C10x15.3 Channel FAQ
What does C10x15.3 mean?
C means American Standard channel. The first number (10) is the nominal depth in inches, and the second number (15.3) is the weight in pounds per foot. The actual depth of C10x15.3 is 10 in.
How much does a C10x15.3 channel weigh?
C10x15.3 weighs 15.3 lb per foot (22.8 kg per meter). A 20 ft length weighs about 306 lb.
What is the metric equivalent of C10x15.3?
The metric (SI) designation is C250x22.8: 254 mm deep with a 66 mm flange and 22.8 kg/m.
Where is the centroid of a C10x15.3 channel?
A channel is not symmetric about its vertical axis. The centroid of C10x15.3 sits 0.634 in (16.1 mm) from the back of the web, and the shear center is 0.796 in from the web centerline, on the side away from the flanges.
What size load can a C10x15.3 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.
