Tips for Cutting Expanded Metal to Avoid Sharp Edges

Expanded metal is a versatile material widely used in construction, industrial, and interior design projects. Its strength, unique appearance, and ability to support heavy loads make it a popular choice.
However, one challenge when working with it is that the cuts often leave sharp edges. Besides the risk of injury to workers, this can also affect the aesthetics and safety of the installation.
Check out these tips to ensure neat, safe, and professional cutting of expanded metal!

1. Use the Right Cutting Tools
Choosing the right cutting tools significantly impacts the final result. Some recommended tools for cutting expanded metal include:

An angle grinder with a thin metal blade for fast, clean results.

A metal shear for precise cuts without a lot of chips.

Avoid using a regular saw, as it can cause tears and leave sharp edges in the metal.

2. Ensure the Sheet is Securely Clamped
Before cutting, secure the expanded metal with metal clamps or clamp it to the workbench to prevent shifting.
Small vibrations during cutting can cause uneven work and leave sharp edges on some sides.

3. Cut at a Steady Speed
Maintain a steady cutting speed and pressure throughout the process. Avoid cutting too fast or applying too much pressure, as this can cause vibrations and result in uneven edges.

4. Smooth the Edges After Cutting
An important step after cutting is to smooth the metal edges.
Use a fine-grit grinder, metal sandpaper, or a steel file to remove any sharp edges.
Besides making the final product safer, this step also improves the aesthetic appearance, especially if the expanded metal is used for fencing or interior elements.

5. Protect the Edges with an Anti-Rust Coating
Cut edges are susceptible to corrosion.
Once smooth, apply a coat of anti-rust paint, zinc primer, or liquid galvanizing coating to ensure the expanded metal is durable and resistant to damage, even when used outdoors.

Conclusion
Cutting expanded metal requires extra technique and care to ensure the results are not only strong, but also safe and durable.
With the right tools, a stable technique, and additional protection after cutting, you can achieve professional results without the risk of sharp edges.
