In addition to the information listed above, the inside flange surfaces of “C” shapes have a slight angle or slope. The nominal slope of the inside flange surfaces is 16.7% or 9.46 degrees.

C8x11.5 Weight

American standard channel forms are designated by their depth x weight. The C8x11.5 designation means that the channel weighs 11.5 pounds per foot. Therefore, a 10-foot length of C8X11.5 channel weights 115 pounds and a 20-foot section of C8X11.5 weighs 230 pounds.

C8x11.5 to Metric

The closest metric equivalent to C8x11.5 is C200x17.1, which has the following specifications:

Depth 8.00 in.
Mass 17.1 kg/m
Area 2180 mm2
Flange Width 57 mm
Flange Thickness 9.9 mm
Web Thickness 5.6 mm

C8x11.5 Section Properties

C8x11.5 Area Moment of Inertia

The area moment of inertia (or second moment of area) for a C8x11.5 channel about the X-axis can be calculated from the following formula:

The area moment of inertia of C8x11.5 about the X-axis is approximately 32.4 in4 (13.5×106 mm4).

C8x11.5 Section Modulus

The elastic section modulus for a C8x11.5 channel about the X-axis is calculated from the equation below:
