Notes

  • Aluminum Association standard channels are named depth x weight: 4 x 1.74 is a 4 in deep channel weighing 1.74 lb per foot. Flanges are parallel and constant thickness.
  • Dimensions, including the printed fillet radius R at the web-to-flange corners, are from the Aluminum Association Standard Structural Profiles table as reproduced by Engineers Edge. Flange tips are drawn square (no tip radius is printed). The drawn area is within 5 % of the printed area on every size.
  • Files are 4 in (101.6 mm) long along X, web back at y = 0 and flanges toward +y. The source table shows the 12 in deep, 5 in wide size as '2 x 11.8': it is 12 x 11.8.
