C6x8.2 Channel FAQ
What does C6x8.2 mean?
C means American Standard channel. The first number (6) is the nominal depth in inches, and the second number (8.2) is the weight in pounds per foot. The actual depth of C6x8.2 is 6 in.
How much does a C6x8.2 channel weigh?
C6x8.2 weighs 8.2 lb per foot (12.2 kg per meter). A 20 ft length weighs about 164 lb.
What is the metric equivalent of C6x8.2?
The metric (SI) designation is C150x12.2: 152 mm deep with a 48.8 mm flange and 12.2 kg/m.
Where is the centroid of a C6x8.2 channel?
A channel is not symmetric about its vertical axis. The centroid of C6x8.2 sits 0.512 in (13 mm) from the back of the web, and the shear center is 0.599 in from the web centerline, on the side away from the flanges.
What size load can a C6x8.2 channel carry?
Capacity depends on the span, load, bracing, connections and local building code, so it cannot be read from a size table. A licensed structural engineer must size any channel that carries a load.
