Tips for Prepainted Metal Maintenance

For most buildings, the exterior is designed to be its most important eye-catching feature. While we’re wired to be extra mindful of the cleanliness and maintenance of the interior of our homes and offices, we sometimes neglect to remember to give the outside of our buildings the proper care. One of the biggest advantages of prepainted metal is its easy maintenance, but there are a few easy steps to make your metal panels shine bright.

Rinse the surface with water.

This sounds like a no-brainer, but this is one of the easiest ways to clean coated metal panels. Dirt and debris built up over time can affect the quality of the panel’s appearance and potentially reduce the lifetime of the coating. Simply rinsing the surface with a garden hose or pressure spray system will clean most buildups on a coating surface, allowing the panels to look brand new.

Clean with soap or water for difficult areas.

Preventing Job Site Storage Corrosion of Pre-painted Building Panels

Prepainted building panels have been successfully used for many years. Properly installed building panels under normal service conditions have excellent corrosion resistance and extremely long life expectancy. However, prepainted building panels may be  subject to premature corrosion failures prior to installation if they are not handled and stored properly on the job site. Excessive storage periods or poor storage conditions can result in water intrusion into panel bundles. Prolonged exposure of bundled panels to wet conditions can cause paint blistering and substrate corrosion.

Environmental and Service Conditions

Water is a necessary prerequisite for corrosion of stored prepainted panels. When water or water vapor is available along the sides of a panel bundle, it may penetrate between the panels by capillary action. If proper precautions are not taken during transport, water may be present between the panels upon delivery at the job site.

Besides water, two other important factors that contribute to the corrosion of stored pre-painted panels are temperature and exposure time. Corrosion will accelerate with increased temperature. Given enough time, panel bundles will eventually become wet and storage corrosion may occur . Customer satisfaction can be increased, and storage corrosion can be prevented by: Continue reading
