FR4 Fiberglass Sheets – 1mm to 4mm | Cut-to-Size Quotes
FR4 Sheet Material for Machining and Insulating Components
Choose FR4 fiberglass sheet material for machined supports, insulating plates and electronic equipment projects. The epoxy-and-glass laminate combines rigidity with electrical insulating properties, making it a useful starting material for prototypes and fabricated components.
Buy a sheet or quote a finished part
Sheet material: select a listed size and thickness above, check the selected dimensions, then add the required quantity to your cart. The metric option is the ordering reference; inch sizes below are approximate.
Machined parts or non-standard sizes: send your part requirement for a quote. Include dimensions, holes or cutouts, quantity, critical tolerances, delivery postcode and any specified grade or documentation. If your design is still being tested, ask about a sample batch before production.
For drawings, email beeplastic@beeplastic.com with the product name and project details, or start with a dimensioned sketch.
This listing has 1mm, 1.5mm, 2mm, 3mm and 4mm thickness options in nine sheet sizes, including 100mm × 100mm and 500mm × 300mm. Choose the size and thickness that suit your stock-material requirement; for holes, cutouts or a finished outline, use the custom quote route below.

Frequently Asked Questions (FAQ)
Q1: Can you machine an outline or hole pattern?
Send your drawing, sheet thickness, quantity and critical dimensions. We can review CNC cutting and drilling for your part and identify any geometry that needs a sample or design adjustment.
Q2: What if my size or thickness is not listed?
Request a custom quote with your required dimensions and quantity. Material availability, processing approach and delivery timing will be checked for that requirement.
Q3: My specification requires UL94 V-0 or a material certificate. What should I send?
Include the exact grade, flame-rating and documentation requirement with your enquiry, so the required material and supporting documents can be checked before you order.
Q4: Can I use this for PCB or equipment insulation?
FR4 sheet material is used in insulating and structural components. If the part has defined voltage, temperature or safety requirements, include those limits and the specified grade in your enquiry for material review.
