holds wires securely yet permits slight vibration to keep openings clear.
|6. Flat Top: |
It usually starts at 5/8" opening or larger providing long abrasive resistant life, since there are no projections on top to wear and also offers least resistance to flow. It improves material flow with a much smoother, flatter surface than other weaves, and maintains accurate openings, and is very popular in certain architectural and structural applications where a smooth surface on one side is desirable.
II. WEAVE PATTERNS
|1. Plain Weave: |
The most common weave, with the same diameter warp and weft wires woven in a simple over and under pattern. It produces screens with the same mesh count in both directions in square openings. Sometime the opening is in Rectangular or called Off-Count" weave. Warp and weft wire diameters are generally the same.
|2. Twill Square: |
Each weft wire alternately passes over two, then under two successive warp wires and each warp wire passes alternately over two and under two successive weft wires, in a staggered arrangement. Twill weave can be made from larger-diameter wires than would be possible in plain square weave to obtain greater strength, density or corrosion resistance. Twill weave is normally used to allow a heavier than standard wire diameter in association with a given mesh.
|3. Plain Dutch
Also known as Plain Dutch (Hollander) weave, woven in a plain, over and under pattern. While the warp wires remain straight, the weft wires are plain woven to lie as close as possible against each other in a linen weave forming a dense strong material with small, irregular and twisting passageways that appear triangular when diagonally viewing the weave. A thinner, smaller diameter weft wire is used; these are driven very close together creating a very tight weave.
Dutch weaves do not have a straight-through, clear opening as do most plain weave styles. Instead the weave style creates a tortuous path through which very fine filtration and particle retention can be achieved. Dutch weaves may be specified by "mesh count" or "absolute filter rating."
|4. Dutch Twill
Similar to Plain Dutch except woven in the Twill style with a double layer of weft wires. Each wire passes over two wires then under two wires, still utilizing a smaller-diameter weft wire, allowing an even tighter weave and even finer filtration than Plain Dutch weave. There are no apertures in the true sense of the word as the filtrate follows a sinuous path through the depth of the wire cloth.
|5. Reverse Dutch
The same weave as Plain Dutch except the warp and weft wires are reversed; I.E., the warp wires have a smaller diameter than the weft wires. The larger weft wires are woven closer together than would usually be seen in a Plain Dutch weave.
