How to Cut Fibreglass Grating: Your Quick Guide

Whether you’re researching how to cut fibreglass grating (GRP grating) as part of exploring this versatile material or you already know it is a great choice for your project, this quick guide explains how easy working with GRP grating can be.  

Compared to steel:

• GRP grating is significantly lighter and easier to transport, handle, and install. 
• It reduces strain on support structures and simplifies maintenance tasks. 
• It is resistant to corrosion, rust, and rot (ideal for corrosive environment applications).
• GRP panels take roughly one-third of the time to install and about 40% fewer people. 

...and, while it’s important to learn how to cut fibreglass grating if you haven’t worked with it before, the process is fairly straightforward.

Before starting, observe some common sense safety precautions:

1. 1. Wear appropriate personal protective equipment (PPE) to protect yourself from potential hazards. Wear safety glasses and a dust mask (NIOSH/MSHA approved, with a permissible exposure limit (PEL) of not less than 0.1 mg/m³). This is essential to shield the eyes and respiratory system from fibreglass dust particles. Note that if you have a respiratory ailment, you should not fabricate GRP products.
    
   2. Always wear gloves when handling and cutting GRP grating.
      
      
   3. Wear clothing to reduce exposure to dust, which can cause skin irritation.
      
      
   4. Review and follow epoxy coating or sealing kit safety procedures prior to use.
      
      
   5. Ensure that the work area is adequately ventilated to prevent the accumulation of airborne fibers.
      
      
   6. Familiarize yourself with the safety data sheets (SDS), for your chosen product. These will outline the necessary precautions and handling procedures. 
      

The required tools include:

1. Safety glasses, dust mask, and other essential PPE
2. A measuring tape for accurate measurements
3. Cutting equipment appropriate for your installation, which may include a circular saw, jigsaw, or grinder
4. Clamps to secure the grating and a marking pen to create precise cutting lines

Before you begin:

1. Ensure your work area is clear of any obstacles that could hinder your movements, including any debris or tools that could interfere with the cutting process. 
2. Set up a stable work surface or workbench where you can securely place the grating for cutting. 
3. Arrange your tools and materials within easy reach, promoting efficiency and minimizing the risk of accidents.

As with any construction material, “measure twice, cut once” applies when cutting fibreglass grating to ensure a proper fit:

1. Identify the correct dimensions for the grating based on your installation requirements.
2. Using a measuring tape to measure the length and width accurately, mark the cutting lines with your marking pen. 
3. Double-check the measurements before proceeding to the cutting stage to avoid costly mistakes.

Note: Support the panel to make sure it doesn’t move or flex while you’re cutting. 

The choice of cutting method depends on the thickness of the grating and the complexity of the cut:

• For straight cuts, a circular saw with a fine-toothed blade is often the most efficient option. 
• If you need to make curved or angled cuts, a jigsaw with a fibreglass-cutting blade can provide the necessary precision. 
• In some cases, a grinder with a cutting wheel can be used for intricate cuts.

In all cases, remember to follow the manufacturer's instructions for each cutting tool and wear appropriate PPE throughout the process.

After cutting the fibreglass grating:

1. Inspect the cut edges for any roughness or imperfections. 
2. Smooth out any unevenness using a file or sandpaper. 
3. Double-check all edges, ensuring they are smooth and free from sharp protrusions that could pose a safety hazard during installation or handling.
4. Use an epoxy sealer to coat sanded/cut surfaces to prevent corrosive chemicals from reaching exposed glass fibres.

Safely dispose of any fibreglass dust or debris generated during the cutting process. Fibreglass dust can irritate the skin, eyes, and respiratory system, so it is crucial to handle it with care. Clean the work area thoroughly, removing any remaining dust or debris. Store your tools and leftover materials properly to maintain their longevity and ensure they are ready for future use.
