Woven Wire Mesh Crimp and Weave Types
The reason why the woven wire mesh is widely used in different industries is inseparable from the diversified characteristics of the woven method. Due to the different weaving methods, each grid has its own characteristics.
By weaving, the mesh of the wire mesh can be 5 microns invisible to the naked eye, or it can be as large as a few centimeters. Through different connection methods of warp wire and weft wire, a variety of weave patterns can be produced, which usually depends on the application requirements.
Dongfu offers custom fabrication of all types of woven wire mesh.
Styles, Advantages, and Uses of Common Weaving Methods:
- The most commonly used is also the simplest weaving method.
- The diameters of warp and weft are the same, alternately overlapping each other to form the simplest mesh pattern. Used in most applications.
- The second commonly used weave method.
- The weft wire passes above and below the two warp wire to form square holes and diagonally woven patterns that look like twills.
- Twill weave can be made of metal wire with a larger diameter than plain weave, which can make the mesh more stable and obtain greater strength, density and corrosion resistance.
Plain Dutch Weave
A tight weave method, the diameter of the weft wire is smaller than the diameter of the warp wire, which allows the warp to be closer to each other, thereby forming a very tight, plain, over and under pattern.
Plain Dutch Weave does not have straight-through, clear openings like plain weave. On the contrary, this weaving method will form a tortuous path through which very fine filtration and particle retention can be achieved. At the same time, it provides many times higher mechanical strength than other common weaving methods.
- Plain Dutch Weave is often used in industrial filtration requiring high rigidity mesh.
Twilled Dutch Weave
- A weave style similar to Plain Dutch Weave is made with a twill weave. Weft wire with a smaller diameter is still used, and each weft wire passes through two warp wires, making the mesh proportional to the fineness. Compared with Plain Dutch Weave, the weave is tighter and the filtering effect is finer.
- Due to these characteristics, this woven wire mesh is commonly used in heavy filtration applications.
Reverse Dutch Weave
- This weaving method and Plain Dutch Weave method are roughly the same, the only difference is that the warp wire and weft wire are opposite (the diameter of the warp wire is smaller than the diameter of the weft wire).
- Compared to Plain Dutch Weave, larger diameter weft wire is woven more closely.
Rectangular or Off-Count Weave
- This is also a kind of plain weave wire mesh. There are different numbers of metal wires in the warp and weft directions, thus forming a rectangular opening shape.
- Rectangular openings are usually used for sifting and sizing operations to increase the “pass” capacity of the product.
- Although there is a slight sacrifice in accuracy, it reduces the material cost and is particularly suitable for applications that do not require very high accuracy.
Five Heddle Weave
- Each warp wire runs alternately up and down between a single weft and four weft wires. The pattern is staggered on successive warp wires, forming a parallel diagonal pattern.
- This weaving method allows for the use of wire thicker than other weaving methods for a specific mesh number. Its exclusive design supports improved drainage and flow features.
This is a twill weave style. The warp and weft are composed of a bundle or a group of smaller diameter wires, forming an exceptionally strong and tight mesh.
Pre-Crimped Woven Wire Mesh:
The pre-crimped woven wire mesh is woven from the crimped steel wire. Crimping the warp and weft wires before weaving can provide better stability and consistency for the wire mesh with a larger mesh spaced.
This woven mesh generally adopts plain weave, which has better wear resistance, better vibration resistance, and stable opening size. Commonly used in large industrial and architectural applications.
Over the years, it has developed a variety of crimping styles to improve its manufacturing efficiency, functionality, and aesthetics.
Plain Weave / Double Crimp Wire Mesh
- This is the most common type of woven wire. It is used where the opening is relatively small in comparison to the wire diameter.
- Square pattern wire cloth using warp and fill wires of equal size. Warp wires pass over and under fill wires in an alternating pattern at adjacent intersections.
Lock Crimp Wire Mesh
- This woven wire type 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.
- Made to hold accurate openings. Each intersection is formed with straight sections of fill wires woven within straight sections of warp wires. Fill wires are woven in an alternating pattern, top and bottom.
Intercrimp Wire Mesh
- This type of wire is used in coarse weaves of lighter gauge woven wire to provide greater stability, tightness of weave and maximum rigidity. It is very common in wire mesh openings larger than 1/2″ (12.7mm).
- Crimped warp wires filled at every other crimp with fill wires. Provides superior rigidity and greater stability. Popular for screens and architectural uses.
Flat Top Crimp Wire Mesh
- Usually starts at 5/8” (15.875 mm) opening or larger. This type of wire provides long abrasive resistant life since there are no projections on top to wear. Flat top woven wire offers the least resistance to flow and is very popular in certain architectural and structural applications where a smooth surface on one side is desirable.
- All crimping is offset to one side producing a single plan on the top which allows for the smooth flow of materials over the surface.
