All Allsteel panels and trim are designed to withstand severe rain and wet weather conditions. Neither painted nor Galvalume finishes are designed to be in continuous contact with water for long periods of time. Damage will result if uninstalled panels or trim are allowed to remain wet in storage. Be sure to store material that will not be installed immediately in a dry location. Wet material should be air-dried and re-stacked if installation is not planned right away.
