3. Select the Mesh Pattern

The pattern of the expanded metal mesh affects its strength, flexibility, and appearance. Common patterns include:

Standard (or Regular) Mesh: The most common type, characterized by diamond-shaped openings. It provides a balance between strength and open area.

Flattened Mesh: Created by rolling the standard mesh, which flattens the peaks and produces a smoother surface. This type is often used in applications where a smooth finish is required, such as walkways or cladding.

Micro-Mesh: Features smaller openings and is used in applications requiring finer filtration or a more delicate appearance, such as in air filters or speaker grilles.

Heavy Mesh: Has larger and thicker strands, offering greater strength and durability, suitable for load-bearing applications like platforms and stair treads.

The choice of pattern should align with the functional and aesthetic needs of your project.

4. Consider the Thickness and Strand Width

The thickness of the metal and the width of the strands are crucial factors that determine the strength and rigidity of the expanded metal mesh:

Thickness (Gauge): Thicker materials provide more strength and durability but may be heavier and less flexible. Thinner gauges are more suitable for decorative purposes or applications where weight is a concern.

Strand Width: Wider strands offer more strength and rigidity but reduce the open area, affecting airflow, visibility, or light transmission. Narrower strands increase the open area but may be less sturdy.

The balance between thickness and strand width should match the load-bearing requirements and desired appearance.

5. Consider the Open Area

The open area of the expanded metal mesh, determined by the size and shape of the openings, influences factors such as:

Visibility and Light Transmission: Larger openings allow more light and visibility, making them suitable for architectural facades or fencing.

Copper mesh is also known as copper screen or copper wire mesh. The copper mesh is a square weave mesh that it woven by a copper wires which has great electrical and thermal conductivity. The copper is a malleable and soft material. A copper mesh is widely used as electromagnets interference. It can also be used as a shield for radio frequency interferences.  It is also used as a window screen or in different industries as filtration and separation.

Copper mesh are known to have long service lives and as a sign of wealth and prestige. It is for these features that they are usually used as decorative house facades in construction. They are also used as reliable and durable plastering reinforcement material for ceilings and walls.

Classification

Copper meshes can be further classified into medium, fine and coarse wire mesh. This is of course depending on the wire specification. The medium copper mesh includes the meshes that are in the range of 12 x 12 meshes up to 40 x 40 meshes. The fine meshes include the 50 x 50 mesh, 60 x 60, 80 x 80 and 100 x 100 mesh. The coarse mesh on the other hand include 2 x 2 mesh, 4 x 4, 6 x 6, 8 x8 and 10 x 10 mesh.

Copper mesh can also be subdivided into three types depending on the materials that it is made up namely the purpose copper mesh, brass wire mesh and the phosphor copper mesh.

Purple copper mesh.

The material used is purple copper wire which is 99.8 percent pure copper. This mesh is non-magnetic and is able to bear the pressure in grinding. It is widely used during filtration of electron beam as well as in electron display screen.

Brass wire cloth or brass wire mesh.

Material used is brass. There are different proportions and one of these is the 65 brass. For this material, it has 65 percent while the zinc is 35 percent. Another brass is the 80 brass material which contains 80 percent of brass proportion with the zinc only 20 percent. The brass wire cloth is non-magnetic, has good ductility and is wear resistant. It can be used as porcelain glass and clay, filtering gas and liquid, powder, and is also used to screen different granules.

Phosphor mesh.

This is also the alias used for tin bronze mesh. The material that makes up the phosphor mesh is phosphor copper wire. The proportion is 85 to 90 percent copper and the tin is about 5 to 15 percent. The phosphor mesh is non-magnetic; it is able to bear the grind alkali and ache and is also ductile.

Mesh sizes and shape

There are different mesh sizes. The usual wire diameter is in the range between .3mm to 1.2mm. The preferred diameter for the wire mesh by most consumers is .6mm. The opening size of the mesh on the other hand is usually in between 4mm to 6mm. The mesh is shaped into square and the copper bare mesh has the spacing of 300 x 300mm.

Advantages of copper mesh

Tensile endurance

Considering that copper is strong in addition to being versatile, it increases the reliability of the overall system even under unfavorable conditions.

Non-reaction with water

Copper does not react with water, but can react with oxygen in the atmosphere and also forms a dark brown layer of copper oxide. In contrast to the oxidation of iron by moist air, this formed layer of copper oxide prevents further deterioration.

Adaptability

Copper wire mesh is flexible and easy to install and handle. It can be quickly attached by welding, brazing or soft soldering. Its versatility means it can be used to adapt to different style configurations.

Durable and maintenance-free

Copper cable mesh is durable and requires very low maintenance, making it the preferred choice for many mechanical and industrial systems. It does not require any type of finish to prevent corrosion.

Biostatic

Bacteria will never expand on the copper grid.

Sustainability

Copper is recyclable and does not lose its high quality, whether you use it in its original state or in manufactured products. By comparison, copper is one of the most recyclable metals after lightweight aluminum and iron.

Safety and security.

It does not melt or burn continuously. Copper cable mesh does not carry fire, especially through walls, ceilings and floors. It also does not decay directly into toxic gases.
