Knitted Mesh Rolls JHJ manufactures mesh rolls in a wide range of materials and capabilities for a number of industrial applications. Mesh is normally specified by the number of stitches per cm. Our range of meshes is considerable, but for practical purposes there are, typically, 0.5 stitches per cm to 6 stitches per cm. Meshes can be grouped into five broad categories: fine, medium-fine, standard, coarse and super-coarse. However these divisions can cover a wide range of products. By using various filament diameters and mesh sizes, along with different crimping, calendaring, folding, layering and rolling, the choice is almost unlimited. Knitted mesh can be all metal for round or flat wire steel mesh, including Monel, galvinized steel mesh, tin plated copper clad steel (SN-FE-CU), tinned copper, stainless steel, silver-clad copper, aluminium and copper. Nickel-plated copper and phosphor bronze gaskets are available to special order.
