Aluminum 6061 U-channels are easy to machine and form. They are weldable with traditional and furnace brazing techniques and maintain their shape and strength over time. Type 6061 aluminum is the most commonly used and functional heat-treatable aluminum alloy.

These architectural 6063 aluminum U-channels have sharp, right-angled inside and outside corners. U-channels are commonly used for shower enclosures, sliding glass doors, and cabinets in homes or commercial spaces. They have high tensile strength and resist corrosion.
