The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

An anodized coating on these U-channels forms a bond with the aluminum surface to improve wear and corrosion resistance.

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications.

Often called architectural bronze, 385 brass is easy to machine and has excellent formability when heated. It is typically used for handrails, ornamental trim, and hardware, such as hinges and lock bodies.

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Known for its naturally slippery surface, PTFE surpasses most plastics when it comes to chemical resistance and performance in extreme temperatures.

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.

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