Ultra-Strength Lightweight
Carbon Fiber Square Tubes

The strongest composite we offer, carbon fiber is comparable in strength to 6061 aluminum yet lighter in weight.

Ultra-High-Temperature
Carbon Fiber U-Channels

Unlike metal channels, these carbon fiber U-channels won’t warp at extreme temperatures, so they’re ideal for heat treating and furnace fixtures.

Ultra-Strength Lightweight
Carbon Fiber Half Rounds

The strongest composite we offer, carbon fiber is comparable in strength to 6061 aluminum yet lighter in weight.

Ultra-High-Temperature
Carbon Fiber Sheets

Unlike metal sheets, these carbon fiber sheets won’t warp at extreme temperatures, so they’re ideal for heat treating and furnace fixtures.

Ultra-High-Temperature
Carbon Fiber 90° Angles

Unlike metal angles, these carbon fiber 90° angles won’t warp at extreme temperatures, so they’re ideal for heat treating and furnace fixtures.

Easy-to-Machine Hard Fiber Sheets

Easy-to-Machine Hard Fiber Sheets

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.

Easy-to-Machine Hard Fiber Tubes

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.

Easy-to-Machine Hard Fiber Rods

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.

Electrically Insulating Hard Fiber

Also known as fishpaper.

Composite Fiber Aramid
Honeycomb Panels

testString

With an aramid honeycomb core sandwiched between carbon fiber or fiberglass for rigidity, these panels are strong, but lightweight, and won’t conduct heat. Often used as wall panels in structural and insulating applications, they’re a lightweight alternative to solid composite and aluminum honeycomb panels.

Create-Your-Own Composites

Mold custom-shaped composite parts by layering your choice of fabric with an epoxy.

Medium Density Fiberboard Sheets

Medium Density Fiberboard Sheets

Medium Density Fiberboard Sheets

Also known as MDF, these fiberboard sheets are smoother, denser, and more uniform than real wood.

Carbon Fiber Threaded Rods

Ultra-High-Temperature
Carbon Fiber Threaded Rods

Unlike metal rods, these threaded rods will not warp at extreme temperatures, making them ideal for heat treating and furnace fixtures.

Metric Ultra-High-Temperature
Carbon Fiber Threaded Rods

Unlike metal rods, these metric threaded rods will not warp at extreme temperatures, making them ideal for heat treating and furnace fixtures.
