Frequently Asked Questions

  • What are the difference between the types of channels?

    Aluminum channels are an extrusion product and are most commonly seen in the shape of a straight-backed uppercase C, wherein the legs are of equal lengths and equal thicknesses, and can be either parallel or rounded. However, channels are also available in what are called hat/furring channels, and strut channels. They differ not only in shape but application. Strut channels, for example, have holes along the length of the web, making it great as support for mechanical components and wiring. Hat channels have added flats on each leg that run parallel to the web making it possible to attach to flat surfaces on either side with ease, so they are often seen in masonry.
