Understanding Wire Thickness vs Hole Size in Woven Wire Mesh: Strength, Applications, and Best Practices

Understanding Wire Thickness vs Hole Size in Woven Wire Mesh: Strength, Applications, and Best Practices
  • Category: Woven Wire Mesh

Woven wire mesh is a versatile material used across numerous industries, from construction and agriculture to food production and DIY projects. A critical factor in determining the suitability of woven wire mesh for a particular application is the relationship between wire thickness and hole size.

This blog will explore how these two factors impact the strength and functionality of woven wire mesh. Drawing on examples from The Mesh Company’s comprehensive range, we’ll guide you in choosing the best specifications for your project.

The Basics: What Are Wire Thickness and Hole Size?

Wire thickness refers to the diameter of the wire used to create the mesh. Hole size, or aperture, is the space between wires. Together, they determine the mesh’s strength, flexibility, and suitability for various applications. For instance:
  • A thicker wire offers higher strength but reduces flexibility.
  • A larger hole size allows for greater airflow or water passage but reduces the overall structural integrity of the mesh.
 
Wire thickness and hole size work together to form the structural integrity of a woven wire mesh. A thicker wire provides greater strength and resistance to mechanical stress, while smaller holes contribute to tighter filtration and screening. However, when combined, their ratio determines the overall performance of the mesh. A balanced ratio ensures that the mesh maintains its desired functionality without compromising durability. For example, if you compare two meshes with the same hole size but different wire thicknesses, the one with the thicker wire will have a higher breaking point and be less prone to deformation under pressure. On the other hand, a mesh with larger holes and thinner wires will allow for higher airflow or visibility but will be less robust.

Calculating Strength: A Practical Example

The strength of woven wire mesh can be approximated by considering the cross-sectional area of the wire and the open area created by the holes. Here’s a simple calculation:

Wire Strength Formula:

The cross-sectional area (A) of the wire can be calculated using: A = π × (d / 2)2 where d is the wire diameter. This value correlates directly with the tensile strength and load-bearing capacity of the wire.

Open Area Formula:

The open area (OA) percentage can be calculated as: OA = (1 − (wire diameter / pitch)2) × 100 where pitch is the distance between the centres of adjacent wires (essentially, the sum of the wire diameter and the hole size).

How Wire Thickness Impacts Strength

The thicker the wire, the more durable and resistant the mesh is to deformation. For heavy-duty applications, such as security fencing or industrial sieving, wire thickness is a crucial factor.

Examples from Our Range:

11.1mm Hole, 1.6mm Wire, 2 LPI Stainless Steel Mesh

This ultra-strong mesh is perfect for high-impact applications like industrial sieving or protective barriers.

4.75mm Hole, 1.6mm Wire, 4 LPI Stainless Steel Mesh

With its balance of hole size and wire strength, this mesh is ideal for animal enclosures and structural reinforcements.

The Role of Hole Size in Mesh Performance

Hole size determines the type and size of particles the mesh can filter or block. Larger apertures are excellent for airflow and visibility, while smaller apertures provide finer filtration and greater privacy.

Examples from Our Range:

3 Mesh, 6.8mm Aperture, 304 Stainless Steel

The wide aperture makes this mesh perfect for ventilation and architectural applications.

40 Mesh, 0.42mm Aperture, 304 Stainless Steel

A much finer mesh for filtration tasks, such as sieving small particles or protecting against insects.

Wire Thickness and Hole Size: Finding the Right Balance

For most applications, it’s about striking the right balance between wire thickness and hole size. Here’s a breakdown:

Fine Apertures with Thin Wire

Example: 0.104mm Hole, 0.05mm Wire, 150 LPI Stainless Steel

Perfect for ultra-precise filtration in laboratory or medical settings.

Medium Apertures with Moderate Wire

Example: 1.23mm Hole, 0.355mm Wire, 16 LPI Galvanised Steel

Ideal for rodent control, soffit vents, and general-purpose use.

1.14mm Hole Woven Galvanised Mesh Wire Netting - 0.45mm Wire - 16 LPI

Large Apertures with Thick Wire

Example: 5.45mm Hole, 0.9mm Wire, 4 LPI Mild Steel

Excellent for heavy-duty projects like fencing and structural support.

Applications by Specification

Agriculture and Fencing

  • 13mm Galvanised Steel Chicken Wire is strong enough to secure livestock while allowing visibility and ventilation.
  • 5mm Hole, 1.5mm Wire Stainless Steel Sieve Mesh works well in sieving grain and other agricultural uses.

 

Industrial and Commercial

  • 0.223mm Hole, 0.14mm Wire, 70 LPI Stainless Steel is used for precision filtration in oil and gas.
  • 11.1mm Hole, 1.6mm Wire Stainless Steel is preferred for heavy-duty sieving and sorting.

 

DIY and Home Use

  • 1.23mm Hole, 0.35mm Wire Stainless Steel Mesh is suitable for fly screens and soffit ventilation.
  • 2.47mm Hole, 0.71mm Wire Galvanised Mesh is great for garden fencing and enclosures.

Benefits of Choosing the Right Wire Thickness and Hole Size

  • Enhanced Strength: Thick wires increase the durability of the mesh.
  • Optimised Functionality: The right hole size ensures the mesh performs its intended task effectively.
  • Cost Efficiency: Selecting the correct specifications avoids unnecessary expenses on unsuitable materials.

How to Select the Right Mesh

  • Define the Purpose: Identify whether you need the mesh for structural support, filtration, or visual barriers.
  • Consider the Environment: For outdoor use, opt for galvanised or stainless steel to prevent rust.
  • Evaluate the Load: For heavy-duty tasks, choose meshes with thicker wires and smaller apertures for added strength.

Maintenance Tips for Woven Wire Mesh

  • Cleaning: Regularly clean the mesh to remove dirt and debris, especially for finer apertures like 0.039mm Hole, 0.025mm Wire, 400 LPI Stainless Steel.
  • Inspection: Check for signs of wear or corrosion in outdoor applications.
  • Storage: Store mesh rolls in a dry, covered area to maintain their quality.
