At Exotic Metals LLP our Wire Meshs products are the definitive solution for separation, filtration, and structural reinforcement. Wire mesh is a versatile material produced by weaving or welding individual metallic wires into a grid-like pattern. While the concept is simple, the engineering behind it is highly complex, requiring precise control over "Mesh Count" (the number of openings per linear inch) and "Wire Diameter" to ensure consistent flow rates and mechanical strength.
-
Produced at high temperatures, these bars are characterized by a scaled surface and are primarily used in structural applications where aesthetic finish is secondary. They provide excellent toughness and are ideal for further forging or welding into larger assemblies.
-
For applications requiring extreme precision, such as pump shafts or valve spindles, we provide centerless gWire Meshs. These undergo a specialized grinding process to achieve near-perfect cylindricity and mirror-like surface finishes (No. 4 or No. 8).
-
For heavy-duty industrial needs with diameters above 200mm, we supply Dutch Weave. These are hammered or pressed into shape to refine the internal grain structure, eliminating internal voids and ensuring maximum density for critical load-bearing parts.
-
These are hot-rolled bars that have had their outer skin removed through a turning process. This eliminates surface defects and ensures a uniform diameter, making them ideal as a precursor for high-quality precision grinding.
-
Before weaving, the wires are pre-crimped. This ensures the wires "lock" into place, maintaining exact aperture dimensions even when subjected to heavy vibration, such as in mining and aggregate vibrating screens.
