What is Pre-Crimped Woven Wire Mesh?
Pre-crimped woven wire mesh is constructed of wires that have been crimped prior to weaving them together in a loom. Crimping the wires before weaving provides stability and consistency in larger spaced wire mesh. Various crimping styles have been developed over the years to improve manufacturing efficiencies, function, and aesthetics.
Flat top is really a modified version of Lock Crimp, except that all the crimping is offset to one side of the material. The result is a smooth plane in which all of the wire surfaces are flush with one another to give a flat appearance to the front of a Flat Top piece. The back side shows crimps approximately twice the height of a Lock Crimp. Originally developed to present a smooth surface to material flow, or as a backer screen for finer mesh, Flat Top is also used extensively in architectural applications.
The wire crimping process is critical in producing consistent, top quality woven wire mesh. Zhuoda continues to be the innovative force in architectural wire mesh manufacturing by exploring new ways of crimping and weaving wire. The following will provide more detail about the eight fundamental crimp styles: Plain, Lock, Intercrimp, Flat Top. These styles are building blocks and can be combined and modified to produce endless compositions of texture and reflectivity.
Plain Crimp is a simple zigzag style of crimping where warp and fill wires intersect at every available pocket. With Pre-Crimped material, the Plain Crimp is most common when Mesh to Diameter (MD) Ratios are 4:1 or less. This un-tooled look produces a smooth and subtle pattern.
Lock Crimp is a more modern and very versatile crimp style that has been largely overlooked for architectural applications. Unlike Plain Crimp, Lock Crimp is characterized by straight sections of wire connected by a well-defined 'bump' at the wire intersections. Lock Crimp yields material with superb dimensional stability and has a clean look that many designers find visually appealing. Lock Crimp works well at practically any MD ratio of 4:1 and greater.
While not really a fundamental crimp style, we choose to list it with the other crimp styles because of its widespread use. Intercrimp is simply Plain Crimp except that wire intersections occur only at every 3rd, 5th, 7th intersection, etc. This type of weave is practical only at MD ratios of 6:1 or more, and is best suited for ratios of 8:1 or more. We designate this style of weave as I3, I5, I7, etc.
