Frequently Asked Questions

  • Are channels an extruded product?


    Yes, aluminum channels are made through the process of extrusion. The 6000 aluminum series, and 6063 aluminum in particular, is considered among the best alloys for extruded aluminum. First, the aluminum is heated, then pushed through a die. For channels, this die will be shaped like the letter C, but with a straight back to form 90 degree angles. Once aluminum angle cools and hardens it will be cut to length.

  • What is the difference between aluminum channels and aluminum angles?


    These extruded shapes are similar in that neither are designed for extreme weight bearing applications. They are more commonly used in structural support, as bracing or frame work. The main difference between an angle and a channel is the shape. Angles look like an uppercase L, and channels look like a straight backed C.
