Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall 
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If 
moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels 
immediately and wipe them down. Spray with a light oil or diesel fuel. 
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored 
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so 
that they are raised above the ground and vegetation. Any stacking and spacing materials should not be 
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the 
bundles if possible. 
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of 
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing 
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they 
do not fall over and cause injury. 
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize 
the adverse effect upon the galvanized coating.
