Fabricating Fibergrate Structural Shapes

For small projects, abrasive masonry blades and gritted carbide blades will work. For larger projects, diamond-gritted tooling is recommended. These tools are much more aggressive than masonry and other diamond tools, which are available at your local hardware store. Carbide, high-speed steel, and diamond tools such as those obtained at the hardware stores will have a concise service life when used on FRP materials.

Use a rotary saw for straight cuts and a jig saw for circular cuts. Use even steady pressure when cutting. Excessive pressure may cause heat or ragged edges. Replace dull blades to prevent buildup.

Drilling

For a small number of drilled holes, you can use a carbide-tipped masonry bit. For larger projects, use a diamond-gritted drill bit.

Sealing

All cut edges must be sanded smooth and sealed. 80-grit paper is recommended, and a high-speed sanding wheel is used for the best results. After sanding, use a sealing kit designed to be used on fiberglass.

Recommended Safety Practices

Before cutting Fibergrate products, take the following steps:

  1. Carefully read the Material Safety Data Sheet (MSDS). If you do not have an MSDS, one is available upon request. Individuals with respiratory ailments should not fabricate FRP products.
  2. Observe common safety precautions when using cutting tools. Always wear gloves when handling Fibergrate products. Wear approved safety glasses or goggles to protect the eyes and a respirator (mask) to reduce inhalation of dust. We recommend the use of a NIOSH/MSHA-approved mask for dust with a permissible exposure limit (PEL) of not less than 0.1 mg/M3.
  3. Dust from cutting FRP products can cause skin irritation. Wear clothing to reduce dust from coming in contact with the skin. If cutting produces difficulty in breathing or excessive skin irritation, stop immediately and consult a physician.
  4. Observe common safety precautions when using the sealing kit. Please read and follow the instructions for the kit before using it. Always wear safety glasses and protective clothing when working with FRP products or using a seal kit. Do not allow resin or catalyst to come in contact with skin.
