9.3.3.2.(1)

Intent 1:

To limit the probability that sheet steel will corrode, which could lead to premature failure.

This is to limit the probability of:

• compromised structural integrity, or
• where sheet steel is used in an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, which could lead to further compromised structural integrity.

Where sheet steel is used in assemblies that support floors, this is to limit the probability of excessive movement, vibration or deflection of floors, which could lead to negative effects on the psychological well-being of persons.
