The process of cutting expanded metal can be a bit more challenging than cutting other types of metal – you need the right tools, the right technique, and a little extra patience to do it right. A trained professional, however, can use the right information, tools, and methods in order to cut expanded metal precisely without damaging the equipment or materials.
Preparatory Steps Before Cutting Expanded Metal
Before embarking on the process of cutting expanded metal, it is essential to follow a series of preparatory steps to ensure a smooth and safe operation. These steps are crucial in achieving accurate cuts and maintaining the integrity of the expanded metal sheet. Here’s a comprehensive guide to the preparatory measures:
1.Safety First
Always prioritize safety. Ensure that you have the appropriate personal protective equipment (PPE), including safety glasses, gloves, and ear protection. Additionally, work in a well-ventilated area or use respiratory protection if needed.
2.Select the Right Tools
Depending on the thickness and type of expanded metal, choose the appropriate cutting tools. Common tools include angle grinders, tin snips, plasma cutters, or shears. The tool selection should align with the specific requirements of your project.
3.Inspect Tools and Equipment
Before starting, thoroughly inspect the chosen cutting tools and equipment. Check for any damages, ensure blades are sharp, and confirm that all safety features are in proper working condition.
4.Measure and Mark
Accurate measurements are crucial for precise cuts. Use a tape measure and a straight edge to mark the cutting lines on the expanded metal sheet. Double-check the measurements to avoid errors.
5.Secure the Expanded Metal
Properly secure the expanded metal sheet before cutting to prevent movement during the process. Use clamps or a secure worktable to hold the material in place, ensuring stability and reducing the risk of accidents.
6.Consider Lubrication
Depending on the cutting method and tool used, applying a suitable lubricant may enhance the cutting process and extend the life of the cutting tool. Consult the tool manufacturer’s guidelines for recommendations.
7.Wear Appropriate Clothing
Choose clothing that covers your body and provides additional protection. Loose-fitting clothes, long sleeves, and long pants can help minimize exposure to sparks and debris generated during the cutting process.
8.Plan for Waste Disposal
Consider how you will handle the waste material generated during cutting. Have a designated area for collecting and disposing of metal scraps, ensuring a clean and organized workspace.
9.Review User Manuals
If using specific cutting tools or machinery, take the time to review the user manuals. Familiarize yourself with the recommended operating procedures, maintenance requirements, and safety guidelines.
10.Double-Check Power Sources
For powered tools, ensure a stable power source and confirm that all electrical connections are secure. Follow proper procedures for connecting and disconnecting power to the tools.

Expanded Metal Cutting Tools
The first step to correctly cutting expanded metal is finding the right tools. The following equipment is essential:
- Cutting tool: Consider the size and nature of the expanded metal you need to cut. Then, choose a grinder, drill, saw or laser tool.
- Measuring device: Either a tape measure or a ruler will work fine.
- Clamps: These tools hold the metal in place while you cut.
- Protective gear: It’s crucial that you stay safe during the process, which includes safety glasses, a protective apron or cloth, gloves and safety boots.
Cutting Tips
1.Adjusting Cutting Speed
Cutting speed is a crucial factor influencing both cutting quality and efficiency. Generally, cutting too fast or too slow can adversely affect the quality of the cut. When cutting steel mesh, it is advisable to use a moderate cutting speed to fully utilize the cutting capability of the tool while avoiding a decrease in cutting quality due to excessive speed.
2.Adjusting Cutting Angle
Cutting angle is another key factor affecting cutting quality. The correctness of the cutting angle directly impacts the stability of cutting quality. When cutting steel mesh, the appropriate cutting angle should be chosen based on the characteristics of the tool to ensure stability in cutting quality and improved accuracy.
3.Using Appropriate Tools
Different materials and thicknesses of steel mesh require the use of different cutting tools. For instance, an oxygen nozzle is suitable for cutting thicker steel mesh, while a plasma cutting machine is suitable for thinner steel mesh. Therefore, when cutting steel mesh, it is necessary to choose the appropriate tool based on the characteristics of the material to be cut.
4.Maintaining Sharp Cutting Tools
Maintaining the sharpness and condition of cutting tools is a critical assurance for cutting quality and efficiency. Before cutting, it is essential to check the sharpness and condition of the tools to avoid a decline in cutting quality due to tool failure. Regular maintenance and upkeep ensure that cutting tools remain in optimal working condition.
Steps to Cut Expanded Metal
Before you commence cutting, ensure that all your tools are prepared and safety gear is worn to maintain focus and prevent distractions. Verify the proper functioning of your tools, such as tightening a grinding disk or checking a laser cutter’s performance. Then, follow these steps:
1.Determine Necessary Shearing
Understand the required shearing for expanded metal, a term widely recognized in the industry for specifying the type of ends to be cut.
2.Take Accurate Measurements
Precision is crucial, as even a slight deviation from the correct measurement can lead to wasted metal pieces and unnecessary expenses. Make permanent marks on the metal to identify precisely where the cuts are needed.
3.Securely Clamp the Metal
To prevent sideways movement and material waste caused by the force exerted during drilling or sawing, securely clamp the expanded metal in place.
4.Elevate the Cutting Area
Place the section to be cut on a raised surface for convenience, ensuring it is not too hard to damage your tool. This prevents accidentally cutting the working surface.
5.Start Cutting from the Edge
When cutting a small piece from a larger sheet of expanded metal, commence cutting from one edge to minimize waste. Starting away from the edges increases the likelihood of generating excess scrap material.
6.Hold Tools Correctly
Hold your cutting tool firmly without applying excessive force to avoid deviations from the marked line. Maintain a steady hand, considering that the tool may move faster on expanded metal due to gaps.
8.Finish Edges with U-Edging
For a polished finish, attach U-edging to the ends of the cut expanded metal and other coarse metal types.
