Where problems start
The Aluminum Association says virtually all aluminum staining problems happen during shipping, handling or storage.
A U.S. Steel job-site bulletin shows scratches from handling on painted panels leading to corrosion, and says damaged panels should not be installed.
Handling and storage can also hurt people: lifting, sharp edges and stacks that shift. This module covers all three.
