What is the web thickness in inches of a C8x18.5?

In structural steel design, a C8x18.5 refers to a specific model of a C-channel section. The designation includes the depth of the channel (8 inches) and its weight per unit length (18.5 pounds per foot). The web thickness is a critical dimension that contributes to the strength and load-bearing capacity of the channel.

For a C8x18.5, the standard specifications indicate that the web thickness is indeed 1/2 inch. This thickness ensures that the channel can adequately handle shear stresses and other forces experienced in structural applications.

Understanding the thickness of the web is essential for engineers and designers, as it affects the overall structural performance, including buckling resistance and flexibility. Knowing standard specifications for various steel shapes, including C-channels, helps professionals make informed decisions during design and construction processes.
