is the section modulus of wood plastic fence

Section Modulus - an overview | ScienceDirect Topics

The plastic section modulus, Zx, is used to determine the limit-state of steel beams, defined as the point when the entire cross section has yielded. This property is unique to steel, since neither of the other materials we are considering (wood and reinforced concrete) has the necessary ductility to reach this state.

One of the most significant differences is the lower stiffness (modulus of elasticity) of plastic lumber. Pine and oak typically have a modulus of at least 6.9 GPa, which is higher than that of plastic lumber without a filler. Mechanical properties of s depend on the time and temperature at which stress is applied.
