ASTM C 645 covers the material and manufacturing tolerances and corrosion protection requirements are governed by ASTM A1003/1003M. The standard for non-structural studs is base metal thickness of 18 mil and a minimum galvanized coating of G40 for corrosion protection. Because residential walls are typically closer together, they are frequently bumped and could be dented during construction.

While structurally not necessary, they are selected and used for their durability. On the other hand, residential framers often use minimum 33-mil studs for non-structural walls to prevent the stud from bending or being damaged. These walls typically have longer spans, are taller and use intermediate bridging. However, framers often use thinner, less expensive studs for these walls.Д¬ommercial framers typically use 18, 27 and 30 mil studs, also known as drywall studs, to frame non-structural or partition walls. The studs for non-structural walls may be the same size and thickness as those used in exterior walls.

Because non-structural walls are not vital to the structural capabilities, inline framing does not have to be followed. Non-structural walls do not support or carry the weight of the structure. Many builders, framers and vocational technical schools have started their expansion to steel framing with this method. Looking for a slow transition to cold-formed steel? Non-structural walls may be your answer.
