About Composites

Structural FRP Fiberglass Rods

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Arc-Resistant GPO3 Fiberglass Rods

Offering excellent arc and track resistance, this GPO3 fiberglass is often used for electrical applications in humid environments.

Garolite

Multipurpose Flame-Retardant
Garolite G-10/FR4 Rods

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Discs

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

High-Temperature Garolite G-11 Rods

Offering higher strength and better heat resistance than Garolite G-10/FR4, Garolite G-11 is suitable for continuous use in elevated temperatures.

Economical Electrical-Insulating Garolite XX Rods

Stronger than Garolite CE with better electrical-insulating properties, Garolite XX is often fabricated into low-cost electrical components.

Halogen-Free Garolite G-10 Rods

Use Garolite G-10 in place of Garolite G-10/FR4 for applications that are sensitive to halogen, such as in nuclear plants. It's strong, machinable, and electrically insulating.

Economical Garolite CE Rods

Garolite CE is often fabricated into parts where high strength is not required.

Ultra-High-Temperature
Arc-Resistant Garolite G-7 Rods

Choose these Garolite G-7 rods for their high heat tolerance—they withstand temperatures up to 425° F. While not as strong as Garolite G-9, they offer better arc resistance in dry environments.

Easy-to-Machine Garolite LE Rods

Using nothing more than standard high-speed steel tooling, Garolite LE can be machined into intricate parts.

Arc-Resistant Garolite G-9 Rods

Frequently called electrical-grade Garolite, this Garolite G-9 is strong, electrically insulating, and arc resistant in dry environments.
