Fiberglass

Structural FRP Fiberglass 90° Angles

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

Structural FRP Fiberglass Square Tubes

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

Structural FRP Fiberglass I-Beams

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

Structural FRP Fiberglass U-Channels

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

Arc-Resistant GPO3 Fiberglass U-Channels

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

Arc-Resistant GPO3 Fiberglass 90° Angles

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

Arc-Resistant GPO3 Fiberglass Hat Channels

Unlike similar U-channels, these GPO3 fiberglass hat channels have flanges for mounting to flat surfaces. Use them to route and insulate wire in humid environments.

Arc-Resistant GPO3 Fiberglass Square Tubes

Route and insulate wire using these square fiberglass tubes, which fit better along edges and around corners than round tubes.

Flame-Retardant FRP Fiberglass 90° Angles

Made with a flame-retardant resin, this FRP fiberglass meets ASTM E84 Class A.

Multipurpose Flame-Retardant Garolite G-10/FR4

Multipurpose Flame-Retardant
Garolite G-10/FR4 Angles

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94V0 for flame retardance.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Rectangular Tubes

These rectangular tubes are flame retardant, machinable, and electrically insulating.
