It is clear that The Mesh Company specialises in providing a diverse range of mesh materials, catering to a wide spectrum of industrial and architectural needs.

This guide focuses on four primary types of mesh:

  • perforated metal mesh
  • expanded metal mesh
  • welded wire mesh
  • woven wire mesh

Each type presents distinct characteristics and applications, making them suitable for various tasks, from reinforcing concrete in construction to enhancing aesthetic appeal in architectural designs.

Perforated metal mesh, a highly versatile and commonly used material, is characterised by its array of precise holes or perforations. There are various shapes, sizes, and patterns of perforations that are available with this mesh type, which make it particularly adaptable to a wide variety of different applications due to its level of customisation.

It is created by punching sheet metal panel. This gives a strong product with a lot of potential hole shapes and sizes. 

The Mesh Company offers an extensive selection of perforated metal mesh options, including but not limited to:

Each variety caters to different requirements, ranging from structural applications to aesthetic enhancements. Specifications such as hole size, pitch (distance between holes), and thickness determine a mesh’s suitability.

There are numerous advantages to using perforated metal mesh. With excellent ventilation capabilities, it is ideal for air flow systems, and its sound absorption qualities make it ideal for acoustic panels. As a result of its filtration properties, perforated mesh is a preferred choice for a variety of industrial processes. The aesthetic appeal of perforated metal mesh cannot be overstated, as its use in architectural designs provides both functional and decorative benefits.

Common applications of perforated metal mesh extend to various sectors. This material is used in architecture for façade cladding, decorative panels, and privacy screens, providing a blend of visual appeal and practicality. Perforated mesh panels are widely used in auditoriums, conference rooms, and other spaces where sound control is essential. Using this mesh in air ventilation systems ensures efficient air flow while filtering out unwanted particles. In both industrial and architectural settings, perforated metal mesh is versatile and useful.

Expanded metal mesh is a distinctive and highly functional material widely used in various industrial, architectural, and security applications. It is often likened to perforated metal as it has similar characteristics for the end use. 

As a result of its unique manufacturing process, this mesh stands out from other types of mesh. As a result of this process, the solid metal sheet is slit and stretched, resulting in a one-piece construction that does not unravel or fray as a result of the process. In this way, a mesh with diamond-shaped openings is created, resulting in a pattern that is both strong and lightweight thanks to its diamond-shaped openings. As a result of this production method, the material retains its structural integrity, which results in a high strength-to-weight ratio and a long service life.

The Mesh Company offers a broad spectrum of expanded metal mesh, catering to diverse needs and specifications. Some of the offerings include:

These variations differ not only in material composition – aluminium versus mild steel – but also in dimensions and thickness, allowing customisation in accordance with specific project requirements.

Corrosion-resistant and lightweight, aluminium expanded mesh is ideal for outdoor and architectural applications. In contrast, mild steel expanded mesh is prized for its strength and durability, making it suitable for more demanding structural applications.

Expanded metal mesh has a wide range of applications and advantages. Durability is one of its key strengths. Because it is made from a single piece of metal, it is extremely durable and long-lasting. The security aspect of expanded metal mesh is also important. Providing a secure environment without compromising visibility or air flow, its robustness makes it an excellent choice for protective barriers and fencing.

It also allows air, light, and visibility to pass through. In HVAC systems, machinery guards, and architectural facades, this feature is particularly useful when ventilation is required while security and visibility are not compromised. Openings in the mesh allow adequate airflow and light penetration while preventing unwanted access.

Welded wire mesh is a robust and versatile material widely used across various industries due to its exceptional strength and adaptability. Steel wires are precisely welded at their intersections to form a grid-like structure. Parallel longitudinal wires are laid out, then intersected with transverse wires. A solid bond is formed at each junction by welding the wires together, usually by electric fusion. The mesh produced by this method is exceptionally strong and rigid, with uniform openings.

The Mesh Company offers a diverse range of welded wire mesh products, catering to a wide array of applications and requirements. These products vary in several key aspects, such as:

  • Hole sizes: Ranging from fine meshes with small openings to larger grids.
  • Wire gauges: Different thicknesses of wire are used, affecting the mesh’s strength and flexibility.
  • Materials: Options include galvanised steel, stainless steel, and PVC-coated wire, each providing different levels of durability and corrosion resistance.

For example, their offerings include:

These variations allow for a range of applications, from light-duty tasks to heavy-duty industrial uses.

One of the most significant properties of welded wire mesh is its strength and durability. At each intersection, welding creates a strong bond that maintains the mesh’s shape and integrity, even under stress or when cut. Due to its strength, it is an ideal choice for applications requiring robust structural support.

Material selection plays a crucial role in corrosion resistance. For example, galvanized steel offers excellent corrosion and rust resistance, making it suitable for outdoor or humid environments. Stainless steel mesh can also be used in environments with higher corrosion resistance, such as marine or acidic environments. The PVC coating further enhances the durability and lifespan of welded wire mesh.

Known for its precision weaving process and wide range of applications, woven wire mesh is a highly intricate and versatile material. Weaving metal wires together in a similar manner to weaving cloth results in a mesh with uniform openings and a flat surface. A stable and consistent pattern is formed by interlacing longitudinal (warp) and transverse (weft) wires at right angles. This process allows for a variety of weave patterns, including plain weave, twill weave, and Dutch weave, each offering distinct characteristics.

Mesh Company offers a wide selection of woven wire mesh in a variety of materials, wire diameters, and weave patterns. From micron-sized meshes to coarser varieties, they cater to a wide range of needs. Their range includes the following examples:

Depending on wire diameter, hole size, and number of lines per inch, these varieties can be customised to suit specific project needs. Due to their strength, flexibility, and corrosion resistance, stainless steel is commonly used for woven wire mesh.

One of the most valuable characteristics of woven wire mesh is its precision and versatility. Due to its tight tolerances and specific mesh counts, it is ideal for applications that require precise filtration and separation. With its variety of weave patterns, it can also be tailored for specific strength, permeability, and aesthetic needs.
