Important Do not assemble or install damaged components. 4.3. Product Storage Brownie Bin Stairs parts should be stored in a clean, dry location to prevent rust and corrosion of steel components. For outdoor storage, protection should be provided. Rust on Galvanized Parts 1.
Page 10: Component Locations
Due to safety concerns with installation and use, Brownie does not recommend the use of oil on other parts such as roof sheets, rungs, treads, and platforms. 4. If moisture is left on parts, this white rust can become more aggressive and turn into red rust. Red rust can cause degradation in the material and become a structural concern.
