What is Metal Woven Wire Mesh?

Metal Woven Wire Mesh is created by weaving together wires at right angles. This method results in a sturdy and flexible mesh that can be used for a variety of applications, from filtration to architectural design. The woven pattern provides strength, making it suitable for both heavy-duty and light-duty uses.

What is Expanded Metal?

Expanded Metal, on the other hand, is made by taking a solid sheet of metal and cutting it in a way that allows it to be stretched and expanded. This process creates diamond-shaped holes, giving the material its distinctive appearance. Expanded metal is particularly effective for applications that require ventilation or light passage.

What are the main differences between Metal Woven Wire Mesh and Expanded Metal?

1. Manufacturing Process: As mentioned, Metal Woven Wire Mesh is woven, while Expanded Metal is expanded from a solid sheet. This affects the characteristics and applications of each type.
2. Strength: Metal Woven Wire Mesh is typically stronger and more durable due to its woven construction, making it suitable for heavier loads. Expanded Metal is also strong, but its strength often depends on the thickness of the original sheet.
3. Flexibility: Woven wire mesh is more flexible, allowing for easy shaping and installation. Expanded metal is rigid and holds its shape, which can be beneficial in certain applications.
4. Open Area: Expanded Metal generally has a higher open area percentage, making it ideal for applications needing ventilation or drainage. Metal Woven Wire Mesh has a lower open area, which can be useful for applications wanting more solid coverage.
5. Applications: Metal Woven Wire Mesh is used in various industries, including construction, agriculture, and aerospace. Expanded Metal is often seen in grating, fences, and security products.

Which is better for specific applications?

The choice between Metal Woven Wire Mesh and Expanded Metal largely depends on your project's specific requirements:

1. For filtration needs: Choose Metal Woven Wire Mesh because its smaller openings and tighter weave make it exceptionally effective for filtering liquids and gases.
2. For security fencing: Expanded Metal is more practical here, as its rigid structure provides a solid barrier while allowing visibility and airflow.
3. For architectural designs: Both can be used, but Metal Woven Wire Mesh allows for more intricate designs due to its flexibility, making it a popular choice among architects.
4. For strength and load-bearing applications: Metal Woven Wire Mesh stands out as it is generally more durable and can support heavier loads.
5. For aesthetic purposes: Metal Woven Wire Mesh offers a sophisticated appearance that might appeal to those seeking a unique look.

Conclusion: Which Wins?

Ultimately, the decision between Metal Woven Wire Mesh and Expanded Metal comes down to your specific needs. If you require flexibility, strength, and tight filtration, Metal Woven Wire Mesh is likely the better option. However, for applications focusing on airflow and visibility, such as security and fencing, Expanded Metal may serve you best. Consider the factors discussed here to make an informed choice that meets your project's requirements.
