Fiberglass

Structural FRP Fiberglass
Sheets, Bars, and Strips

Structural FRP Fiberglass Sheets, Bars, and Strips

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

Arc-Resistant GPO3
Fiberglass Sheets and Strips

Arc-Resistant GPO3 Fiberglass Sheets and Strips

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

Flame-Retardant FRP
Fiberglass Sheets and Bars

Flame-Retardant FRP Fiberglass Sheets and Bars

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

High-Temperature FRP Fiberglass

With more than twice the heat tolerance of standard FRP fiberglass, this material withstands temperatures up to 370° F.

Chemical-Resistant FRP Fiberglass

This FRP fiberglass is made with a chemical-resistant resin that stands up to harsh environments.

Garolite

Multipurpose Flame-Retardant
Garolite G-10/FR4 Sheets and Bars

Multipurpose Flame-Retardant Garolite G-10/FR4 Sheets and Bars

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

Halogen-Free Garolite
G-10 Sheets and Bars

Halogen-Free Garolite G-10 Sheets and Bars

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.

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

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

Garolite G-7 withstands temperatures up to 425° F—higher than any other grade of Garolite. While not as strong as Garolite G-9, it offers better arc resistance in dry environments.

Impact-Resistant Garolite E-Glass

Impact-Resistant Garolite E-Glass

A combination of high impact strength and extreme hardness makes Garolite E-glass very difficult to penetrate. It is often used for machine guards.

High-Temperature
Garolite G-11 Sheets

High-Temperature Garolite G-11 Sheets

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

Arc-Resistant Garolite G-9 Sheets

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

Grating and Flooring

Traction Floor Plates

Add permanent slip resistance to floors, ramps, stairs, and docks with these solid plates.

Fiberglass Stair Treads

Fiberglass Stair Treads

These lightweight fiberglass treads are corrosion resistant, nonconductive, and nonmagnetic.

Stair Tread Nosing

testString

Screw nosing into place to protect the front portion of the stair and provide a slip-resistant surface.

Stair Tread Covers

testString

Protect stairs from wear or provide a new stair surface on worn stairs.
