Mesh Types Overview

IWW provides a vast array of mesh in different weave patterns and materials. Our offerings include Wire Cloth, Tri-Mesh, Tri-Lock, Inter-Crimp, Lock-Crimp, and Single-Chute. Below, you will find descriptions and examples of these patterns.

Wire Cloth
Wire Cloth, commonly known as Double Crimp, is one of the most widely used types of wire mesh. The size of the opening is determined by the distance between the crimps. By varying the distance between the crimps on the running and cross wires, we can also produce wire cloth with rectangular openings.

Inter-crimp
Inter-crimp involves the use of additional crimps between intersections to enhance rigidity and locking tightness, especially for light wires in relation to the wire opening. This construction method allows for rectangular and square openings in a variety of sizes.
 

Lock-Crimp
Lock-Crimp features straight wire sections connected by a distinct 'bump' at wire intersections, effectively 'locking' the wires together to prevent any movement.

Tri-lock
Tri-lock, also known as triple-chute, secures wires while permitting slight vibration to keep openings clear. IWW can manufacture Tri-lock with 1", 2", 3", and 4.5" long openings. 

Tri-mesh
Tri-mesh combines triple-chute and inter-crimp weave patterns. The intermediate crimps in Tri-mesh enable longer opening sizes while retaining rigidity at smaller wire diameters. 

Specialty Meshes
Specialty meshes merge the styles mentioned above to create various mesh styles.
 

 Wire Mesh Weave Styles

Plain/Double: The plain weave is the simplest and most common weave pattern, resulting in square openings with wires of equal size in both directions. Each warp wire alternately passes over and under fill wires at right angles in both directions.

Twill Square: This weave pattern has each warp and shute alternately woven over two and under two warp wires, creating a parallel diagonal line appearance. This allows the use of heavier wires for specific mesh counts compared to the plain weave, providing greater load capacity and finer filtration applications.

Twill Dutch: This filter cloth offers higher strength compared to regular Dutch weaves by packing more wires in a given area. Each shute wire passes over two warp wires and under two, producing square openings. It can filter particles as fine as 2 microns in diameter, making it suitable for fine filtration tasks.

Reverse Plain Dutch:  This filter cloth has a higher count of wires in the warp and a smaller count in the shute, reversing the method used in plain and twilled Dutch weaves. The warp wires have smaller diameters and touch each other, while the heavier shute wires are tightly woven together.

Plain Dutch: Mainly used as a filter cloth with diagonally slanting openings that are not visible when looking directly at the cloth. This weave has a coarser mesh and wire in the shute direction, resulting in a compact and firm mesh with high strength.

Woven Wire Cloth Crimp Styles

Pre-crimping is typically found in coarser wire cloth or space cloth specifications, ensuring accuracy and consistency in opening sizes. Pre-crimping adds strength and rigidity to the wire cloth by allowing warp and shute wires to nest securely, restricting random movement. Here are some of the custom crimp styles offered:

Lock Crimp: Designed for precise openings. Each intersection is formed with straight sections of fill wires woven within straight sections of warp wires, maintaining an alternating pattern of top and bottom.

Double Crimp: A square pattern wire cloth using warp and fill wires of equal size. Each warp wire alternately passes over and under fill wires in adjacent intersections.

Intercrimp: Crimped warp wires are filled at every other crimp with fill wires, providing superior rigidity and stability, making it popular for screens and architectural applications.

Flat Top:  All crimping is offset to one side, producing a single plane on top, which allows for the smooth flow of materials over the surface.
