2. SAFETY
Prevent Wet Storage Stain
Properly Store Grain Bin/Silo Materials Prior to Construction to Prevent Wet Storage
Strain:
Wet storage stain (rust) will develop when closely packed bundles of galvanized material such
as sidewall and roof sheets have moisture present from any source. Roof and sidewall bundles
should be inspected on arrival for the presence of moisture. If moisture is present, moisture must
not be permitted to remain between the sheets. In the case of moisture presence, sheets or
panels should be separated immediately, wiped down, dried and sprayed with a light oil or diesel
fuel.
Where possible, sidewall bundles, roof sheets and other closely packed materials should be
stored in a dry, climate controlled building. Storage inside a dry building should be done if at all
possible. Where outdoor storage is unavoidable, the materials should be raised out of contact
from the ground or vegetation. Stacking and spacing materials should not be corrosive or wet.
Materials must be protected from the weather. Weather protection that permits more air
movement around the bundles is best.
The storage method of the roof bundles and sidewall sheets may also help minimize moisture
presence. Roof bundles should be stored inclined. The bundles should be stored and secured
in a safe & stable manner. Turning the bundles over and storing with the center of the dome “up”
like a arch is an option. Sidewall bundles may be stored on edge, however these bundles
should be secured in such as way as they cannot fall over and cause injury.
Should “white rust” or “wet storage stain” occur, contact the manufacturer immediately
concerning methods to minimize the adverse effect upon the galvanized coating.
