C4x5.4 — Dimensions and Section Properties

Dimensions and key properties

C4x5.4 drawn to the proportions tabulated below, with the y axis at the centroid, x̄ = 0.46″ from the back. The inner flange faces are drawn at the standard 1:6 slope, which is not exact for every size. The flange toe radius is not drawn.

Weight: = 5.4 lb/ft
A: = 1.58 in²
d: = 4 in
bf: = 1.58 in
Ix: = 3.85 in⁴
Sx: = 1.92 in³
Zx: = 2.29 in³
rx: = 1.56 in
ry: = 0.444 in
