AISI North American Specification
North American Specification for the Design of Cold-Formed Steel Structural Members
What it measures
The design code for cold-formed steel: how to calculate the capacity of a stud, a track or a header made from thin sheet, including the local buckling behaviour that thin steel is prone to.
Why it matters for a panel envelope
A Shield™ panel is cold-formed steel, so this is the code an engineer designs it to and a plan reviewer checks it against.
