Prestressed steel should be stored in dry storage.For open-air and on-site storage, sleepers should be erected on the ground, strictly in direct contact with the wet ground, and covered with tarpaulins or rainproof sheds to shorten the storage period as much as possible. For special environments, anti-rust packaging should be used when ordering.Floating rust on the surface of prestressed steel will not affect its use, but rusting into visible "pits" will affect its mechanical properties.
