FRP is a common abbreviation for Fiberglass Reinforced Plastic. It is a strong, durable, and relatively lightweight material suitable for various wall paneling purposes. Cutting FRP panels accurately and cleanly is essential to achieving a professional finish.
Before you install this type of panel, it must be cut to fit your walls’ size. The following outlines the steps to cut FRP panels.
How to Cut FRP Panels in Four Steps
To cut the FRP panel, consider a few things: how much you need to trim away and the inevitable material contraction and expansion size. In this article, we’ll explore the tools and techniques for cutting FRP panels, including using carbide-tipped tools and metal shears and achieving fine-tooth straight cuts.
For the thicker panel, it’s more convenient to use a mechanical saw or drill with carbide coats. The tool must be sharp and clean as the glass fiber is severely abrasive.
After you’ve gathered all your supplies, tools, and safety equipment, it is time to execute the cutting process. Here is the guide to what you have to do:
1. Put on the safety equipment as your protection
Safety glasses and leather gloves are essential. A respirator is also necessary to prevent dust from the paneling pieces that fly around in the air.
2. Measure the size
The next step in cutting FRP panels is to use a tape measure and apply it to the glass fiber sheet. Mark the edge of your cutting panel using a carpenter pencil. Repeat this step to create a symmetrical line across the board. You might want to complete this step by putting the FRP sheet over the table to provide a sturdy and solid surface.
3. Utilize a circular saw to cut your panel
Carbide-tipped tools are excellent for cutting FRP panels due to their durability and precision. The carbide tips are incredibly hard, making them ideal for using abrasive materials like FRP.
Create a line between two marks, a pencil, and a chalk line that sets the carbide blade from a circular saw. The circular saw must be placed on the right of the line to make it noticeable from the table’s edge. Ensure the sheet is facing down, but if you’re cutting FRP with a table saw, ensure it is facing up.

After setting the marking line, align the circular saw’s carbide blade with the guiding chalk line. Then, press the tool’s trigger and move it slowly against the fiberglass sheet. The circular saw’s carbide blade must be kept aligned throughout the cutting process.
4. Complete the process of cutting the panel
Learning how to cut FRP panels with a utility knife might be challenging, but the knife can be used as part of the finishing process. Place the sharp side of your knife against the FRP sheet.
Tilt the sharp side at a 15° angle, then drag it on the panel edge to get rid of the burr edge. Remember not to push the blade as it will damage your sheets overly.
Experience
Having worked with FRP panels for several years, I can attest to the importance of using the right tools and safety equipment. On one occasion, using a dull blade resulted in frayed edges and increased dust, emphasizing the need for sharp, carbide-tipped blades.
Additionally, when cutting thicker panels, I found that using a mechanical saw with carbide coats significantly improved the cut’s precision and ease.
Metal Shears for Quick Cuts
Electric or pneumatic metal shears are excellent for quickly cutting straight lines in FRP panels. They function by “biting” through the material, making them perfect for long, straight cuts.
Steps:
- Mark your cut line using a straightedge or square.
- Line up the metal shear with the marked line.
- Cut along the line with a consistent feeding rate to prevent chipping or cracking.
Additional Insights from Experts
Experts suggest using a jigsaw with a fine-tooth blade for the best results, especially when dealing with intricate cuts or thicker materials. This tool offers greater control and precision, particularly for curved cuts or smaller sections.
Comparison of Tools for Cutting FRP Panels
| Tool | Best For | Pros | Cons |
|---|---|---|---|
| Circular Saw | Straight cuts | Slower than a circular saw | Requires careful handling |
| Utility Knife | Finishing edges | Precise edge trimming | Not suitable for primary cuts |
| Metal Shears | Long, straight cuts | Quick, efficient for straight lines | Limited to straight cuts |
| Jigsaw | Curved or intricate cuts | Fast, efficient, and precise with carbide tips | Slower than circular saw |
In my experience, using a jigsaw for detailed work on FRP panels ensures cleaner cuts without the risk of cracking or chipping, particularly for custom shapes or smaller panels.
Conclusion
Cutting FRP panels requires the right tools, accurate measurements, and safety precautions. By following these guidelines and leveraging personal experience and expert recommendations, you can achieve a professional finish with your FRP paneling projects.
Whether using a circular saw for straight cuts or a jigsaw for detailed work, each tool offers unique advantages to suit different cutting needs.
