Arc-Resistant GPO3 Fiberglass Hat Channels
- Color: Red
- Temperature Range: -50° F to 265° F
- Tensile Strength: 10,000-15,000 psi (Good)
- Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
- Hardness Rating: Barcol 50 (Hard)
- For Use Outdoors: No
- Specifications Met: UL 94 V-0
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. All of these hat channels are arc and track resistant. They also have better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're often called polyester-grade industrial laminate.

Ultra-Strength Lightweight Carbon Fiber U-Channels
- Color: Black
- Tensile Strength: 103,000 psi (Excellent)
- Fiber Tensile Stiffness: Standard (33-36 msi)
- Maximum Temperature: 275° F
- Impact Strength: Not Rated
- Hardness: Not Rated
- For Use Outdoors: No
Often used to make railings, edge covers, and other structural framing parts, these carbon fiber U-channels add stiffness and strength to applications without adding a lot of weight. They’re similar in strength to 6061 aluminum yet lighter in weight. With a plain weave and 0°/90° construction layup, all are easy to machine. They won’t splinter when cut.

Ultra-High-Temperature Carbon Fiber U-Channels
- Color: Black
- Tensile Strength: 11,000 psi (Good)
- Maximum Temperature: 5,000° F
- Impact Strength: Not Rated
- Hardness: Not Rated
- For Use Outdoors: No
Unlike metal channels, these carbon fiber U-channels won’t warp at extreme temperatures, so they’re ideal for heat treating and furnace fixtures. They are lightweight with an excellent strength-to-weight ratio and the material heats up quickly to reduce cycle times.
