Visual Acceptance for Single-Skin Architectural Metal Wall Panels

While the building and fire codes are primarily concerned with structural and fire performance of single-skin architectural metal wall panels, there are often other performance indicators used within the construction industry to define an acceptable application. Single-skin architectural metal wall panels are most often defined as those metal sheets and coils that are natural metals (copper, zinc, etc.), stainless steel, or coated-metals that have a surface layer added (painted, dipped, plated, etc.) to a metal substrate. Visual appearance is often defined in architectural specifications that are based on code requirements, architectural requirements, and appearance goals that are beyond the scope of the code. This document states the unified position of the Metal Construction Association and its members with regards to visual acceptance parameters.
