Metal wire mesh and expanded metal mesh are two common types of metal mesh with some differences in structure, manufacturing process, and applications.
Metal wire mesh is typically woven from metal wires, providing high flexibility and strength. This type of mesh is often used for applications such as filtration, sieving, and separation, with different weaving patterns and wire diameters chosen to achieve specific sieving effects.
Expanded metal mesh, on the other hand, is produced by processing metal sheets through cutting and stretching methods to create an open mesh structure. This type of mesh is characterized by its lightweight, durability, ventilation, and transparency.
Metal wire mesh can be woven in different patterns, including:
Plain Weave: Metal wires cross each other once, forming a simple grid structure.
Twill Weave: Metal wires cross each other in adjacent pairs, creating a diagonal grid structure.
Hexagonal Weave: Metal wires interlace in a hexagonal pattern, forming a mesh with hexagonal apertures.
Square Weave: Metal wires intersect at right angles, creating a mesh with square or rectangular apertures.
◥Differences in Production Process between Expanded Metal Mesh and Woven Wire Mesh
Expanded metal mesh is manufactured from a single sheet of metal. This process involves simultaneous cutting and stretching of the metal sheet to form diamond-shaped (or other shapes, depending on the cutting pattern) apertures. The material is not woven or assembled; it is a single metal sheet manipulated to create the mesh structure. This process does not result in material wastage.
Woven wire mesh, on the other hand, is created by interlacing individual metal wires together, similar to weaving fabric. Individual metal wires are interlaced to create the mesh pattern. This process involves manufacturing separate metal wires and then assembling them. Some material wastage may occur during the trimming and finishing of woven wire mesh.
