White Paper
Preformed Metal Wall Fabrication/ Installation Tolerances
The truth is that there are any number of combinations for installation and fabrication tolerances for preformed metal used in roofing and wall construction. The basic rule of thumb is: “Everything should look straight when viewed from a distance of 25'. Particular products or applications might require more stringent tolerances to assure performance.”
This document will discuss procedures that have been used by a number of MCA members for many years. This information is primarily derived from the Preformed Metal Wall Specification Guidelines that was developed in the 1990’s to address a series of topics important to the preformed metal wall industry.
