Woven Wire Mesh

Woven wire mesh table


 Also known as wire gauze or wirecloth, woven wire mesh is an extremely versatile material suitable for many filtration and straining applications. It is woven to fine limits and can be used to separate out contaminates of a given size. 


Available in Stainless Steel, Mild Steel, Monel, Phosphor Bronze, Brass & Copper


Mesh Count: the number of apertures or wires in a linear inch. 

Aperture: the hole size or gap between wires.

Open Area: the proportion of aperture expressed as a percentage of the whole area.

Warp: the wires running lengthwise in a roll of mesh.

Weft: the wires running transversely across the mesh width.


Perforated Metals

Perforated metal


Perforated sheet metals come in a wide variety of materials, thicknesses, aperture shapes and sizes.

It can be used as a filtration media on its own or in conjunction with woven wire mesh to give support and rigidity.


Stainless steel, mild steel, copper and brass perforation are widely utilised for filtration products although other materials such as aluminium and other metals are also available.


Hole Shape: round or sometimes square holes are commonly used for filters and strainers. Other shapes such as slotted, rectangular or even octagonal are available although these are generally used for architectural applications.

Hole Size: (D) the aperture width of the hole  (has to be larger than the material thickness)

Pitch: (P) the distance between hole centres. 60º or 45º staggered triangular pitch is the most widely used.

Bar: (B) the width of material between the holes
